Leak sensor prevented me from some pain!
Leak sensor prevented me from some pain!
Had a leak under the sink in our kitchen. I don’t want to imagine what this would have meant on a larger scale, compared the 20€ I spent on the sensor and the 10mins it costed me to install it.
what model sensors are these? are they Z-wave? how long does the battery last?
I'm very interested in a similar setup.
Looks like an Aqara leak sensor. Zigbee - you generally won't find Z-wave devices for this cheap. They were around US$15 on Amazon when I last bought some in 2023, and a dollar or two cheaper on Aliexpress.
Pretty basic construction. There's two exposed terminals at the bottom, and when they connect electrically, it alerts. If you're clever, they can be used for a bunch of things, not just leak sensing (eg https://www.homeautomationguy.io/blog/making-my-own-bed-sensor).
I'm curious. Like what?
I have the ikea ones (using zigbee), the two aaa batteries in there last about 1/2-1 year.
While not the same as the pictured ones, I can really reccomend them.
Was going to suggest the IKEA one. Pretty decent to use and has a local speaker if you don't have any home assistant devices near by.
The door contacts are good too but I found that I had to connect them a few times before they would register on ZHA
I use the water sensors from Aqara and integrated them with a Sonoff zigbee USB stick.
