There is nothing worse than waking up after a brief storm or a quick 10-second power flicker to find your entire smart home in absolute chaos.
Your smart bulbs are flashing full-blast in the middle of the night. Your smart plugs refuse to connect to the internet. Worst of all, your complex automations, schedules, and routines are completely broken because your smart hubs and router booted back up in the wrong order and lost their minds.
When the power cuts out—even for a millisecond—your smart devices experience a violent digital disconnect. Your internet modem takes several minutes to find a signal, your router takes time to broadcast WiFi, and your smart hubs boot up into a dark, offline network. When devices can’t find their host network instantly, they often drop their memory, glitch out, or completely reset themselves to factory defaults.
You do not have to accept this as a tax for having a modern home. You just need to keep your critical tech breathing during a blackout so your network handshake never breaks.
Here are 3 Amazon finds that keep your internet alive, protect your smart hub’s memory, and ensure your devices instantly resume exactly what they were doing the moment the lights come back on.
1. Shanqiu 74Wh Mini UPS
The power goes out for three seconds. Your smart lights forget their schedules. Your plug doesn’t respond to voice commands. Your entire evening is now spent factory-resetting devices that worked fine five minutes ago. This is a mini uninterruptible power supply that sits between your wall outlet and your modem/router. When the power dies, it keeps your Wi-Fi alive for up to three hours — long enough for the grid to come back or for you to properly shut things down. Your smart devices never lose their network handshake. They never forget they’re connected. You come home from work and everything still works, even if the neighborhood had a brownout at noon.

2. APC UPS 600VA Battery Backup and Surge Protector
Your smart home hub is the brain of everything. When it loses power, even for a second, it can drop offline, lose its memory, or force you into a hard factory reset that wipes every device, every routine, every schedule you’ve built. This battery backup plugs into the wall, your hub plugs into it, and when the power flickers the hub never knows anything happened. It stays on, stays connected, stays configured. Your lights still turn on at sunset. Your thermostat still knows the schedule. Your morning routine still works. The kind of insurance policy that costs less than one evening of screaming at a SmartThings app.

3. Tapo P210M Matter Supported Smart Plug
Your old smart plug loses power and comes back on confused — sometimes on, sometimes off, sometimes blinking and waiting for you to reconfigure it from scratch. This plug has local memory. When the power returns, it instantly resumes its exact previous state — on, off, scheduled — without needing to phone home to a cloud server first. Matter-certified, so it works with Alexa, Google, HomeKit, SmartThings, whatever you’re using. Energy monitoring built in, so you can see if that space heater is why your electric bill doubled. 15 amps, 1800 watts max, ETL certified. You plug it in, set it up once, and it remembers who it is even when the world around it forgets.
