Hi Jochen, no need for a terminating resistor. In my case (Raspi with PiCAN2 board) it is working without.

And if you want to use openHAB, sou should use this fork: https://github.com/Spanni26/pyHPSU This repo is not maintained anymore.

Very cool, with this we will be able to start water heating from remote. Thank you so much!

That container part is already done: https://hub.docker.com/r/pdcemulator/pyhpsu/ :-)
