i am using openHABian with openHAB 2.5.5-1 on a RaspberryPi 3. I use the openHAB Android App Version 2.12.1. I use a RGB-Light-Bulb with tasmota-Firmware on it at the version 8.3.1.
I want to control the tasmota RGB-Light with the mqtt-binding. So i have configured a generic MQTT-Thing in PaperUI and added a Color Value (Hue,Saturation,Brightness) Channel to this Binding. The following picture shows the configuration of this channel:
My items definition:
Color DG_Wohnen_KugellampeRegal_Farblicht "Regallampe" (gTimeclock)
My sitemap definition:
So the controlling of the light through the Colorpicker at the Android App works fine. I can switch the light on and off as well i can controll the light color. The return channel over the MQTT State Topic and the Transformation is working as well!
But i have one Problem:
If i switch off the Light with the OFF-Button of the Colorpicker, the light turns off and the Hue and Saturation Value stays at the old value, only the Brightness goes to 0. If i turn on the light with the ON-Button of the Colorpicker the Brightness-value goes back to the defined Initial Brightness and everything works as expectet.
BUT if i check the actual color settings during the off-state by pressing the Colorplate (middle) button of the Colorpicker, the Hue and Saturation values are reseted to zero!
Does anybody else have this behaviour?
