    @domi Are you using the "4Relay module" or the "4Relay unit" or the "2Relay module" ? If you still get an error, try to make a simple Uiflow programm scanning the i2c bus with the 4Relay connected: [image: 1675006854907-cfe4a152-de11-4d5b-8158-f44191defe28-image.png] You should get the number [38, 117] displayed as Label0, 38 is the decimal for 0x26. If you get 37 you have another firmware than I have (I2C address 0x25). If you only get [117] your 4Relay module is not connected to the M5Stack core. 117 (0x75) is the I2C address of the battery management chip.

    I’ve built a great extensible architecture with M5 and basically any sensor. It was mentioned in my reply https://community.m5stack.com/post/29410 It’s one thing to capture some data, it’s another to do the same in a scalable collective user base. That requires a distributed collection and messaging environment. Sensing and Controlling are two major branches of that challenge. So I think this community challenge needs to think bigger than a few M5 devices. 😄

    @dr_froggy_rd indeed , as well as just as a simple live display that's built in that a usb endoscope or usb webcam can plug into without having to use a phone depending. Or adding an external display
