Tuya Issue - Switch of Diivoo watervalve (Single unit) isn't working in HA

Third party integrations
1

I’ve installed my newly purchased Diivoo watervalve (Single unit) on the Tuya app (all working fine)
and it also appeared automatically into HA.
But when pressing the valve swith in HA, it jumps off after 1 or 2 seconds, and nothing seems to happen (valve doesn’t open or close)
on the other hand on/off works fine in the Tuya app itself.
any idea what could be the cause or how to solve HA setting the swith to ‘off’ after 1 or 2 seconds.

i’m on HA version
in the logbook I see frequently messages like this
