I've just has an Atag iC Economiser 35 installed which has an Opentherm interface.
I don't want to buy any off the shelf controls as I've written an open source BMS framework for some projects I'm doing with some universities.
I'd like to be able to turn the space heating on and off, and set the flow temperature from the Pi. I'd also like to able to set the domestic hot water temperature, though this is less important.
I see there is a gateway kit available from https://www.kiwi-electronics.nl/openthe ... it?lang=en with a pre-programmed PIC.
Am I likely to be able to use this kit with the standard firmware to interact with the boiler space heating ?
Are there any other interesting features or monitoring of the boiler I can do over this interface ?
Many thanks, J/.
