You can accomplish this with the existing switches and an Enerwave ZWN-RSM2 device using a custom device type and SmartApp . This device is not officially supported by ST, but I am using 5 of them in ceiling fan canopies.
Here is some more info
I purchased a ZWN-RSM2 with the hopes on using it in locations that only have 1 hot wire in the ceiling where I’m trying to control fan and light independently. I’m only concerned with on/off on each load as that is the best I’ll get with device types available currently. Without spending over $200 per location. (total of 7 locations)
I have been struggling for a few days looking at code searching, reading learning but I just don’t know how to get started.
I was able to get this device hooked up correctly (I have it in the fan canopy rather than the switch)
I can toggle load 1 via app and via manually trigger at the device, I cannot toggle load 2 via the ST app because there is no device type to handle the request. I can toggle it via the device itself.
