I'd like to use the device API to update the icon on my clock face.
I have the icons in the library, but
requires a base64 encoding of the image.
What is the best way to get the base64?
BTW: Updating just the icon at the clock face using icon ID is currently possible via IFTTT triggers, but they become way too expensive for such a simple thing.
So I am wondering how IFTTT can do it, but it's not possible via API.
