@RL_Dane The SQFMI Watchy (https://watchy.sqfmi.com/ and https://sqfmi.com/watchy/) is pretty cool. I have one. It is ESP32-based. The Arduino library for it isn't good, and the hardware is okay, but it has a screen, WiFi, and is programmable. I love it.
@RL_Dane It isn't in the GadgetBridge list of supported devices. Watchy is very DIY, if you want a feature then you can make it yourself, or find someone else's code, and flash the device (over USB). It works with Arduino and PlatformIO. The Discord chat group (https://discord.gg/ZXDegGV8E7) is helpful.
@RL_Dane So far there isn't a feature for connecting to your phone (that I know of) in a useful way. It has Bluetooth (BLE) and has code for fetching Weather via WiFi though!
