Set Max CH setpoint boundaries (MsgID=49)
Hi,
How can I set Max CH setpoint boundaries (MsgID=49)? I Have a Viessmann Vitodens 100W with OTGW and on-of thermostat, I can't set max setpoint higher than 39 C, because the boundaries are 39 20. THX

Viessmann Vitodens 100 problem
Hi,
I ordered OTGW and I try to use with Viessmann Vitodens 100 and on-of thermostat. I cant see any data in NodeMCU's IP. And when my thermostat is on, the boiler heat the water to 80 celsius, can't set the temperature (neither Otmonitor, nor manual) thanks for your help!
