I got a flood detection ST812 connecting to PI via Z-Wave stick.
HA identified the device and I can see it in the front page. The device has 2 states: 0 and 255 (indicating flood). When I put it in water the state in the front page changes to 255 and when I remove it from water the state is back to 0.
Still the system just trigger the situation of returning to 0. In the logbook I don’t see the state change to 255 even though it change in the front page.
Any idea why?
