Domoticz

I just replaced my wired thermostat for an Intergas InComfort + Gateway and connected the OTGW from Nodo shop. After adding the OTGW hardware to Domoticz (IP port 23),it took a while before devices (7) were visible in Domoticz. However, all metrics/counters are 0 and Domoticz is not receiving from OTGW:

2023-12-16 12:13 Error: OTGW hardware (20) nothing received for more than 5 Minutes!....
2023-12-16 12:13 Error: Restarting: OTGW


From the OTGW, I can see there are metrics though:
Flame statusOff
Central Heating Status Off
Central Heating Enabled Off
Central Heating 2 Status Off
Central Heating 2 Enabled Off
Domestic Hot Water Status Off
Domestic Hot Water Enabled On
Diagnostic Indicator Off
Fault Indicator Off
Cooling Enabled Off
Cooling Status Off
Outside Temp Compensation Off
Outside Temperature 0°C
Room Temperature 20,19°C
Room Temperature Setpoint 19,5°C
Remote Room Temperature Setpoint 0°C
Control Setpoint 10°C
Relative Modulation Level 0%
Max. Rel. Modulation Level 100%
Boiler Temperature 36,38°C
Return Water Temperature 0°C
Domestic Hotwater Setpoint 50°C
Max. CH Water Setpoint 48°C
Central Heating Water Pressure 1,78bar

Any tips or references to documentation that I can use?

In the meantime, I configured MQTT for Domoticz as described here: https://github.com/rvdbreemen/OTGW-firm ... -or-others

Now I get a lot more devices and metrics. What I don't quite understand: do you choose between either OTGW hardware using 'OpenTherm Gateway with LAN interface' or the 'OTGW MqttClient' hardware but not both? Without the 'OpenTherm Gateway with LAN interface' hardware, I cannot send commands or configure the outside temperature.

Use port 25238 with the lan interface.
