I unfortunately HAD to get a stupid thermostat with wifi. can’t even get one without it now. I’d much rather have it not hooked up but I may be forced to.
How can I put this on a VLAN and block all it’s telemetry? It’s a honeywell. Can i put it on my VLAN and then use mullvad DNS to block all the shit?
“They” are saying it has to be on wifi so it can see the outdoor temp to talk to the heat pump. Bullshit i say.


My Ecobee thermostat – which is reasonably usable without an Internet connection – has one horrific flaw: the built in clock seems to drift by a minute per month, leading to my programmed schedules shifting ever so slightly.
I could have it connected to a dedicated IoT SSID and live in a VLAN jail so that it only has access to my NTP server… or I just change the time manually every six months as part of DST.
I had this problem and I just re-created the schedules in home assistant, so the schedule is just controlled by my server now.
I have an Ecobee also and have blocked its access to everything except the ntp time server using pihole
