Can any one recommend the best leak detector (non cloud) that integrates with HA?

I have a couple of these Zooz Z-Wave water detectors. They were recognized by zwave2js, and easy to set up and test. My only issue is that I get triggers from them whenever the Z-Wave network changes - like, when I add new devices, I get an alarm from them.

They're tiny - like the size of an old box of (matchstick) matches. If they were cheaper, If put one under every sink.

I had a similar issue with other zwave sensors. With a little help I was able to refine my triggers so that my automations only run when they go from an “off” state to an “on” state. Before that they’d trigger from a “none” or “unknown” state, which is what happens when HA or zwave2js restarts.

Ah thanks! These are the only ZWave I have that does this - I'll check that!

Here's the relevant part of one of my automations. It's for a light sensor I have attached to my washing machine:

trigger:
  - platform: state
    entity_id:
      - binary_sensor.washer_light_sensor_sensor_state_any
    from: "on"
    to: "off"
