Hello @Rusticus42

there is a solution: use a M5PbHub unit (which is an I2C unit) to read the button states of the Dual Button unit.

I created an example in the UIFlow2 Project Zone: M5AtomS3_RFID_PbHub_DualButton_Test_UIFlow2.3.7

Note: I do not have an M5AtomS3R so you probably need to adapt the example.

Thanks
Felix
