  @martin-kudláček sorry for the late reply. My node-Red interface is only used to send/receive the intensity to a specific address or group and create scenarios. Once you have documented your documentation about dali I could check the files and try to make some changes and pull requests to the projects if needed. Thanks

  Hi @Boy-Lenssen, I have created a tutorial, how to flash the firmware via SSH: https://forum.unipi.technology/topic/693/multiple-xs50-on-a-l513-rs485/20 Let me know, if you are OK with this. We certainly can update the firmware for you via Teamviewer as promised above. Thanks, Martin

  Hi @DSurname , if I understand it correctly, you are running your application on the M103 and you want to control the inputs/outputs on the M103? In that case, you cannot (or shouldn't) use ModbusRTU, because there is no Modbus Slave (Server) running on the M103 by default. To access those inputs/outputs, you can use many of the supported interfaces described in the official documentation: https://evok.api-docs.io/1.0/jKcTKe5aRBCNjt8Az/introduction Martin

  @tomasknot Thanks. I had Unipian image with old version of EVOK. After flashing new image, everything works.

  It is possible, but it requires using our image instead of Raspbian. You should be able to use /sys/devices/platform/unipi_plc to find out more information about the system, or simply run "sudo dmesg" after boot, as the image driver performs automatic diagnostics.

  @rob It listens on 127.0.0.1 by default. The tool is written by us (you can find the source code at http://git.unipi.technology:3000/UniPi/neuron-modbus-tools, though note that not all of our software is opensourced) so I am quite confident it is necessary. It is of course not necessary if the client software is run locally via 127.0.0.1. That said, the Linux libmodbus library did contain a bug where this setting was not applied correctly and ignored instead. Somewhat humorously I believe that the bug is still there in the version used on the main Debian repository (we statically link against a newer version of the modbus library instead, which does not have this issue), and as a result quite a few IoT devices likely unintentionally listen on all IPs. (Incidentally this issue was uncovered by DavidCozens, to give proper credit)

  Hi @d00773! Unfortunately there is no simple way of updating EVOK, as changes in the installation script cannot be easily applied retroactively to old installations. However for smaller updates you can replace the files in /opt/evok with the files in the evok directory of the latest release. Otherwise you will have to use a clean new image. We are working on a more modular installation procedure, but it most likely will not be backwards compatible.

  @unix The issue should now be fixed both in Master and in the latest release. v.2.0.5f As a side note you can now query the version of your EVOK via /version/, though unfortunately it only applies from v.2.0.5f onwards.

  Hello @Klaus-Wittstock, as stated in the readme file in the Firmware which is distributed in the image gets automatically updated at first boot? Did you wait a few minutes to let it flash correctly? If yes, there was some issue with FW for the analog boards, that caused such issue,s, but that should have been taken down. Anyway from what it seems, the FW on the group2 is damaged and currently the only way to fix it is to send it back to us... Please send me an email so we can discuss it in private.

  Hi @knebb. We use a modified kernel. You can use the commands apt-mark hold raspberrypi-bootloader apt-mark hold python-tornado apt-mark hold raspberrypi-kernel to prevent it being broken (also true for the Tornado webserver). As a side note you should generally not do apt-get upgrade regularly on a non-desktop Linux system. 90%+ servers in the world do not do so to avoid precisely such issues. The same goes with any custom software. It's really only "safe" to do on a desktop with only standard packages, and even then it can sometimes break things. This is in fact the reason why Linux keeps older versions of packages in the repositories in the first place. We plan to release packages, but all the above will still apply, functionally the differences will be a) possibility to update UniPi software via apt b) not needing to use the above commands manually (they will be instead done by the packages during installation) You are of course welcome to compile the kernel yourself against any version which you wish, it's openly available in our repository.

  The configuration looks correct - are you sure that the address jumpers are set correctly? As per: https://forum.unipi.technology/topic/75/trying-to-connect-8-relay-addon-emo-r8/11

  It might be best to try again with the latest version. The EVOK version cannot be easily found since it's done via GitHub versioning, the easiest via is by checking which installation file/image has been used. Apologies I did not get back to you earlier, but do try it with the latest version.

  I'd rather send it directly, it's only in source code on git and compiling it is not trivial. You should have the link in your messages now.

  We don't have an upgrade procedure yet. We plan to move to using debian packages, which will make the problem a lot easier, but for now you should just use a clean system. Installing EVOK twice on the same SD Card installation/image might break something, depending on various factors.
