Thanks for pointing out Gadgetbridge. While informing myself before deciding to cancel my order of the Pebble Time I already found it. However, afaik the Pebble Time is not supported by Gadgetbridge and I didn't want to buy a product I maybe can't use.

Thank you for sharing this! I had no idea it existed before, but this sounds like exactly what I've been looking for.

I want to find out if it needs to make the same requests to zalew.net.pl as the official Android app in order to configure my Pebble!
