I tried several power supplies without luck (24v, 2.5A). The OTGW unit is used standalone, so without thermostat.
The TCP module is communicating fine all the way. A parallel ping shows no communication problem or outages. When I connect the reset jumper on the board, the OTGW starts sending messages again. This happens in the same telnet session.
So my conclusion is that the problem is in the OTGW module. When no hot water is used, the serial messages are ok for hours (tries a whole night).
Any ideas what the problem could be and/or how can I debug this?
