WELL-KO-KO PA-441B WiFi Smart Smoke Alarm: Works with Amazon Alexa and Google Assistant
Meet the Tuya WiFi Smart Smoke Alarm—your home's new guardian angel, minus the wings. It's not just smart; it's practically clairvoyant, sending real-time alerts straight to your phone because guessing games are for trivia night, not safety. And yes, it plays nice with Amazon Alexa and Google Assistant, so you can boss it around with your voice or the Tuya app. Because sometimes, you're just too cozy to move.
Why you'll love it (or at least appreciate it deeply):
- Ever wished your smoke alarm could chat with your smart lights? Now it can. Seamless smart home integration is here.
- Real-time alerts mean you're always in the loop, even if you're out buying more smoke alarms (because why stop at one?).
- Loud? Check. Reliable? Double-check. This thing won't let a little interference stand between you and peace of mind.
- Installation is a breeze—no wires, no fuss, just stick it up and forget about it (until you need it, of course).
