[shelly] Brightness cannot be set to zero

[uli5961]

Hi ,
there seems to be a minor bug with shellyplusrgbwpm, channel brightness:

In thing definition is brightness AUTO ON set up.
When i set brightness with slider > zero, RGBW stripe is switched on.

When i try to set brightness to zero, stripe should be switched off, but value cannot be set to 0, value 1 is possible.

( Slider indicates zero but in Shelly webinterface value is > zero)

So stripe cannot be switched off.

Tried to set value zero in rule (Shelly_Plus_RGBW_Helligkeit.sendCommand('OFF')) , didnt work, any other value > 0 works.

I am experiencing the same issue. As I use only the first channel of the shellyplusrgbwpm, As a workaround, I had to register it as shellyplus10v, where it works correctly.
