Unable to setup MQTT
I have OTmonitor publishing to /events/central_heating/otmonitor.
When I try to setup SAT with MQTT gateway and I use otmonitor for the "top topic" I get "No matching devices fount" when selecting "Device".
HA core: 2024.1.2
HA superviser: 2023.12.0
OS: 11.3
Frontend: 20240104.0
SAT version: 3.0.1
installed through: HACS
You have to setup the MQTT integration and it has to find the device, so you can select it.
I think I misread the first message. Do you use the Wi-Fi or the Ethernet version of OTGW?
I use the otgw hardware from https://otgw.tclcode.com/. The gateway is connected via serial to a RPI that runs otmonitor (https://otgw.tclcode.com/otmonitor.html#configuration). Otmonitor is configured to use MQTT for publishing it's data. HA runs on a different computer and I installed mosquitto MQTT integration on it. In configuration.yaml I added: mqtt: sensor: - name: "cv_flame" state_topic: "events/central_heating/otmonitor/flame" value_template: "{{ value_json.value }}" - name: "cv_hotwater" state_topic: "events/central_heating/otmonitor/hotwater" value_template: "{{ value_json.value }}" - name: "cv_centralheating" state_topic: "events/central_heating/otmonitor/centralheating" value_template: "{{ value_json.value }}" etc.
So I can view Opentherm data on a dashboard.
Hope this will clarify my setup.
Unfortunately that isn't supported. This component is designed to work together with the MQTT variant of: https://github.com/rvdbreemen/OTGW-firmware.
You can try serial connection route though, although not recommended.
Maybe I can make a mqtt translation? What mqtt structure is SAT expecting?

There would be a lot of things you would need to expose, and it also needs the ability to send commands, otherwise it can't change the setpoint for example.
Or you can create a new connection type that will connect to OTGW through OTMonitor. You can have the mqtt connection as example.
