I am going to replace our old Junkers gas boiler and I am trying to find out which of them are actually smart enough to be connected to HA. It’s pretty daunting tbh. If there is any integration, it’s usually only via their Cloud portal (which goes against my principles of local and open-first, but better than nothing). Is there anything specific I should look at or does anyone have any recommendations?
From the options I have, I consider the following gas boilers:
- Vaillant VU 25CS/1-5 ecoTEC (something like this?, also through cloud)
- Viessmann Vitodens 100 W 24 kW (probably with Vitoconnect and their API, I found this: Viessmann Component - #343 by adorobis)
- Buderus Logamax plus, GB122i-24 (24 kW) + Logamatic RC310 (no idea if/how)
- Junkers ZSBR 28-3E (I guess with some EasyControl controller? does it have opentherm?)
