I recently added a U-fairy Z-wave switch (double-switch) to my Homey.
This is a great addition because it does not require neutral wire the switch. You simply wire a bypass across the load and the controller in the touch panel gets the power.
I could only add it as a “Homey” generic device as specific app for U-fairy is unavailable.
I can now control it using Homey app but only for one switch, and that’s the switch with the bypass connected across.
The other cannot be controlled. What do I need for a multi-channel association? if that’s what it’s called?
