Thanks for the details. I’m no electrician so maybe I don’t understand my setup correctly.
At the ceiling I have black,white,clear and red. The red was not originally used for the fan. The original wall plate had two switches. The first one was a regular light toggle switch where the red wire was the load (presumably) to the ceiling fan which had no light. Therefore the switch did nothing. The other wires, including the black load wire, are run to the ceiling to control the original ceiling fan. So, I’m not sure if I have 2 cables but I know I only have 4 wires at the ceiling.
Seems to me it should work. I have 1 wall switch that will energize the red wire (turn on the light) and another switch that will energize the black wire (turn on the fan) and they both share neutral and ground. Will that work or do I need the relay like you did? The “light” switch I purchased is: GE Z-Wave Wireless Lighting Control Dimmer Switch. So is this similar or the same as the Aeon dimmer switch you used?
I already installed ChadK’s very nice driver code you mentioned and started to write a little smartApp to connect my Nest and the Fan together.
Thanks for the help.
Edit: I found an image that shows the way I think it will work. My switches are obviously the GE fan and dimmer switches instead of the toggle but the wiring will be identical to this:
