I have a fan/light with two separate switches. The switch box does not have any neutrals. I know that the blue switches will work, but I do not want to take the speed limitation associated with the non neutral install of the fan switch.
My thoughts are to use the canopy fan module, control the fan with it, use the current fan switch wiring to hand a neutral back to the switch, with that I can run a neutral type wiring schematic for the lights using a standard blue dinner switch, hook up another blue switch to control the fan via zigbee and the canopy module. I would wrap the wires for the light wires in the canopy module to prevent any issues.
Am I thinking correctly, or are there issues I’m not considering. The advantages I can see is I maintain control of the full fan speed, can use blue switches in that box without a bypass. There is an additional three way switch in the same box, wired as a California 3 way.
I’m a little confused about your wiring configuration. You stated that you have two switches, one for the fan and one for the light, and both are non-neutral? In other words you have two switch loops?
If that is the case, does that mean exclusive of the ground you have four conductors at the switch box?
It’s a 3 gang box with 3 switch loops. 7 conductors (4 for fan/light, 3 for 3 way switch). 1 fan/light has two of those switch loops, so light and fan can operate independently of each other. This is what I’m looking to setup primarily. The other switch loop is part of a California 3 way setup 3 conductors.
Also, I think I didn’t completely answer your question, this is wired with standard nm Romex, so 2 conductors and a ground. The house was built in the late nineties, but in my state the code lags behind quite some time, so no neutrals were required at the switch yet. So switch legs and California 3 ways throughout.
So I can use the standard blue switches and fan switch here, but I don’t want to lose the full speed control on the fan.
Got it. Interesting, actually, because I would have thought that with a California 3-way you would have had THHN in conduit. But I digress.
Leaving that 3-way aside, I don’t think you need a canopy module. If I understand correctly, you have a hot/neutral that originates at the fan/light. Two switch loops each with 2-wires control the fan and light independently.
This is sort of the direction you were going. Rewire at the fan to send a hot and neutral over one of the 2-wires. Now you have a neutral config at the box. The other Romex has 2 conductors. Use one for the fan load on an Inovelli Fan Switch and the other for the light load on an Inovelli 2-1 dimmer for the light.
This gives you independently switched load conductors back at the fan/light, so no need for a canopy module.
I think so.
I’ll select one of the switch legs, pull the black label off in the switch box and fan box, hook it to the mains power in fan box. Use that to pig tail into the neutral terminals on the two blue switches (dimmer and fan) in the switch box.
The hot would then pig tail into the line terminals on the switches.
The other current switch leg, the neutral wire would remain labeled hot, used to return power to the lights, hooked into load terminals on the light switch The other hooked into the load terminals on the fan.
Back at the fan, the hot wires would be disconnected except for the one running to the switch box (line). The two conductors from the other switch leg would remain labeled hot, and one would go to the lights, one to the fan. Neutrals to finish the circuit in the fan canopy.
Sorry for basically repeating what you said, but I wanted to make sure I got it.
I’m kind of surprised I didn’t think about it, as it is a graceful solution. Thank you much!
