CS, CH commands reset after 2 minutes
I am using the Nodo OTGW connected to a Viessmann boiler. Currently I am using it without a thermostat. Instead I am using the OpenHAB binding to send CS and CH commands to the boiler. The odd thing that I am experiencing is that if I send a CS or CH command value to the boiler, the value becomes active in the boiler for a while, but after about two minutes the value resets. For example if I send CH=1 the boiler becomes enabled, but after about 2 minutes it becomes disabled again. => Any idea what is going on?

See the change log for Firmware 5.2, specifically:
Alternatively, you can downgrade to firmware 5.1.
- Limit the validity of a CS command. A remotely set control setpoint expires after just over a minute. This is a safety feature to prevent runaway heating when the controlling program loses its connection, or crashes.
Alternatively, you can downgrade to firmware 5.1.
