@Gargron@mastodon.social Do you have a local home assistant setup? You can probably find a thermostat with Zigbee/Z-wave/Thread/Matter and control it locally and enable remote access (if desired) via tailscale or similar.

I’m getting some promising leads from this thread but also a number of frustrating responses. If I could get the answer from googling or reading the HA forums or subreddit, I wouldn’t be asking. I’ve already done all that. The plumber usually installs Hive. The boiler manual suggests Halo. Both of those seem to require using the cloud. The old boiler was plugged into a Honeywell that didn’t have a temperature sensor. If you don’t know, just move past it.

@Gargron@mastodon.social note that I can't vouch for this cause I haven't gone down that route yet (I know someone who runs a Zigbee Bosch thermostat at home which sorts that for him, but not opentherm). However I've came across this before. AFAICT this is very much how you'd do it with a simple ESP32 micro controller and the ESPHome firmware. They even seem to have a neat controller for the wall, but you can probably even quickly cook up the DIY version on the cheap just to test. https://diyless.com/blog/esphome-opentherm-thermostat

@Gargron@mastodon.social I will say that we insisted on a dumb, physically wired thermostat when we upgraded our heating five years ago, and I sort of regret it. When we've been out all day, it WOULD be nice to tell the heating system to get started half an hour before we arrive. Trade-offs.
