I have hydronic air handlers are heated by a fuel oil boiler. I have Central AC using those same air handlers. I wanted to use a Wi-Fi thermostat but I do not have any leftover wires in the wall. My understanding is that I need one more wire to power the thermostat. What are my options? Thank you

    You can use Honeywell Redlink, they communicate wirelessly to a gateway. Does need a receiver and some wiring at boiler. Tekmar has something similar Or a common maker. Or just pull some wires

    Redlink is so good I'm using it and I have 8 wires run to my stat. The Prestige only needs two but is probably the best tstat out there.
