Current upstream QMK now includes support for Sagittarius’s four multiplexed rotary encoders. I also have an encoder-enabled VIA build and matching JSON for remapping their rotation in VIA.
Download the attached .bin and .json, then:
1. Put your board into DFU mode and flash the .bin with QMK Toolbox.
2. Open VIA in Chrome or Edge. ( https://usevia.app/ )
3. Enable Settings → Show Design tab, then load the .json in Design with Use V2 definitions off.
4. Connect your board and remap the encoder rotation and presses under Configure.
Codex helped me set it up but I flashed it to my Sag. and everything is working perfectly. =]
