        Ok, the issue is definitely with the extension firmware 5.6. The current version is 5.18 and for some reason, both of you received extension units with the old firmware... We do apologize for this, if it is even possible.

        The @salorob was able to flash the firmware by his own via our Windows application tool. Unfortunately, the tool is also long time waiting for the update, so the firmware version in this tool is only 5.9, instead of 5.18.

        So the official hacker's tutorial is:

        1. SSH into your controller, the user "pi", the password (if not changed) is "raspberry". If your image is Raspbian, you need to install additional packages:
        pi@raspberrypi:~ $ sudo bash
        root@raspberrypi:/home/pi# echo "deb https://files.unipi.technology/debian stretch main" > /etc/apt/sources.list.d/unipi.list
        root@raspberrypi:/home/pi# wget -O - https://files.unipi.technology/debian/unipi_pub.gpg | apt-key add
        root@raspberrypi:/home/pi# apt update
        root@raspberrypi:/home/pi# apt install -y neuron-firmware neuron-modbus-tools
        
        1. Connect the extension to the controller over RS485. If you have multiple extensions, connect only one at a time. Right now, all of them thinks they have address 15, so you need to avoid collisions.

        2. Confirm, you have a connection to extension

        root@L503-sn101:/home/pi# /opt/neuron-bin/fwserial -p /dev/extcomm/0/0 
        Boardset:     5 E-14Ro_P-11DiR485              (v1.0)
        Baseboard:    2 E-14Ro                         (v1.0)
        Firmware: v5.6
        Modbus timeout set
        
        1. Flash the firmware
        root@L503-sn101:/opt/fw# /opt/neuron-bin/fwserial -p /dev/extcomm/0/0 -PR
        Boardset:     5 E-14Ro_P-11DiR485              (v1.0)
        Baseboard:    2 E-14Ro                         (v1.0)
        Firmware: v5.6
        Modbus timeout set
        Programming page 00 ...Finished programming chunk 0, ret: 64 err: 0
        Finished programming chunk 1, ret: 64 err: 0
        Finished programming chunk 2, ret: 64 err: 0
        Finished programming chunk 3, ret: 64 err: 0
        Finished programming chunk 4, ret: 64 err: 0
        Finished programming chunk 5, ret: 64 err: 0
        Finished programming chunk 6, ret: 64 err: 0
        Finished programming chunk 7, ret: 64 err: 0
        Page written OK.
        
        Programming page 01 ...Finished programming chunk 0, ret: 64 err: 0
        ..........
        
        1. Verify the firmware. Since the flashed firmware now accepts address set by DIP switches, you need to specify the address in the parameter -u. My extension has address 3
        root@L503-sn101:/opt/fw# /opt/neuron-bin/fwserial -p /dev/extcomm/0/0 -u 3
        Boardset:     5 E-14Ro_P-11DiR485              (v1.0)
        Baseboard:    2 E-14Ro                         (v1.0)
        Firmware: v5.18
        Modbus timeout set
        
        1. Repeat the process for all of the extensions

        Let me know, how it worked. If you don't want to flash the firmware yourself, let me know and we can arrange some remote session with you.

        Thanks,
        Martin

          @martin-kudláček Thanks a lot, it works now :) I can set another address than default now!
          Firmware is now 5.9 (it was 5.6 as you said), is there any need to upgrade to 5.18?

            @bsc101 So I guess you used the Windows firmware update tool as @salorob. There are definitely a bugfixes from version 5.9 with some new functionality as well. You have the tutorial above, so you can update it, if you find out you need it.

                @martin-kudláček My fault, did not do step 1 in your decsription above since fwserial and firmware files were already present. It's 5.18 now, thank you!

                    So I tried with an official Unipian image, but still same problem. Some security issue (gpg: no valid OpenPGP data found). Please help @tomas_hora @Martin-Kudláček

                      The files has been moved into a new repostirory: https://repo.unipi.technology/debian/ The FW tool for extension can be found here https://kb.unipi.technology/files:software:tools:00-start#extension_firmware_update_tool

                        Thanks! I was able to flash the device using the FW update tool and now it says it v5.36 on it.

                        Too bad I'm not able to try it out now, as on my test Unipi I accidentally plugged in the power supply on the RS485 port and now I get

                        root@L203-sn81:/home/pi# /opt/unipi-bin/fwserial -p /dev/extcomm/0/0
                        Read version failed: Connection timed out
                        

                        Will need to get a new Neuron for this.
                        Thanks for the help! :)

                          @boy-lenssen Yeah, that's something we are working on to protect bricking the units during the FW upgrade process. If the RUN led is dead, send it to us so we can reflash the FW.
