Utility Meter (hourly reset) not showing unit_of_measurement

[EddyK69]

The problem

I made an (hourly reset) Utility Meter of a sensor with unit_of_measurement 'mm' (Rain), but the new sensor doesn't show any unit_of_measurement. If I change the sensors attributes with a manually added unit_of_measurement, it drops it when the reset occures.

What version of Home Assistant Core has the issue?

2023.6.3

What was the last working version of Home Assistant Core?

Anything in the logs that might be useful for us?

The unit of sensor.regen_dit_uur (mm) cannot be converted to the unit of previously compiled statistics (None). Generation of long term statistics will be suppressed unless the unit changes back to None or a compatible unit. Go to https://my.home-assistant.io/redirect/developer_statistics to fix this

Hi,

I have more or less the same issue and perhaps even stranger. I have one source sensor for the watts, which I use in an integration to give me the kWh similar to what you have done in your description. After that I use the Utility Meter integration on 4 levels: hourly, daily, monthly and yearly cycle. The monthly and yearly give device_class: energy and unit_of_measurement: 'kWh', exactly as expected. The other 2, hourly and daily don't do that. The numeric value though is correct for all of them..

state_class: total_increasing
source: sensor.cum_kwh_heat_pump
status: collecting
last_period: 0
last_valid_state: 0.040
meter_period: monthly
cron pattern: 0 0 1 * *
last_reset: 2023-07-05T21:46:05.274063+00:00
unit_of_measurement: kWh
device_class: energy

I have multiple set-ups for other 'consumers' working flawlessly. I can't find any typo's, I have searched and searched, modified and tried but so far no results.. I have no clue. A true bug perhaps?

I have the same problem with the daily sensor, not showing unit of measurement. All others (hourly, weekly, monthly, quarterly, yearly) are fine.

I just created this sensors yesterday, because the utility meter I created some weeks/month ago, showed the wrong unit of measurement, namely Wh instead of kWh.

The underlying sensor is a homematic (measuring switch) energy counter and it's energy_counter-reading, which is usually in kWh.

Is there a way to set the unit of measurement for such helpers derived from other sensors after they have been created?

[vincenzoca69]

idem if I create it with a certain name it gives me the unit of measurement as I change the name it disappears and in any case the problem is with daily, tried today with yearly reset same problem

Same here, although it's inconsistent.

Natural Gas Daily, Natural Gas Monthly, and Water Monthly have units, but Water Daily does not.

My config:

utility_meter:
  natural_gas_daily:
    unique_id: d0740580-f30f-4b61-9ecc-4d3b30ddd18a
    source: sensor.meter_gas
    name: Natural Gas Daily
    cycle: daily

  natural_gas_monthly:
    unique_id: eccfa12d-4d46-4615-95d6-2c2f789f8f39
    source: sensor.meter_gas
    name: Natural Gas Monthly

    ## reset manually; read date is inconsistent
    # cycle: monthly

  water_daily:
    unique_id: 8289b887-cddc-4e14-98fe-6d8ac2673779
    source: sensor.meter_water
    name: Water Daily
    cycle: daily

  water_monthly:
    unique_id: 10353dfd-449f-45ab-8f47-e17f87e4e158
    source: sensor.meter_water
    name: Water Monthly

    ## reset manually; read date is inconsistent
    # cycle: monthly

Same problem here. I have 4 identical sensors for my meter readings (import low and high and export low and high). For all of them i created utility sensors. Two are working correctly and showing kWh. The other 2 dont.
