Why is my SimpliSafe base station red? On a Gen 3 system (bought 2018 or later) a red light means one of two things. A continuous red pulse that turns solid after 1 to 2 minutes means there was a recent alarm, and it stays solid until you clear it on the keypad. A slow red pulse, once every 8 to 10 seconds, is a minor system error such as radio interference, with the details on the keypad. On the Original SimpliSafe (2017 or earlier) solid red means the SIM card is not seated and intermittent red blinking means no cellular connection. How to read and clear each red light.

A SimpliSafe base station that's gone offline shows up two ways: the app says the system is offline or "unreachable," or the base station itself announces "No Link to Dispatcher." They come from the same root cause - the base station has lost its connection to your network and, on monitored plans, to the cellular backup too - so the fix sequence is the same. Work these steps in order. Most people are back online at step 2 or 3, and the single most common modern cause (a new mesh router) is one many owners never think to check.

Before you start, know which state you're actually in, because it changes how urgent this is. If you're on a monitored plan (Standard, Pro, Pro Plus, Core), "No Link to Dispatcher" means the base station has lost both WiFi and cellular and the monitoring center cannot see your alarms right now - worth fixing today. If you're on self-monitoring or basic app control, an offline base station means you've lost app control, notifications, and camera recordings, but a local siren can still sound; it's an inconvenience, not a safety gap. Either way, the sensors and siren themselves keep talking to the base station over their own radio - this outage is about the base station reaching the outside world, not about your doors and windows.

Before anything else: which SimpliSafe is this? The same light means opposite things

SimpliSafe publishes a separate light chart for each generation, and on the point that matters most they disagree. A solid red light on a Gen 3 base station means a recent alarm. A solid red light on the Original system means the SIM card is not seated properly. Those are not variations on a theme. One says somebody may have been in your house; the other says a piece of plastic needs pushing back into its slot.

So the first question is not what colour the light is. It is which box you own. SimpliSafe's own test is the keypad: if you bought the system in 2018 or later you almost certainly have Gen 3; a system bought in 2017 or earlier is the Original SimpliSafe (sometimes called SS2). Get this wrong and every light in the table below misleads you.

That last row is worth pausing on, because "my SimpliSafe base station has no light" is one of the most common ways people describe this problem and on a Gen 3 it is usually not a problem at all. Off means unarmed. An unlit base station in a disarmed house is the base station doing exactly what it is supposed to do. Check the app or the keypad before you conclude the hardware is dead.

Why is my SimpliSafe base station red? Flashing, solid and slow-pulse red

SimpliSafe's own red-light article says a Gen 3 base station pulses red for two different reasons, and the timing of the pulse is how you tell them apart. Look at the light for about 20 seconds before you do anything else.

Flashing red that turns solid: there was a recent alarm

A continuous red pulse for 1 to 2 minutes, followed by a solid red light, means a recent alarm. The light is a reminder of the event rather than a live alarm: it stays solid red after the siren has stopped, and it keeps showing until someone clears the warning on the keypad or disarms and re-arms the system. Check the keypad or the app timeline to see which sensor triggered and when. A red light you did not expect is worth that check, because it is the base station telling you something happened while you were not looking.

A slow red pulse every 8 to 10 seconds: a minor system error

A slow pulse with 8 to 10 seconds between each flash is not an alarm. SimpliSafe describes it as a minor system error and gives radio interference as its example. The keypad shows the details, and SimpliSafe's instruction is to fix the error itself; the light is only reporting it. If the keypad points at a single sensor, our SimpliSafe sensor not responding guide covers the per-device fixes. If it points at interference, the placement step below is the place to start. If the door chime has gone quiet rather than the whole system, see SimpliSafe door sensor not chiming.

How to clear the red light on a SimpliSafe base station

  1. Press Off on the keypad to disarm the system.
  2. Press the keypad screen toward the warning symbol (SimpliSafe's light-settings article describes this as the right arrow button).
  3. An error message appears. Select Clear.
  4. That clears the message on the keypad and resets the red LED on the base station.

If the red light persists after clearing, SimpliSafe's next step is to power cycle the base station, which is the Gen 3 reset in Step 4. Do not use the Base Station Light setting to make it go away: switching the LED off hides the reminder without clearing the event, which is covered in the light won't turn off below.

Red on an Original SimpliSafe means something else entirely

On the Original system (2017 or earlier) red is a connection and hardware signal, not an alarm reminder. Solid red means the SIM card is not seated properly. Intermittent red blinking means no cellular connection. A single red blink is normal: SimpliSafe says it means the base station sent, or is sending, a signal. The SIM fix and the cellular-module warning are in the Original hardware section.

Is a red light the same as "offline" or "No Link to Dispatcher"?

On a Gen 3, no. SimpliSafe's light chart ties red only to a recent alarm or a minor error. A lost connection is announced by the keypad and the app, and "No Link to Dispatcher" is one of the causes SimpliSafe lists for the Trouble Signal, which shows as blinking yellow with a three-tone sound. On an Original system the two can overlap: intermittent red means no cellular connection, and on a monitored plan losing cellular is half of what "No Link to Dispatcher" describes. That overlap is our reading of the two SimpliSafe articles side by side, not a statement SimpliSafe makes.

The full Gen 3 light chart

SimpliSafe states that the colours below are the only ones a Gen 3 base station displays, and that if you are seeing something not on this list you should change the lighting in the room, because ambient light distorts how the colours read.

Separately, SimpliSafe publishes a different set of light behaviours for Active Guard Outdoor Protection subscribers: a pulsing amber light means an agent is viewing your cameras to decide whether to intervene, and an amber "search light" means an agent has judged there is a potential threat and is speaking through two-way audio. If you subscribe to that service, amber is a person watching, not a fault.

"No Link to Dispatch Center" and "No Link to Dispatcher" are the same problem

A lot of people search for dispatch center. The string SimpliSafe actually publishes, on both the Gen 3 and the Original article, is "No Link to Dispatcher". The place it cannot reach, in SimpliSafe's own wording, is the Monitoring Center. If you are hunting for a "dispatch center" error and finding nothing on SimpliSafe's site, that is why: the two halves of the phrase come from two different sentences.

What the error means depends entirely on your plan, and SimpliSafe is explicit about this:

  • On a monitored plan (Pro Plus, Pro, Core, Standard, or the business equivalents), it means the base station has lost both its WiFi and its cellular connection and cannot communicate with the Monitoring Center.
  • On Self Monitoring with Camera Recordings, or Basic App Control, it means the base station has lost WiFi only, and cannot reach SimpliSafe's servers, the mobile app, or the Monitoring Center.

That distinction decides how fast you need to act. On a monitored plan, two independent connections are down at once and nobody is watching your alarms. On self monitoring there is only one connection to lose, so the same message is a smaller event.

Step 1: Confirm the base station actually has power

Obvious, but it's the top cause and the fastest to rule out. The base station runs on wall power with a battery backup, so a base station that looks "on" can still be running down a dying battery after the outlet quietly stopped working.

  • Check the outlet, not just the cable. Plug a phone charger or lamp into the same outlet to confirm it's live. Half-switched outlets (controlled by a wall light switch) are a classic culprit, and this one is not folklore: SimpliSafe explicitly advises against using an outlet connected to a light switch, because when the switch cuts power the backup batteries engage and the system reports frequent "Power Outage" errors. If your timeline is full of power-outage entries and nobody in the house has lost electricity, look at the light switch nearest the base station before anything else.
  • Reseat the power adapter at both the wall and the base station. Use the original SimpliSafe adapter if you can; underpowered third-party USB supplies can leave it in a brown-out state that connects to nothing.
  • If it was running on battery, give it a few minutes of solid wall power before judging whether it reconnects. A base station recovering from a fully drained backup battery needs time.

Step 2: The WiFi problem - and the mesh-router trap

If power is fine, the base station has lost its WiFi. Start with the boring fix, then check the trap that catches most people in 2026.

First, restart the network. Power-cycle your router (unplug 30 seconds, plug back in), wait two to three minutes for it to fully come up, then give the base station another couple of minutes to find it. A large share of "offline" reports are nothing more than a router that hiccupped.

Then check whether anything about your WiFi changed. The base station stores one network and one password. If you got a new router, changed the WiFi password, or switched internet providers, the base station is still trying to reach a network that no longer exists. You have to teach it the new one from the keypad: Menu → enter your PIN → System Settings → Wi-Fi → Edit → choose your network → "Use" → type the password in ABC mode, which works like predictive text on an old phone.

Which route you should use depends on your plan, and this is the step people waste the most time on. SimpliSafe states that the in-app WiFi steps are only for plans that include built-in network backup. If you are not professionally monitored, SimpliSafe tells you to use the keypad rather than the app. So an unmonitored owner following app instructions is following instructions written for somebody else's plan, and will keep failing at the same screen. SimpliSafe also says to fall back to the keypad if the app route fails even on a monitored plan.

One step that is easy to skip and worth doing: once WiFi is back, SimpliSafe asks you to put the system into Test Mode from the keypad to re-establish the signal, then exit it, then check the app timeline for a "User Initiated Test" entry. That entry is your confirmation the fix actually took, rather than an assumption that it did. If you are monitored, expect an automated call asking you to confirm you started the test; if you miss it, SimpliSafe leaves a voicemail and nothing further happens.

The mesh-router 5 GHz trap - check this before anything drastic. The Gen 3 SimpliSafe base station connects only to 2.4 GHz WiFi and cannot even see a 5 GHz network. Most modern mesh systems (eero, Google Nest WiFi, Orbi, Deco) ship with both bands merged under a single network name and use "band steering" to decide which band each device gets. That steering frequently pushes the base station toward 5 GHz, where it silently fails to connect - so a system that worked for years drops offline the day a new mesh router arrives. Two fixes, either works: (1) in your router app, create a separate 2.4 GHz-only network name and connect the base station to that, or (2) temporarily disable band steering while you run WiFi Setup. This one cause explains a huge share of "suddenly offline after new router" cases.

Two more network requirements worth verifying if setup keeps failing: the network must use WPA2, WPA3 or WPA2/WPA3 mixed-mode security and must have a password (open networks and networks with a sign-in portal are not supported), and neither your network name nor your password can be longer than 31 characters. Both are easy to overlook after a router upgrade defaults to WPA3.

Step 3: Fix the placement

If the base station connects but keeps dropping, or shows a weak signal, where it sits matters more than people expect. SimpliSafe's own guidance: keep it at least three feet off the ground, in open air, resting on or near non-dense material like wood or glass - not inside a cabinet, not in a closet, not on or behind metal, and not tucked against a concrete wall or a stack of electronics. Moving it from inside a media cabinet to an open shelf a few feet up is often the entire fix for an intermittent connection.

Step 4: Reset the base station, and use the right procedure for your generation

If power, WiFi, and placement all check out and it's still offline, reset the base station to force a clean reconnect. The two generations do not share a procedure. The waits differ by a factor of four to six, and the order of the power cable and the battery is reversed between them. Both procedures need a Phillips head screwdriver, because on both the battery compartment is held shut by a screw.

The two published reset procedures, step for step. Source: SimpliSafe Support "No Link to Dispatcher Warning" articles for Gen 3 and Original SimpliSafe, both updated June 26, 2026, read August 25, 2026.

The practical consequence is that the two most-repeated numbers on the internet for this reset, "ten seconds" and "sixty seconds", are both correct, for different machines. If you have a Gen 3 and you pull the battery for fifteen seconds, you have not performed the reset SimpliSafe documents.

If it comes back online but you still see "No Link to Dispatcher" specifically on a monitored plan, the WiFi may be fine while cellular is the weak link - move the base station toward a window or a room with better cell coverage, since the backup radio needs signal just like a phone does.

If it is an Original SimpliSafe, the fix may be hardware rather than a reset

This is the one cause on the page that no amount of restarting will clear, and it only affects older systems. SimpliSafe's Original-system article carries a warning the Gen 3 article does not: if you bought your system before December 2019, you may need to upgrade the cellular module inside the base station. If the reset above does not resolve it, SimpliSafe directs you to contact support rather than continuing to troubleshoot.

The Original light chart points at the same place from the other direction. Intermittent red blinking means no cellular connection, and SimpliSafe's own footnote on that row says a base station reporting no cell connection may need its cellular module replaced. So on an Original system, a red blink that survives a reset is a hardware conversation, not a network one.

The other Original-only fault is mechanical and free to fix. Solid red means the SIM card is not seated properly. SimpliSafe describes the fix precisely: open the plastic card-holder door on the bottom of the base station, slide the SIM fully into place with the gold plating facing the module and the chipped corner in the bottom left, then swing the door shut against the module and slide it left to lock. There is also a red motherboard light, visible only with the cone removed, which means the module itself is not installed properly.

SimpliSafe base station keeps beeping: the three-tone beep and the flashing yellow light

If your base station keeps beeping, the usual reason is the Trouble Signal rather than an offline error. If your base station is emitting a three-tone warning sound every minute with a flashing yellow light, that is not the offline error. It is the Trouble Signal, introduced in base station firmware 2.10, and SimpliSafe says these changes are part of the UL-985 Standard for Household Safety and may be required where you live depending on local law.

If the beeping is coming from a wall keypad or a panel in a closet rather than a SimpliSafe base station, this page does not apply: see what an alarm beeping every few minutes means.

SimpliSafe lists what a Trouble Signal can mean. Only one of them is the error this page is about:

  • A base station battery failure.
  • Components not responding, or marked offline in the app.
  • Smoke, CO, or combined Smoke and CO detectors reporting a malfunction or low sensitivity. SimpliSafe asks you to contact them directly for this one.
  • A smoke, CO, or Smoke and CO detector whose tamper switch is not held down.
  • A "No Link to Dispatcher" error reported by the keypad.
  • Detected RF interference.

The warning cannot be dismissed until the underlying issue is fixed, but SimpliSafe does let you modify or disable the Trouble Signal and the Trouble Light in system settings. That option is genuinely useful if the noise is keeping a household awake while you wait for a support appointment. It is worth understanding what you are switching off first: three of the six things on that list concern smoke and carbon monoxide detectors, so the Trouble Signal is, some of the time, the only local indication that a life-safety device is not working properly. Turning it off does not fix anything on the list, and if the UL-985 requirement applies where you live it is also the feature your local rules are asking for. Silence the sound if you need to sleep; treat that as a pause, not a resolution.

How to turn off the SimpliSafe base station light (and why it won't turn off)

To turn off the SimpliSafe base station light, switch off Base Station Light in the app or keypad settings; if part of the unit stays lit, switch off Wall Power Light too. This one has a specific answer that catches people out: there are two separate light settings, and switching off the obvious one leaves the other running.

Turning off Base Station Light (app: My System → Base Station Settings → Status Lights → toggle off → Save; or keypad: Menu → Master PIN → System Settings → Base Station Light) stops the main LED. If a light is still showing after that, SimpliSafe says it is almost certainly the Wall Power Light, which keeps the back half of the unit lit for as long as the power adapter is supplying power. It has its own toggle in the same two menus, listed separately as Wall Power Light.

If the light you are trying to clear is solid red on a Gen 3, do not switch it off. It is telling you there was a recent alarm, and it is designed to keep telling you until you acknowledge it on the keypad, or disarm and re-arm the system. Turning the LED off would hide the message rather than clear the event.

SimpliSafe camera offline or device offline: when one device drops, not the base station

If the app says "Camera Disconnected" or a single device is offline while the base station light looks normal, the fault is almost always that one device's WiFi, battery or signal, not the base station. Cameras connect to your router directly; sensors, the keypad and sirens talk to the base station over SimpliSafe's own radio. So the fix depends on which kind of device dropped.

SimpliSafe camera offline

  1. Did your WiFi change? SimpliSafe's "Camera Disconnected" article lists a new router, new network name or password, a move or a new internet provider as the first cause. Both the base station and every camera have to be taught the new network; the steps differ by camera model.
  2. Check the band and security type. The Indoor Camera, Outdoor Camera and Video Doorbell Pro need a 2.4 GHz network; only the Video Doorbell Series 2 can use 5 GHz. The network must use WPA2, WPA3 or WPA2/3 mixed mode, the network name and password can be at most 31 characters each, and SimpliSafe says its cameras cannot connect when either contains a semicolon or a backslash.
  3. Run the in-app Connection Check. In the app: Cameras tab, gear icon, choose the camera, Connection Check. SimpliSafe wants WiFi signal stronger than -55 dBm at the camera and upload speed above 2 Mbps; its requirements page budgets about 2 Mbps of upload per camera streaming at 1080p. A camera that keeps dropping is usually too far from the router or short of upload bandwidth, which SimpliSafe names as the two main reasons.
  4. Just recharged the battery? A battery camera can show "Camera Disconnected" for a while after a recharge while it checks back in with the base station.
  5. Last resort: remove, factory reset and re-add. Download any recordings you want to keep first, then remove the camera in the app, reset it using the steps for your model, and add it again. SimpliSafe notes you need to be at home with the system to do this.

A sensor, siren or keypad offline

For battery devices, SimpliSafe's offline articles start with the battery: an offline Entry Sensor, for example, "could indicate that the battery within the device needs to be replaced." The warning can take up to 24 hours to clear after a new battery while the base station checks back in, unless you remove and re-add the device. If several devices drop at once, look at base station placement first, since a base station in a cabinet or behind dense material weakens its signal to everything. The keypad is the device you use to fix the base station, so if the keypad itself shows offline, replace its batteries, bring it closer to the base station and check the base station light before anything else. Door, window and motion sensors have their own guide: SimpliSafe sensor not responding.

Why does my SimpliSafe base station keep losing WiFi?

A base station that drops WiFi again and again, with "WiFi lost" and then "restored" entries in the app timeline, is usually reacting to the router rather than failing. Each pair of entries means the connection dropped and came back by itself. The repeat causes, in the order worth checking:

  • Band steering on a mesh or dual-band router pushing it toward 5 GHz, which it cannot use. Give it a separate 2.4 GHz network name.
  • Congested 2.4 GHz channel. SimpliSafe recommends router channels 1, 6 or 11 to reduce interference; set one manually if your router picks automatically and drops are frequent.
  • Distance and obstacles. Move the base station into open space nearer the router (see placement), or move the router.
  • The router itself restarting overnight for firmware updates or scheduled reboots, which shows up as a lost-then-restored pair at the same time each night.
  • A security setting change after a router update, such as a network with no password or a sign-in portal, neither of which SimpliSafe supports.

On a monitored plan with cellular backup, a brief WiFi drop does not by itself cut you off from the monitoring center; it becomes urgent only when the keypad shows No Link to Dispatcher, meaning WiFi and cellular are both down.

Does SimpliSafe work without WiFi or during a power outage?

Yes, within limits SimpliSafe states itself: the base station runs on backup batteries for up to 24 hours when the power goes out, and with a professional monitoring plan it switches to its built-in cellular connection when WiFi stops working. Both switches are automatic. What changes is how you control the system while it is on backup.

SituationWhat SimpliSafe says still worksWhat changes
WiFi down, power on, professional monitoring planThe base station moves to its built-in network backup and operates on a cellular network instead of WiFi.Anything that depends on your home internet, such as WiFi camera live view, waits for the router.
WiFi down, no professional monitoring planSimpliSafe describes the cellular fallback only for professional monitoring plans.Check what your plan includes before relying on the system while the internet is out.
Power outFour NiMH rechargeable batteries keep the base station powered for up to 24 hours. Within 1 minute the keypad shows "Power Outage. You are still protected", and the app logs the outage and, with push notifications on, alerts you when power goes and when it returns.To save battery you can arm and disarm only from the keypad; the app cannot arm or disarm remotely until power is restored. SimpliCam and Video Doorbell Pro live view needs those devices to keep power and WiFi; Outdoor Camera and Smart Alarm Indoor Camera live streams are not available. Recordings made before the outage can still be viewed.
Power out for more than 24 hoursSimpliSafe recommends contacting support, and says the rechargeable batteries can be swapped for fresh rechargeable ones.Never put single-use alkaline batteries in the base station; SimpliSafe specifies four 1.2V, 1300 mAh NiMH cells.

If you have been a SimpliSafe customer since 2019 or earlier, SimpliSafe says it may be time to update the network backup so the system stays connected during an outage.

"Power Outage" on the keypad when the power is on

SimpliSafe's steps: unplug the base station power cord, wait at least 60 seconds (or until the app sends another Power Outage notification), plug it back in, wait for the Power Restored notification, then arm to Home and disarm to Off to confirm the system responds. If the error does not clear, open the battery cover and check that the base station holds four 1.2V, 1300 mAh NiMH batteries rather than alkaline ones. An outlet controlled by a light switch is another repeat cause, covered in No Link to Dispatcher. For planning beyond one brand, see our cellular backup and power outage guide.

When it's not the base station

A few situations look like an offline base station but aren't fixed by any of the above:

  • Whole-home internet outage. If your internet is down, the base station will report offline until service returns. Confirm other devices have internet before troubleshooting the SimpliSafe itself.
  • A different SimpliSafe generation. The WiFi and placement steps here describe the widely-owned Gen 3 base station. The Original system is covered separately in the light chart and the reset table above, and note that its base station has no WiFi step at all, so every 2.4 GHz and mesh-router instruction on this page is irrelevant to it. If your equipment is newer again, follow the in-app setup instructions for your specific system rather than assuming these details apply.
  • A single device offline rather than the whole system. "Camera offline" and "device offline" in the app are usually not a base station fault. SimpliSafe notes that poor base station placement, in a cabinet or against dense material, weakens its signal to the other devices and is itself a cause of sensors and cameras going unresponsive, so start with the light, then use the camera and device offline steps above, and for door, window and motion sensors see our SimpliSafe sensor not responding guide.
  • Account or plan lapse. Some app features and monitoring depend on an active subscription. If notifications stopped but the hardware seems healthy, confirm your plan is current before chasing a hardware fix.
  • A genuinely failed base station. If it won't hold power or connect after a clean reset on known-good WiFi, contact SimpliSafe support; base stations are covered under warranty for a period after purchase.

Rethinking the setup rather than just fixing it? If it is a single sensor rather than the whole system that dropped, see SimpliSafe sensor not responding: fixes that work. On a Ring Alarm instead of a SimpliSafe? Our Ring Alarm troubleshooting guide walks the base station, sensors, and keypad the same way. If constant WiFi drops have you weighing whether a self-monitored system is right for you, our monitoring guide lays out what professional monitoring actually adds. If you inherited this SimpliSafe or any other alarm with a home, start with what to do with an inherited alarm system. And whatever system you run, our home security checklist covers the low-cost basics that make any alarm work harder.

If the base station keeps dropping and you are weighing replacement rather than another fix, the honest comparison is a cost one: what SimpliSafe and ADT each cost over five years, and which systems run with no monthly fee if the subscription is what you want to stop paying. Worth saying plainly: most cases on this page are a router setting rather than failing hardware, so work the steps above before spending anything.

Common questions

Why is my SimpliSafe base station red?

On a Gen 3 SimpliSafe (bought 2018 or later), a continuous red pulse that turns solid after 1 to 2 minutes means there was a recent alarm, and the light stays solid red until you clear the warning on the keypad or disarm and re-arm. A slow red pulse once every 8 to 10 seconds means a minor system error, such as radio interference, and the keypad shows the details. On the Original SimpliSafe (2017 or earlier), solid red means the SIM card is not seated properly and intermittent red blinking means no cellular connection.

How do I get the red light off my SimpliSafe base station?

Press Off on the keypad to disarm, press the keypad screen toward the warning symbol, and select Clear on the error that appears. SimpliSafe says this clears the keypad message and resets the red LED. If the red light persists, power cycle the base station. Turning off the Base Station Light setting only hides the light; it does not clear the alarm event.

Why is my SimpliSafe base station flashing red?

It depends on the rhythm. A continuous flashing red for 1 to 2 minutes is a recent alarm and will turn solid red. A slow flash with 8 to 10 seconds between pulses is a minor system error, not an alarm; check the keypad for the cause. On an Original system, intermittent red blinking means the base station has no cellular connection, while a single red blink just means it sent a signal.

What does No Link to Dispatch Center mean on SimpliSafe?

SimpliSafe's wording is "No Link to Dispatcher". On a monitored plan it means the base station has lost both its WiFi and its cellular connection and cannot reach the Monitoring Center. On Self Monitoring with Camera Recordings or Basic App Control it means the base station has lost WiFi only. Work through power, WiFi (including the 2.4 GHz requirement), placement and the reset for your generation.

Is a red light on my SimpliSafe base station the same as it being offline?

Not on a Gen 3. Red means a recent alarm or a minor error. An offline base station is reported by the keypad and app, and No Link to Dispatcher is one of the causes of the Trouble Signal, which shows as a blinking yellow light with a three-tone sound. On an Original system, intermittent red blinking does mean a lost cellular connection.

Why does my SimpliSafe camera say offline?

Usually because its WiFi changed or weakened, not because the base station failed. Cameras need a 2.4 GHz network (only the Video Doorbell Series 2 can use 5 GHz), WPA2, WPA3 or mixed security, and a network name and password of 31 characters or fewer with no semicolons or backslashes. Run Connection Check in the app: SimpliSafe wants signal stronger than -55 dBm and upload above 2 Mbps. If that fails, remove the camera, factory reset it and add it again.

Why does my SimpliSafe base station keep losing WiFi?

Most repeat drops come from the router: band steering pushing the base station to 5 GHz, a crowded channel (SimpliSafe recommends channels 1, 6 or 11), distance from the router, or scheduled router reboots. "WiFi lost" followed by "restored" in the timeline means it dropped and reconnected by itself. Give it a dedicated 2.4 GHz network and move it into open space nearer the router.

Does SimpliSafe work without WiFi?

Yes, on a professional monitoring plan. SimpliSafe says the base station switches automatically to its built-in network backup and operates on a cellular network when WiFi stops working. SimpliSafe describes that cellular fallback only for professional monitoring plans, so check your plan if you self-monitor. WiFi camera live view still needs your internet.

What happens to SimpliSafe in a power outage?

The base station switches to four NiMH rechargeable backup batteries that SimpliSafe says last up to 24 hours. The keypad shows a Power Outage warning within a minute, and you can arm and disarm only from the keypad until power returns; the app cannot arm or disarm remotely during the outage.
