I need a water level alarm. Any recommendations out there?
The float valve on my Jojo has gotten stuck a couple of times resulting in it overflowing. Want to be alerted...
If you want to invest in the Xiaomi / Aqara ecosystem and home assistant -- https://www.gearbest.com/home-smart-improvements/pp_668897.html?wid=1433363 is currently on special at R126. It's not a level detection, rather, it will sense that water is present. So you could use multiples at different levels I guess.
But there are also guys who take existing "of/off" or binary switches and modify them for water detectors. I'd take a guess that you can do something with a Sonoff if you want to tinker.
