I’ve fixed/added some capability icons for the Air and Sky and added the Rain Day capability so you can see the accumulated amount of Rain for the day.
I’ve sent a Pull Request and PM to @Will_o_Wisp but have not seen a reaction yet
If you want to try this version yourself you have to install it via the CLI, source can be found here: https://github.com/daneedk/com.weatherflow.smartweatherstation
Do remember you will have to re-add your Sky to add the Rain Day capability.
Edit:
The Pull Request has been merged, awaiting approval by Athom so it will be available in the app store soon.
Please remember to re-add you Sky after installing this new version!
