I like to create a scen to turn on/off all my lamp but i can only add one, when i try to add more its replace the fist one...it there a bug or what wrong?
I have the lastet firmeware.
yes, there seems to be that limit of one actuator, although the UI implies otherwise. What I did is add a scene for each individual lamp, so have your scene for the RF trigger to turn on lamp A, and another scene for 'if lamp A is on, turn on lamp B', 'if lamp A is off, turn off lamp B', and 'if lamp A is on, turn on lamp C', ...
A bit tiresome, but it works
