Hello @k33g

in the M5Stack world there are 3 different Groove ports (A - red, B - black and C - blue) for different types of units.

PORT                 PIN         Note:
PORT-A(Red)    G21/22  I2C
PORT-B(Black) G26/36  DAC/ADC
PORT-C(Blue)   G16/17  UART

The Groove port built into M5Stack (Gray, Fire, Basic, etc.) is port A (red).

However the watering unit needs to be connected to port B (black) for the example to work.

Note: Groove port B (black) and port C (blue) are available on the M5GO Bottom.

Thanks
Felix

@world101 said in M5Paper and API Key:

@ajb2k3 Actually, most of the time when I flash new firmware with M5Burner, it does assign a new API key to my device. Maybe that is because I always erase the flash before burning the firmware. I just tried it and it gave me a new API key.

@k33g give it a try. The Erase button is in the upper right corner of M5Burner. Then burn the latest M5Paper firmware.

I thought i was supposed to but for me, lately, it looked to always generate the same api.
