      Hello @PascalS

      from your first log I think the ENV III Hat was recognized properly else the log would have ended with either of the "Couldn't find ...".

      Anyways, please find an I2C scanner for internal, Groove and Hat here.

      Thanks

        @felmue Thanks for the link.

        Strangely, they are now not showing up (not found is now in the log). That wasnt before.

          The port scan went as expect, only internals are found.

          I2C Scan - internal
          ................................................................................0x51 ......................0x68 ......................
          I2C Scan - Groove Port
          ..............................................................................................................................
          I2C Scan - Hat Port
          ..............................................................................................................................

          Does that mean a hardware error?

          Greetings Pascal

            Hello @PascalS

            hmm, have you tried to power cycle M5StickCPlus2?

            1. disconnect USB
            2. remove HAT
            3. press and hold power button until green LED lights up
            4. release power button - green LED goes dark - M5StickCPlus2 is now off
            5. re-attach HAT
            6. re-connect USB - M5StickCPlus2 powers on
            7. re-test

            Thanks
            Felix

            P.S. if that doesn't make the HAT show up in the I2C scan or make it work with the original program then I am afraid that yes, there might be a hardware issue.

              @felmue Thanks for your help :)

              Propably it is a hardware failure, I do not get any i2c signals back.

              Wil return it and run it with new hardware. I update the thread when I heard back from the seller.

              Thanks for your help!

                @felmue Unfortunately, also a newly bought M5Stick and a newly bought ENV hat didn´t change anything.

                Could it be that the hat port uses another Wire?

                  Hello @PascalS

                  hmm, that is really strange. Do you have any other hat to try if the hat port works for you in general?

                  ENV III hat is supported in UIFlow2. Maybe try with UIFlow2? Just to see if it works that way.

                  Thanks

                    @felmue You were right, in UIFlow 2 it worked perfectly fine. However, I need them to work in Arduino, so that it fits with our current framework.

                    Do you know were the difference between UIFlow 2 and Arduino is?

                      Hello @PascalS

                      at least we know now that the hardware is ok.

                      Apart from that I am stumped. Sorry.

                      Thanks

                        @felmue Finally I got the solution using separate Wires and PlattformIO to manage my libraries :)

                        With the following ini file (PlattformIO config file)

                        [env:miniscale]
                        platform = espressif32@6.1.0
                        board = m5stick-c
                        framework = arduino
                        lib_ldf_mode = deep
                        monitor_speed = 115200
                        build_flags = 
                        	-DCORE_DEBUG_LEVEL=0
                        	-Wl,--allow-multiple-definition
                        lib_deps = 
                        	https://github.com/m5stack/M5StickCPlus2.git
                        	m5stack/M5Unit-ENV@^1.0.1
                        

                        Not knowing why, but I need the "-Wl" to run at all and the "--allow-multiple-definition" flag for the hat to work in conjunction with sensors mounted to the groove port.
                        It worked, however, I need to change the I2C begin call from "Wire0" (just called Wire) to the secondary I2C channel Wire1

                        Before:

                        while (!qmp.begin(&Wire, QMP6988_SLAVE_ADDRESS_L, 0, 26, 400000U)) {
                             Serial.println("QMP6988 not found");
                         }
                        

                        After:

                        while (!qmp.begin(&Wire1, QMP6988_SLAVE_ADDRESS_L, 0, 26, 400000U)) {
                             Serial.println("QMP6988 not found");
                         }
                        

                        Maybe this helps someone in the future :)

                          @PascalS Now I see the problem.
                          Wire is hard defined and set to internal.

                          You need to use Wire1 to access the external devices.
                          I vaguely remember reading about this issue before but as I don't have arduino I had forgotten about it.
                          Thanks for the reminder.
