The script I posted works on my dimmer 1, see a few posts back, I have tested it.   This will dim up from the current level to 100% in 10 seconds: fibaro:call(ID, "startLevelIncrease", 10, fibaro:getValue("vaule",ID)) or simply fibaro:call(ID, "startLevelIncrease") And this down from current level to 0 (or lowest setting of your dimmer, see parameters): fibaro:call(ID, "startLevelDecrease", 10, fibaro:getValue("value",ID)) or simply fibaro:call(ID, "startLevelDecrease", 10)
