I live in the Netherlands, all our central furnaces speak OpenTherm, and still the best option is a Nest v3, it’s depressing (the device is beautiful but it should just have a local API). Perhaps next time I’ll make something like that, using home assistant you can easily turn any switch with any temp sensor into a thermostat.

TIL: > OpenTherm (OT) is a standard communications protocol used in central heating systems for the communication between central heating appliances and a thermostatic controllers.[1] As a standard, OpenTherm is independent of any single manufacturer. A controller from one manufacturer can in principle be used to control a boiler from another. However, OpenTherm controllers and boilers do not always work properly together. The OpenTherm standard comprises a number of optional features and some devices may include manufacturer-specific features. The presence or absence of such features may impair compatibility with other OpenTherm devices. * https://en.wikipedia.org/wiki/OpenTherm https://en.wikipedia.org/wiki/OpenTherm * 2.2 spec PDF: http://files.domoticaforum.eu/uploads/Manuals/Opentherm/Opentherm%20Protocol%20v2-2.pdf http://files.domoticaforum.eu/uploads/Manuals/Opentherm/Open... * https://www.opentherm.eu https://www.opentherm.eu
