The problem

Hi, I just upgraded to the new suggested OS today (2024-02-26) and checked the log, and found

2024-02-26 15:33:16.691 WARNING (MainThread) [homeassistant.components.utility_meter.sensor] Source sensor sensor.watermeter_raw has no unit of measurement. Please create a bug report at https://github.com/home-assistant/core/issues?q=is%3Aopen+is%3Aissue+label%3A%22integration%3A+mqtt%22

Hey there @emontnemery, @jbouwh, mind taking a look at this issue as it has been labeled with an integration (mqtt) you are listed as a code owner for? Thanks!

This cannot be related to the OS update, only to a HA core update. Nevertheless, as the error message says "sensor.watermeter_raw has no unit of measurement" but the utility_meter requires a unit set on the source entity. you should check and fix the sensor.watermeter_raw so it contain a valid unit of measurement

It is not an issue with MQTT either.

Hi alltogether, all I can tell, that yesterday 2024-02-25 17:35 I did a reboot and did not see this error in home-assistant.log. Today I did the OS update and got this message. Do you need any other information or logfile? Btw. The data from the watermeter is still arriving, and I see no difference.

thanks Juergen

"Source sensor sensor.watermeter_raw has no unit of measurement"

does it ?

[Mariusthvdb]

you should have smthng like this:

    - unique_id: watermeter_smart_gateways_current_value
      state_topic: watermeter/reading/current_value
      name: Watermeter stand
      unit_of_measurement: L
      state_class: total_increasing
      device_class: water
      <<: *device

(nevermind the bottom 'device' yaml anchor there, its only for creating a device, and not to do with the UOM warning)
