Bug fix: false water detection for lumi_sensor_wleak_aq1

[ebaauw]

Remove state/water_bis as Xiaomi special attribute doesn't always reflect the water detected state, see #7061

Hm, removing state/water_bis causes state/lastupdated no longer to be updated. There are no other state items in the Xiaomi special attribute, and the IAS Zone doesn't support Supervision reports. Looking at the legacy code, state/lastupdated is updated from the Xiaomi special attribute.

Just doing a dummy update of state/water to the current value seems to do the trick.

Note that I haven't had a false positive on my sensor with firmware 0.0.0_0006, but I've seem plenty on my sensor with firmware 0.0.0_0004.

Interesting approach :) if it works we should give it a try.

I suppose that's as good a description as any ;-)

Been running this on my test environment for two days now, and state/lastupdated is updated as intended.

Hi Erik @ebaauw , I tried using your fix with the 2.23.0 beta branch, and my one leak sensor with firmware 0.0.0_0004 (all other 9 I have have firmware 6) is still reporting a false leak (from issue #7061). Is that expected behavior after the fix, or is something just remembering the last state? Is there a way to force the false leak go away or be cleared (i.e. update the state) without physical interaction with the sensor (i.e. shorting the leads, or having to re-pair it)?
