I finished unpacking from my move yesterday, with only a few chores left (like finding a home for all the little things in my office that have taken over my desk). Shortly after finishing, I took out the trash, and started to wind down. Then I noticed my house getting warmer.
The previous owners had an Ecobee thermostat, which, because I'm on the Google ecosystem, I will replace with the Nest thermostat that should arrive today. I noticed that this Ecobee had a very strange reading: 63°F. And falling. And running the heater full-blast to try getting the temperature back up to normal.
Once it got to 60°F I shut off the heating system. Other thermometers in my house showed 20–21°C and steady. Plus, if it really had been that cold, I would be shivering or at least wearing a sweater.
When I woke up this morning, the Ecobee told me the house was 44°F—just a degree or two warmer than the temperature outside.
Then I realized what had happened.
As with the Nest thermostat, Ecobees can use multiple small sensors throughout the house for zone coverage. One of those Ecobee sensors was now in a trash bag in the dumpster by the alley, and broadcasting with sufficient power that the main thermostat thought the guest bedroom was freezing cold.
So the heating system is still off, which is fine because (a) Parker has two fur coats and doesn't mind and (b) I can see from other sensors that the house is still around 19°C, which is perfectly comfortable for both of us.
All of this is part of the unintended fun of home automation, and of moving.
