Hello @water5 today I got my gesture unit and I can confirm that it works fine with M5Core2 but fails to work with M5AtomLite using UiFlow firmware 1.9.8. What I found however is, that the gesture unit starts to work with M5AtomLite as soon as I add another I2C unit. I also double-checked with an I2C scan: only gesture unit connected to M5AtomLite and the scan finds nothing. Gesture unit and PbHub connected to M5Atom and the scan finds both. Go figure... Thanks Felix
