@Gargron@mastodon.social listen to the plumber if they're willing to offer advice

@Gargron@mastodon.social good ol` HomeAssistant for some reason not an option?

@Gargron@mastodon.social How about something like https://www.ebay.co.uk/itm/395345543471 and https://www.ebay.co.uk/itm/178227178808

“What you’re asking for doesn’t exist, you should get a dumb thermostat” is also a valid answer to my question, just to be clear. I don’t know what I don’t know.

@Gargron@mastodon.social It seems to be out of stock currently, but the DIYless OpenTherm V3 is BY FAR the best nerd-friendly option. I have one and it's fantastic. It talks OpenTherm to the boiler and connects via WiFi, pushing all sensor data to your local MQTT broker, from where Home Assistant can interact with it. It supports external temperature sensors, via Bluetooth or MQTT. No cloud dependency at all, fully local and made in Europe. https://diyless.com/product/opentherm-thermostat3

@Gargron@mastodon.social get a normal thermostat. What does OpemTherm have to do with anything? Do you already have an automation system? I assume not?

@Gargron@mastodon.social I had a success automating basically anything in my house using Shelly products (https://www.shelly.com/). All of them are VERY configurable, support various protocols and can work completely independently from any cloud or outside internet.

@Gargron@mastodon.social I can’t see anyone recommending Tado but I’m in my fourth home where I’ve installed it. (In the first two I literally installed it myself and still do all the TVRs).

@Gargron@mastodon.social I’m shocked nobody in this thread has suggested installing Linux.

@Gargron@mastodon.social I also have home assistant etc but I use Tado wall thermostats and radiator valve thermostats. Work well, the app is fine, no fuss to install and supports OpenTherm.

@Gargron@mastodon.social Opentherm seems to be far from openness: https://www.opentherm.eu/opentherm-protocol/how-to-use-the-protocol/ Protocol is available only to members. This is the reason why I do not want "smart" appliances in my home... However in the "products" bottom link there are links to thermostats, maybe you can find one viable.

@Gargron@mastodon.social I use Plugwise's Emma with Home Assistant, via zigbee2mqtt: - https://www.plugwise.com/en/product/emma-wired-pro/ - https://www.zigbee2mqtt.io/devices/170-01.html It exposes all its functionalities via ZigBee, so you can adapt it to any ZigBee setup. It doesn't do scheduling by itself, though.

@Gargron@mastodon.social @Fizzfizzpopop@veganism.social well, it’s not helping you, but this has reminded me that I should do something about the bricked gen-2 Nest thermostat we have… And it turns out that there’s a OSS firmware and self-hostable server combo I can spin up 🙌 https://nolongerevil.com/

@Gargron@mastodon.social I use a z-wave thermostat at my place and it works fine. I just got whatever looked like it would work. I've bought a couple no problems. I replaced the existing dumb thermostats myself.

@barnesmaurice@mastodonapp.uk 2026-11-06 23:18
@Gargron@mastodon.social What are you wanting it to do? Schedule on/off times for heat, schedule day/night temps, or schedule hot water? How many thermostats? Does your boiler have weather compensation and do you know your home heat demand?

@janbart@mastodon.social 2026-11-07 07:34
@Gargron@mastodon.social Maybe the Plugwise Anna thermostat is something for you? https://www.plugwise.com/en/smart-thermostats/
