strconv.ParseFloat: parsing “M2”

This means that your MQTT topic includes a value called “M2”, which clearly is not a float value. You might try setting data_type = "auto_float"

After setting the value auto, I unfortunately no longer get any values ​​in. I know that most values ​​are floats, but there are also a few strings. But I don’t know how to adjust my config afterwards

this is the output —> data_type = "auto_float"

Using --test with the mqtt_consumer is not going to work. The mqtt_consumer sits and waits for records and metrics. Test only runs for a single “collection” cycle, which the mqtt_consumer does not have.

You can use the test wait like you did, but it needs to be long enough to get records.

Additionally, you can consider using the client_trace = false with debug mode turned on to get even more logs from the mqtt_consumer.

I don’t need the data that shows an error, can I somehow deactivate it with a command?

In that case, you can drop the data with a processor like starlark or you could go back to your original config and ignore the errors.
