Z-wave dimmer remote behind existing wall switch for Hue
Hi All,
Probably some of you have tackled this issue already, but I was not able to find a conclusive answer/example yet :
My house is full of Hue, and we love it However, I would like to keep using existing wall switches as well, just for convenience purposes (and the misses Flight777), to turn lights/rooms on/off or even dim them. The problem is, Hue needs permanent power, and conventional switches and most z-wave modules manipulate and cut the power, while I just need to get a signal across to Homey so he knows what to do. A "z-wave/zigbee remote" basically, disguised as a light switch.
In one room, I solved this with a Aeotec Wallmote, however, I would like to keep our style consistent in the house and use the conventional Busch-Jaeger switches we have. For the on/off part, I recently bought some EM6514 z-wave switches, which do exactly what I need, they turn existing wall switches in a on/off z-wave remote without cutting actual power.
Nonetheless, in some rooms I want to be able to dim (or select scenes) with the wall switch as well. Recently I installed a Fibaro Dimmer 2 for a non-Hue light behind a momentary switch which does exactly what I want --> If I hold the switch it will dim the light up/down. I've been looking if I can use this module for the Hue lights as well, but if I'm not mistaking, the Fibaro module will always need a load and is not able to operate purely "signal" based, so only sending out z-wave signals for dimming without actually manipulating power. Is anybody aware of modules that are able to act as a dimming z-wave remote behind a existing switch?
Hope I explained it well, if now, let me know and I'll try and adjust!

Read the thread here:

Hue is always powered on. If Misses steps into the livingroom and pushes the switch, a Hue scene is called.
PS
Note that in the flows THAN section, I reset the switch to Off again. The triggers for the FGS-222 are "On" or "Off", not "it switched state".
Hope this is clear!
Two circuits:

One circuit:

Otherwise you miss the second switch option.
Veel succes
What I did, is I made a "counter" variable basically that sets the brightness of the hue light. With one press on the left button (double momentary switch) it will increase brightness with 10%, capping it at 100% of course
The right button will do the same but dim the light with 10% and ensuring it never goes into the negative values
So my only problem now is the very sporadic response of the light on the decreasing brightness.... I suspect this is a problem with the actual Homey Hue app and how it talks to the bridge. The only way I'm sure is to directly connect the light via Zigbee to Homey but I need to wait until that light is supported :P
