Describe the issue

A warning appears in the logfile of HA after reboot about unit of measure.
Not really important as all works fine. I do not understand the complaining of HA as L/h is the UoM of the flow rate.
Warning message:
2024-12-27 16:08:10.097 WARNING (MainThread) [homeassistant.components.sensor] Entity sensor.heatpump_flowmeter_flowrate (<class 'custom_components.quatt.sensor.QuattSensor'>) is using native unit of measurement 'L/h' which is not a valid unit for the device class ('volume_flow_rate') it is using; expected one of ['ft³/min', 'L/min', 'mL/s', 'm³/h', 'gal/min']; Please update your configuration if your entity is manually configured, otherwise create a bug report at https://github.com/marcoboers/home-assistant-quatt/issues

Reproduction steps

1. In my case: Reboot HA and it is one of the first entries in the logfile

Not needed(?), this is about a warning log entry

Diagnostics dump

No response

I have the same in logging. It is the result of Home Assistant doing a metrics rework. L/h now has become m3/h.
I haven't seen an announcement yet when they stop supporting the old metrics like L/h.

[tuimz]

It is not an effect of the metric rework. L/h was never an option, see also https://github.com/home-assistant/core/pull/106077/files

The reason for this error to appear is that since the latest release the flow meter uses the proper device class.
So effectively this addmon needs to convert Litres/hour to litres/minute and use the proper unit for that sensor.
