What a surprise:
Of course I had to immediately try it, and bingo:
According to Gadgetbridge, it’s only very basic and initial support at the moment, it only shows the battery status so far. But every journey starts with first steps like someone said, and I’m very grateful for every Google app which I *don’t* need anymore (on Google’s phones you don’t need an app for those Pixel Buds, except when you’re running GrapheneOS like me)… so thank you and bravo to the Gadgetbridge team! You rock!
And like always, thanks for reading.
