Røgalarmmonitor

Setup took maybe ten minutes and now I get a phone alert the second my old detector goes off, even when I'm across town. The fact that it works with my existing alarm instead of making me replace everything is what sold me.

It listens for any standard detector, so you don’t have to rip out your existing setup or buy a whole new system. I tested it by triggering my kitchen alarm, and the notification hit my phone in about three seconds—that instant peace of mind is honestly priceless.

The instant phone alert came through before I even got out of the kitchen chair, and that's exactly what I needed with my aging detectors. It listens for any standard alarm, so I didn't have to replace a single unit—just plugged it in and it's been flawless all week.
