Missing something

I haven't done much with MQTT, though I've had a broker on my network for a while.

I have a script publishing readings from my gas meter to topic=readings/25170699/meter_reading with a raw integer value. (I could change any of this if it helps).

I set up a MQTT Connector device pointing to the broker, subscribed it to readings/#, and created a trigger event on the topic component match. I created a MQTT Shim device ("MQTT Value Sensor Device") with the intent of capturing the incoming value.

However, whenever a message comes in, I get something like this:

Code: Select all

   Trigger                         receive gas
   MQTT Shims Debug                message_handler: MQTT message ##gas## from Docker MQTT
   MQTT Shims Debug                gas meter: processMessages: '##gas##' readings/99978223/meter_reading -> 2494
   MQTT Shims Debug                gas meter: Raw payload = 2494
   MQTT Shims Debug                gas meter: states_key=
   MQTT Shims Debug                gas meter: update adjustmentFunction: ''
   MQTT Shims Debug                gas meter: Updating state to 2494.0
   Error                           device "gas meter" state key sensorValue not defined (ignoring update request)
   Error                           device "gas meter" state key sensorValue not defined (ignoring update request)


What am I missing? What should be creating the actual value here?

Post a screenshot of the Shim config.

Attached.

Very strange. That all looks correct. Please use the context (right click) menu command to write the device details to the log and then post it here.

Oh and confirm what plug-in version you’re running.

Did you create this device as is, or did you start with a different device type then change it?

Try creating a new device and make sure you select the value sensor from the start. Use the same config data as the one you have now.

I probably did create it first as "generic device", just because I wasn't quite sure what fit, and then changed it to "sensor device".

Deleted and recreated as a sensor device, and indeed, I now see no error and the value seems associated with the device.

(While I've got you here, having CCF/HCF in the units would be nice - I believe cubic feet of gas is what is being measured here, so CCF and two decimal places would do the job).

Create a GitHub issue for the plugin for this.
