This is a change that’s being made within Home Assistant as part of the new weather entity types, which I migrated to in version 1.1.0. The old types will stop working in Home Assistant 2024.3 so I had to switch over to the new way of doing things or else this integration would stop working in about 5 months.
From my understanding the only way to do this now is to create triggered template sensors as described in this post. That will allow you to expose individual attributes (like precipitation) as their own sensors, which you can then use however you’d like.
