Hello,
I have a evohome system that works quite well with a BDR91 to a Worcester Greenstar 30si combi boiler. Unfortunately, the Worcester uses the EMS protocol for modulation rather than OpenTherm.
I wonder if there is such a thing as an EMS to OpenTherm gateway, and (upon Googling), I have found this: https://en.robbshop.nl/ems-ot-opentherm-converter-nefit
It is described as: The Nefit / BOSCH EMS IP Converter is capable of converting OpenTherm communication Nefit / BOSCH communication protocols. This allows you to OpenTherm thermostat connected without any problems to your Nefit or BOSCH HR boiler.
Any ideas if it will work?
