Zelp

Amazfit pairing keys, GPS packs, firmware, and watch apps for Gadgetbridge
Zelp is an Android helper for Amazfit/Zepp watches.

Sign in with your Amazfit email to:

* fetch Bluetooth pairing keys to use with Gadgetbridge
* download GPS assistance packs and optionally build gps_uihh.bin
* browse the Amazfit apps and watchfaces catalogs, download packages, and show install QR codes for Zepp developer mode

Firmware history and downloads work without an account. Xiaomi Mi Fitness login is not included.

Zelp is free software under the GNU GPL version 3 or later. It is not affiliated with, endorsed by, or connected to Zepp, Amazfit, Huami, or their parent companies. Those names are trademarks of their respective owners.

Network services: GPS, firmware, store, and account features talk to Amazfit/Zepp cloud APIs. Optionally, Zelp can scrape the Google Play listing for the current Zepp Android version. There is no self-hosted substitute for those servers.

Credentials are stored on the device and sent only to Amazfit/Zepp when you sign in. Zelp does not include advertising or Google Play Services. Firmware, apps, and watchfaces download only after you choose to download them.
