Worcester Bosch EMS2
It appears Tado is able to work with older Worcester Bosch Boilers with HT-EMS. Possibly some others Bosch ones with EMS+ ?
It will also work on Relay (R01), On/Off Mode, but this will NOT modulate the boiler.
All new boiler installations in the uk have to confirm to EnergyPlus Regulations. This means having some of Weather Compensation,Load Compensation, or smart controlling. Tado conforms as the latter one only. so no real Modulation control on the boilers.
EU however legislate that boilers have OpenTherm, which is a way better approach.
Newer Worcester Bosch boilers (2000,4000,8000,8000+) have EMS2. Which has been the case for a number of years now.
Tado doesn't support this, even though EMS2 has been around and used for over 2 years.
So for me, it's more important to have a control system that can modulate the boiler to gain the energy efficiencies.
Without this support it means I now have to Dump Tado after so many years.
I'm going to have to switch to EasyControl and ETRV's, in order to have a properly functioning modulating heating system.
It's genuinely sad for me, as I loved the Tado platform, which met so many of my requirements.
Please implement EMS2 support!
In fact I looking to update to Tado X, but this lack of EMS2 support is a deal breaker.

Nefit makes an OpenTherm to EMS protocol converter. This mean that you should be able to use the Tado thermostat to control the Bosch boiler. I use this converter with the Nest 3rd gen thermostat to control it. I don't like the Bosch thermostat0
