Bosch Condens 2500 - what protocol are use? #555

Hello there,

If use this boiler with external thermostat (Tado), what protocol are we use?

The Options:

The official manual say that it EMS, but no detailed info... This issue say that is HT3 (https://github.com/proddy/EMS-ESP/issues/39)

It possible that this boiler use EMS2? Unfortuantelly EMS2 is not supported by Tado.

I don't think its EMS2 but I'm not a Bosch dealer so better call one to verify.

@vampywiz17: start terminal and type watch on 8, if you see a type-id with 3 digits it's ems+, but i think most boilers are ems or HT3. (i.e. the 3. number => (0x34) in Boiler(0x08) -> (0x00), (0x34), data: ...)
