The gateway I built is based on the same opentherm interface as in your design Schelte, but I used a different microcontroller (atmel). So I can't use your firmware. My gateway is communicating with my iSense thermostat by Opentherm protocol, and communicating with my intergas boiler by both Openthe...

I have the wired version of the iSense. But how is the slave providing this higher power level? To increase power you need to increase the voltage or increase the current. The slave talks to the master by changing the current level. So probably the slave uses higher current levels when in medium or ...
