Re: Unknown-DataId Control Setpoint

I don't have a log file from the moment where the problem starts. This because it seems to be arbitrary when it happens, although it happens almost every day since a few days. I thought I had the real cause of the problem, but the error already rises after 2,5 hours. I now do have the complete logfi...

Unknown-DataId Control Setpoint

Sometimes my heating system stops functioning correctly. I investigated the problem and it turns out that the OTG responds to the thermostat that the boiler does'nt understand the control setpoint ID (ID 01). I don't know the exact cause of this behaviour but I guess that the boiler once responded w...

Re: Opentherm Gateway assembly problem

I just soldered everything onto the PCB (which I yesterday received from Lennart). But the problem of a flashing backlight still remains. Is there maybe something wrong with my components?
Before soldering everything to the board I measered all resistors, so I'm sure they are all correct.

Re: Opentherm Gateway assembly problem

Re: Opentherm Gateway assembly problem

I made a small movie of the thermostat, maybe this helps understanding the problem

Re: Opentherm Gateway assembly problem

That battery is also in the manual. According to the manual the date and time is preserved. But this is also n...
