IF YOU ARE NOT REPORTING A REPRODUCIBLE BUG, PLEASE USE DISCUSSIONS
Describe the bug
I am getting hundred of times the below error message creating thousand of error lines in the HA log.

ValueError: Sensor sensor.itresc20_forecast_summary_0d has device class 'None', state class 'None' unit '' and suggested precision 'None' thus indicating it has a numeric value; however, it has the non-numeric value:

To Reproduce
Steps to reproduce the behavior: If you configere the integration using my station "itresc20" you should get the same error.

Expected behavior
Same as for all other forecast summary sensors, none of them producde any error but the one "sensor.itresc20_forecast_summary_0d".

I have the same issue. So far not finding any workarounds other than disabling that entity.

It seems like this was previously reported in #211, but closed as not reproducible.

Maybe a clue, maybe not.

I only get errors for sensor.knywesth29_forecast_summary_0d

I have these enabled:

• sensor.knywesth29_forecast_summary_0d
• sensor.knywesth29_forecast_summary_1n
• sensor.knywesth29_forecast_summary_2d

The difference between them looking at .storage/core.entity_registry is that:

• 0d - the one that triggers the ValueError has "unit_of_measurement":""
• 1n and 2d, which don't trigger an error, both have "unit_of_measurement":null

Not sure what station our friend @cytech used in trying to reproduce the issue, I offer mine to him for testing, it is ITRESC20

[cytech]

this is an artifact from v2.0.0 corrected in v2.0.2..
it only hits this forecast sensor because of wunderground api returning null after 3:00 pm.
options you can try:
1.)
(not positive this will take..)
shut down home assistant.
manually edit the .storage/core.entity_registry as mentioned by @rct above.
change the line containing "sensor.<STATION_ID>_forecast_summary_0d" unit_of_measurement value from "" to null.
restart home assistant.
or
2.)
in homeassistant go to devices, wundergroundpws, configure, and turn off "Create Forecast Sensors"
show wundergroundpws entities, search for "sensor.<STATION_ID>_forecast_summary_0d"
enter selection mode and select that sensor and remove it.
go back to devices, wundergroundpws, configure, and turn on "Create Forecast Sensors"
go back to wundergroundpws entities, search for "sensor.<STATION_ID>_forecast_summary_0d" and enable it and reenable any others that you had enabled and became disabled...
or
3.)
completely remove the wundergroundpws integration as described here https://github.com/cytech/Home-Assistant-wundergroundpws?tab=readme-ov-file#upgrade
particularly the part about removing all wundergroundpws entities.
reinstall the v2.0.6 integration.

if you are using HACS you are on your own....

Hey,

I made the actions 1 and 3 as per the previuous post, the issue was fixed for a few days but, unfortunately it came back again and have the HA log plenty oof the same error.

I looked to the entity_registry and the "null" I added was undo. Maybe due to some HA or OS update.

Thanks

[cytech]

try v2.0.8

[kzmbj0]

Thanks for your excellent work on this.

I've just done a new installation (hadn't used any previous versions) and am running v2.0.9
I found the exact same issue. I only tried option 1 (about to try option 2). It appears that if initially working, when the sensor updates after 3pm, it rewrites the entry including the name change to "expired" and changes the unit back from null to "" - but doesn't fix it when the new unexpired version comes out.

Hopefully option 2 will work better. :)

[kzmbj0]

Or maybe not - it might be okay. I'll check again tomorrow.
