In other words, use the Play Store on a non-Graphene phone for the Blink app, and use the hotspot on my Graphene phone so that I can get an internet connection?
You are correct, it is not a great option, however it is an option.
Another person who replied above suggested the available RFID card. That would be a good option, however again, unless I am mistaken, an account with the app is going to be required to use it.
I currently have a support ticket open with Blink Charging,, who at this point in time have referred my support ticket to the dev support team. I have also sent them the [https://grapheneos.org/articles/attestation-compatibility-guide](https://), so perhaps that will help. For now, I guess I will have to wait and see what support says.
