I use the Tuya local integration for my stadler form dehumidifier since a few month.
Since the last update I made, i can’t switch on/off the fan with the switch and the button below the fan percentage.
Setting the fan to 0% will switch it off.
I’ve had the same happen. Tuya lights were a problem in 2025.0 but were fixed in 2025.1 but now the fans are not working for the turn_on action. Setting a speed works but isn’t easy. Hoping that 2025.2 is just around the corner with a fix!
