I recently had a Generac Synergy generator installed, which went smoothly, however there was no good way to get the Y wire from my thermostat to the transfer switch and back in order to allow the transfer switch to cut the y wire signal.
It seems like this should be able to be done wireless as 24v DC is available in both the transfer switch and at the thermostat with some kind of a wireless relay, but I have had trouble identifying a suitable product, so I'm not sure if there may be some problem with my thought process.
Is there a good way to have a wireless transmitter in my transfer switch which can wireless cause a 24v relay to cut power on the y line either at my thermostat or at my AC unit? If not, what are the problems such a system would encounter that prevent it from being reliable.
