I think it would be super handy to be able to check the compatibility of my heating system before buying.
Hmm, in terms of using in standard 'call for heat' mode I suppose one could argue they are all compatible. However at least currently they are not all compatible for eBus mode.
Apparently the Vaillant VR66 controller - a new model has a different implementation of eBus which Tado have not yet been able to reverse engineer. Tado would however still work with this boiler and controller in old fashioned call for heat mode.
I would certainly like to see a way to check the 'capabilities' of specific makes and models. This would then let people see the above example problem and let them have the opportunity to choose a different make/model.
in addition the on line communication is misleading, in this web page, for example https://support.tado.com/hc/es/articles/208016186--Qu%C3%A9-interfaces-de-sistema-de-calefacci%C3%B3n-soporta-tado-
tado explains that you can control hot water in baxi boilers under digital communication protocol. I just have Tado reprogrammed for the new heater and it doesn't control the hot water
