So I want te find the most feature rich smartwatch that doesn't send data to the manufacure. I have tried the Pinetime watch, but it died after 6 months.
Infinitytime (OS) was not realy that feature rish, so I want to secrufise an Open Source watch OS. But I still want to connect it with Open Source software, like gadged bridge.
What is my best option under €200? Maybe the Xioami Mi band 7 (€50) that is supported by gadgedbrigde?
You can just use gadgetbridge after the initial pairing and key generation. You need to install the xiaomi app once in some burner phone with empty contacts, or maybe you can pair it without giving it access to contacts first. Once you have the key (described in the gadgetbridge guide) you can just dump the official app and use GB without using any xiaomi data/servers.
