Hallo Joost, sorry for my late reply! I'm also a beginner in perl (actually this was the first time that I've coded something in perl ...!) and to be honest I don't know yet how to make a module for fhem. At the moment my script reads the setpoints for the radiators by reading the log files of fhem,...

Hallo Arno, sorry for my late reply. In short and high level: I have an opentherm converter which I purcased from http://www.homewizard.nl/, to this converter I have connected the opentherm gateway from http://otgw.tclcode.com/. There is no thermostat connected to the opentherm gateway. I have fhem ...

I used otmonitor from my laptop to test if everything was working properly. It is a great program and I was amazed how accurate you made the user interface! However, for my application I have to send serial commands calculated from another program running on my raspberry pi and this is not possible ...

At this moment I have 3 rooms with FHT thermostats, a raspberry pi that runs fhem, the opentherm gateway connected to the raspberry pi.

I thought it had to be off because there are no wires for RTS and CTS on the opentherm gateway, so I still ...

Hello everybody, I'm setting up an opentherm gateway to control my boiler with a Raspberry Pi. My idea is to have a script (either unix shell, perl or python) that can send setpoints to the boiler (following the description in http://otgw.tclcode.com/firmware.html#configuration).
