Our garage flooded last night (not the first time) and so I want to install some water sensors in the garage and basement. There’s dumb ones that look similar to a smoke detector, but all they do is make noise, which I’m willing to bet I won’t hear since I can barely hear the smoke detector in the kitchen when I’m upstairs. thats why I want a smart system so it rings an alarm on my phone as well, though if there was something with like a repeater I could install upstairs that would work too. thanks all
We’ve done this with Home Assistant (on a raspberry pi), and Zwave / ZigBee. Its been working great for years. Also allows for really customizable alerts for different things - and has been super stable.
Not very difficult to setup either - the interface is pretty polished these days!
