I have a Tank 140 with connected 4-20mA water level sensor. I'm receiving data for the sensor but I'm struggling to find the readings in the MQTT server. Anyone have any pointers?
In fact, in more general terms, is there any documentation on how the MQTT server is structured?
Have you tried dbus-spy?
I haven't, but I'm guessing this won't address the need for tank sensor measurements to make their way to the MQTT server. I'm hoping I'm just looking in the wrong place.
If mqtt is enabled, tank140 values will be present and available. Dbus-spy will show you where to find the values you are looking for in the dbus structure. Then you will know what to call with mqtt.
Indeed you were correct. It took a bit of hunting with the MQTT explorer, but I found them eventually.
Closing this out, make sure to include the tank/# topic if using the [targeted keep-alive method](https://github.com/victronenergy/dbus-mqtt#using-the-keepalive-method).
