I have a Honeywell Evohome Wifi system and Remeha Tzerra Ace boiler connected with BDR91A1000 relay module.
I'm trying to change this relay module to the R8810A1018 OpenTherm bridge hoping more optimal boiler operation.
Can someone point me to a service company or a web site where I can learn if this is possible at all and can this be done by myself?

Re: EvoHome+OpenTherm R8810A + Remeha Tzerra Ace
Have you been able to use R8810A1018 with Remeha Tzerra?
I am using the same BDR91A1000 with another boiler.
I will soon change the boiler with Remeha Tzerra ACE 24.
I work for a HVAC company and we install Remeha boilers too.
My colleagues haven't been able to connect opentherm thermostats with Tzerra ACE but they always installed them in ON/OFF mode. I requested to Remeha but they couldn't confirm.
If you want to try, I suggest you to order R8810A1018 from Amazon and send it back if it won't work.
I recently found this link https://plugwisehelp.freshdesk.com/en/s ... tzerra-ace
which is worth a try.
I even found this, if you are willing to buy etwist with its gateway https://plugwisehelp.freshdesk.com/en/s ... -the-adam-
