Hello,

For the home automatization i want to control the heating system with a Raspberry Pi. I can control it by using a relay but i want to use to opentherm technology for using the heating with modulation.

Is the opentherm Gateway a product i can use? Can i connect it to a raspberry pi and send and receive data to the heating system?
The heating system i have is a Nefit ProLine HRC 30 HR CW5

I am a programmer but i haven't done anything with opentherm yet.

Thanks for your help!

From the manual I get the impression that the Nefit ProLine HRC 30 HR CW5 doesn't support Opentherm. So then the OTGW will not be able to work with it.

You will need an EMS-OT converter to talk to that boiler through OTGW. Available from EUR 50.-- upwards.

grtz,

Thank you,

If i buy the EMS-OT converter, can i modulate the boiler like this connection:

Raspberry PI -> OpenTherm Gateway -> EMS-OT -> Nefit Proline HRC 30 HR CW5

So i can make a software programm that sets the temp and the boiler modulates?
Thanks again for your help!

No one knows if this works?

And do i need to add a thermostat or can i use the raspberry pi to set and receive the temperatures?

Thank you very much!
