I already read this previous topic dealing with classical in-wall rotary dimmers and the Fibaro dimmer2 module, but I think the following combination would work better. Your advice would be very much appreciated. The RGBW dimmer (FGRGB-101 / FGRGBWM-441) accepts 0-10V analog voltage input to control 12/24V DC low voltage lamps (LEDs or halogens): 1/ Can a cost-effective classical 0-10V rotary dimmer pilot the RGBW module which would then dim the lights accordingly to the input rotation? Like this one for example: 2/ If it works that way, how would the knob rotation of the 0-10V potentiometer behave with the direct control of the RGBW module from the Fibaro interface on a computer or mobile device? Suppose you have turned the potentiometer half the way to dim the lights up to 50%. Then you open the Fibaro app and switch off the lights. Do the lights switch off? If they are switched off, the potentiometer is still at 50%… What would happen then when you turn the potentiometer again? 3/ To prevent this apparent weird behavior, I looked for 360-degree (i.e. continuous rotation with no stop) optical or Hall effect absolute rotary encoders with 0-10V analog output, as a replacement for classical potentiometers: But in this case while the voltage varies linearly according to shaft rotation from 0V/0° to 10V/359° (1 turn) it also suddenly drops to zero at the beginning of the second turn (the voltage drops from max. 10V at 359° to 0V at 360°, just one degree further) like this: This graph is for 0-5V but 0-10V acts the same way. Not very handy for lights. It would have been more useful if the voltage stayed at maximum value of 10V after 360°. 4/ I then searched for incremental rotary encoders instead of absolute rotary encoders, but it seems an incremental version with 0-10V analog voltage output doesn't exist. Your thoughts?

Hi, Is there a way to associate a RGBW controller (FGRGB-101) as a master, with a Dimmer 2 module (FGD-212) as a slave, either as a Z-Wave direct association or with a LUA script on the main controller? My goal is to dim LEDs connected to 110-240V AC, with a distant low voltage RGBW module. LEDs are connected to a Dimmer 2 module. 30 feet away, a 12V DC RGBW controller interprets the variable output of an analog sensor. I'd like to dim the distant LEDs accordingly to the level the RGBW module would set if it was directly connected to equivalent 12V DC LEDs. In other words, can the dimming level information of an RGBW controller be passed to a Dimmer 2? I know that two RGBW modules can be synchronised, but I don't know if an RGBW module and a Dimmer 2 module can be synchronised.
