We’ve committed to our new Nest Thermostat being on Matter, and we are still evaluating if the learning thermostat can handle Matter. It does have Thread. But just because it has Thread doesn’t mean we can run Matter on it.
So, no Apple HomeKit support ever.
Google buys nest, makes some updates, funds the company to keep making one of the best thermostat. The iconic design for this thermostat along with its learning ability is what makes this thermostat a worry & hands free device.
Now, new updates are coming only to their cheaper version which has buttons, no learnability and horrible aesthetics.
Time to switch to ecobee.
