We were. I had something working with Alexa (not Siri) but we never published it. Alexa was just too hard to set up to get it working consistently. That was about 2 years ago.
I just installed an Ecobee thermostat with three room sensors, which supports HomeKit if I can figure . I’m a little slow with the the fanboy technology
And his is a perfect example of useful complication worth the cost.
To minimize building costs our house was built with the air filter / air return 7 feet up the wall by the front door, and with the thermostat also by the front door.
Every 2 months I have to climb a ladder with a giant vacuum cleaner to get the surprisingly copious dust off the air return vent, descend with the vacuum in hand, then climb again to retrieve the also surprisingly dusty filter, down without ingesting too much dust since I have allergies to house dust (and severe allergies to the pampas grass that folks seem to think should decorate their yards with), and then return up with the pristine filter.
But the real nasty turns out to be that the thermostat is by the south facing front door, in an area where no one ever exists. Try as I have to balance the system so that every room cools as equally as possible when the AC is running, the control system decisions for when to run and when to stop are useless, so we have had to manually manage this thing on an hourly basis for the last 20 years.
I finally managed to convince my wife that spending $250 for a new thermostat system would improve her comfort. Well actually, I think she decided I needed a new toy and went along with my pleading.
The new thermostat system allows ignoring the temperature at the thermostat by the hot door, and using the temperature in variable combinations of motion sensor and temperature sensors. I’ve been able to get the temperature to be much better regulated, but I’m not convinced I have found the secret algorithms to improve the “wife’s comfort” yet.
I didn’t want Alexa, Hey Google, or Siri features but the company thinks we can’t live without that added complexity. We’ll see.
