Ok, did you play around with voltage reference yet?
You can submit such a command via either OT monitor or domoticz. In my case I had to set on VR=1. Probably caused by the too low capacity of the OTGW transformer which I will change to more powerfull one. see other posts in this forum.

VR=level
Voltage Reference - Change the reference voltage used as a threshold for the comparators. This configuration option is stored in non-volatile memory so it will persist even if the gateway has been powered off. The level must be specified as a single digit according to the following table:
0 1 2 3 4 5 6 7 8 9
0.625V 0.833V 1.042V 1.250V 1.458V 1.667V 1.875V 2.083V 2.292V 2.500V
The normal value is 3.
Examples: VR=3, VR=4

I have tried that but I set it back to VR=1.
and if look at data from the boiler I see nothing but the thermostat does send data
