I love what you’re doing and try to support you. I like a lot about what you’ve done with your new smart thermostat. But I was shocked and dismayed that it will not work to control a zone valve. I cannot speak for the entire country, but in New England, this is by far and away the most common thermostat. Personally, I have seven zone valves and a couple of them would be nearly impossible to run a “C” wire to. So, I was really excited about your new product that does not require the installation of a “C” wire. What a shame for me (and for all of us with zone valves) that you failed to accommodate this type of thermostat. Please make it a priority to address this.
