Return Ambient PWS brightness sensor unit and remove CONF_MONITORED_CONDITIONS #25284

Breaking Change:

The unique_id for Ambient sensors uses a new formula, meaning that even though they have the same friendly names, new sensors will be created. The integration will automatically perform this migration under the hood, but if you've altered the entity IDs of any Ambient PWS entities, you'll need do the same to the new entities upon creation.

Additionally, the monitored_keys configuration option is no longer supported in configuration.yaml. The integration will now create sensors for all conditions supported by the particular device.


Following up on #24690, some Reddit users mentioned they preferred the old unit for the Ambient brightness sensor (Wm^2) instead of the new unit (lx). This PR gives users both: anytime a Wm^2 brightness sensor is created, a lx variant is created, as well.

This work also revealed an erroneous pattern in the unique_id property of Ambient sensors: they relied on the sensor name. Since the name can change, this PR also corrects unique_id to use the sensor type. This is a breaking change, as it will produce different entities than what users had before.

Lastly, based on feedback, this PR removes the monitored_conditions configuration key (per ADR-0003).
