Hi gohan.
Oh, I thought it was a mysensors thing. That there's anywhere a declaration for the value name.
I'm new in house automation and still have a lot to learn.
I will ask in FHEM Forum. Thank you.

Hey everybody,

I built a soil moisture sensors with the YL-39 and YL-69. I'm using FHEM as Controller. The name of the value from sensors is present as "level". I would like to rename it to "moisture level".
Can someone explain how I can change the valuename ?

Hi,
I'm new in MySensors and build this Dimmer - LED with and without the rotary encoder which works fine.
Now I would like to decouple the rotary encoder as a battery powered "standalone" sensor which is (in best case) connected directly to the LED-Dimmer. Furthermore the decoupled rotary encoder should be always in sleep mode until the rotary encoder awake the arduino.
Is that possible ? I'm just stuck to seperate the code for the rotary encoder from the led-dimmer code.
Thank you in advance.
