Did you ever progress with this issue. I am trying to pair the 8Ch Encoder unit with an M5Dial and am getting no-where. Fairly sure like you its an I2C issue.
Strangely I had no problem getting it to work on a bare bones ESP32 Dev Module on the default I2C pins. https://www.az-delivery.de/en/products/esp32-developmentboard
See Code Below for that working example.
Somewhat Ironic that when trying to pair it with one of their own Boards (M5Dial) it doesn't work out of the box. UIFlow2 works fine. I just cant for the life of me get the Arduino framework example they provide to work.
