Hi, My boiler does not support a lot of OT messages. But luckily the CH=1, CS '(Central Heating Setpoint) and MM (Max relative Modulation) is supported. So I could start my heating system. The HS (Heating Setpoint) is not supported, but it seems that CS overrides the HS. Now I come to the point what...

Hi, I just installed 5.1 and it seems that this problem (crashing OTGW when burner starts) is back in town. I did not go deep to check if the problem is exactly the same, but it seems so.

Do you know if the patch of 4.2.6 is also in 5.1 (or not)?

Good News! The fix helps (as you expected). I see the Error 03 and after that some R messages only. During the first few seconds the message interval is not regular. Overall it seems to be fixed! Many, many, many thanks! Are you going to 'officially' release this version? R10010A00 BD0010A00 Error 0...

Please see the attached files for the data. I tried 5 rounds, but not every round I could complete all memory addresses. 5C shows a lot of different values, I tested a number of times 1-3 times a second (as fast as a person could do ctrl+v + enter). All other addresses are tested multiple times in o...

I have dumped all the values in four rounds. Each value is dumped multiple times in the 'freeze' period. But during a freeze period the value is the same. And only address 57 shows different values over the tries. 7E -> 30,30,30,30 1F -> 41,41,41,41 5E -> 10,10,10,10 (when running ok, switches betwe...

Please check otmonitor log. As we can see, there is a flame detected and communicated. The topic title is not correct. OTGW stops when the burner shuts off. Everything is ok as long as the hot water is used (service code 6 is shown on the boiler, means DHW active). When hot water is stopped, the ser...

Disabling the LED A does not help. I don't see LED B flashing when OTGW is freezed. LED B stops flashing (visually) at the same time the serial output stops. I also changed all LED's to B ('Boiler communication') and in another try to X ('Transmitting an Opentherm message to the thermostat or boiler...

Hmmm, I made a mistake. My multimeter was on AC while measuring voltage. Now the DC voltages: Disconnected: 19.5V, steady before, while and after hot water tap. My multimeter doesn't measure any spikes or drops. Connected: 6-7V Connected and after hot water tap: 17-17.5V Today I saw several times - ...

Thank you for the reply. I do not have an Opentherm thermostat. I looked better at the timings, it is a little bit different. When I start using hot water, the OTGW reports ok. But then when I stop using water, the boiler has a 3 in the service display. As soon as the 3 disappears, OTGW stops. After...

I have a OTGW module from Nodosho with a USR-TCP232-T2. I noticed that the module stops sending serial messages when my central heating device starts the burner for hot water. The heating device is an Intergas HR 28/24. I read the serial messages via a telnet session on the TCP module. Typical outpu...
