Just yesterday, after I sent this message, my thermostat went offline
and reported that same power issue. Google then emailed me with an offer
for a free power connector. Nice, but, odd, right?
Thanks, Jake! It turned out that "install the power connector at the
zone valve" meant to connect it on the thermostat side of the zone
valve, and not after it at the boiler. I saw that but I glossed over it!
