Can any one recommend the best leak detector (non cloud) that integrates with HA?
an esp8266 (or esp32 if you have on laying around) and a long wire. cut that in half, remove the insulation from the ends, wire one to ground and one to any output pin on the esp. detect when the pin gets shorted (basically a button activated by water). use esphome and the button input.
I’ve been using a Tuya zigbee one.
The sensor is a plastic block with a mounting screw hole, and two metal contacts on the base.
Water hits the contacts, it transmits an alert.
Sensor is on a wire, attached to the transceiver and battery, so it can be put out of harms way.Fired straight up in standard ZHA under HomeAssistant.
It cost about £14
Shelly makes some good ones, they are non cloud
If you have a zigbee network the aqara leak detector is a good option. It doesn’t require a hub, cloud or any setup. And if you are willing to wait you can get them on AliExpress for a lot cheaper than Amazon.
I have a few of the Aqara leak detectors and they have worked well.
They also have screw terminals that you can attach wires onto to extend the detection area/range. I’ve also seen people attach contact or pressure sensors to them, they are nifty devices.
