      @Peli yes, I have heard that the Conbee, zzh and Slaesh's are quite OK, but have not tried it on my own. Yes, the Node-red can run on the same device as Mervis, you'll just need to find your own way how to install and run it.

      @PhilesG The steps (if done correctly) only resize the partition so no data is lost. BTW is something goes wrong it could. I know @Martin-Kudláček also proposed me to create a script to automatically fix the partition problem, I think that would be the safer way

      Zdravím @Whitegg, píšete, že se PLC nepřipojí. Znamená to, že jej nevidíte na routeru, nebo že jej IDE nenadetekuje S pozdravem, Martin Kudláček

      Replying to my own question here: Later in the day, after some back of forth switching of the relays I was able to get 3 of the 4 relays functioning again (the other one seems lost). My guess is that it's probably not ideal to use the simple built-in relays to drive the motors directly, so my current thinking is to have a look at a set of external relays to drive the motors.

      Hello @Achilleas-Kotsis, the issue is not with the unipi-kernel-module, but with the unipi-firmware 5.52. We have removed it from our repository and advise to downgrade to 5.50 (and flash it to the HW via /opt/unipi/tools/fwspi). We are working on the fix. Thank you again for reporting this issue and have a nice day, Martin

      Hi @RaspBeginner, the relays are connected via I2C expander MCP23008. You can communicate directly with the chip by using e.g. this tutorial: https://learn.adafruit.com/using-mcp23008-mcp23017-with-circuitpython/python-circuitpython Or, which is more preffered way, to use our API called Evok: https://github.com/UniPiTechnology/evok. With this API, you will get a uniform access to all IOs across all our products. Best regards, Martin

      @PhilesG Would you please try to update the our kernel modules to the latest version? You can do this by apt update && apt install unipi-kernel-modules or by rewriting the whole OS by a new one from https://kb.unipi.technology/en:files:software:os-images:00-start#axon_generation_os using this guide https://kb.unipi.technology/en:sw:01-mervis:running-on-axon-hidden#flashing_the_os

      Hello Martin Triska, I clearly understand that a Wifi connection in a metal enclosure, close to an LTE modem is not great and that it could affect performances. Even if here, I am not using LTE and I disabled the module to be sure about that. The problem is clearly not a performance issue. Even if the connection was unstable or lost, the on board Wifi adapter is not supposed to fail like that. This is clearly an hardware bug/fault, independent of Wifi performance. The message log "brcmf_sdio_firmware_callback: dongle is not responding" is quite clear about that. Also, where do you explain in your catalog that this Wifi adapter is designed for occasional service or initial setup ? We were clearly not aware of that before buying them. Regarding the quantity of Neurons/Axons we are using, I was excepting a better support than your answer. Sorry, I had to say it. Regards. Olivier.

      @Joerg said in Update failed for unipi-kernel-modules-dkms 1.60: nipi-kernel-modules Hi @Martin-Kudláček , thank you for the quick answer - but after the "apt purge unipi-kernel-modules-dkms" the system did not want to boot anymore, so I decided to do a fresh install as described in README.apt. Best regards Jörg

      :D Oh yeah. I missed that part 🙈: you need to upload the module's configuration "Configure Unipi Module". See more about it here: https://kb.unipi.technology/en:sw:01-mervis:unipi-configure-module-hidden Thanks for your help! :-)

      Hi @CKB, the Unipi Extensions are generic ModbusRTU slaves. Since they communicate over RS485 and Unipi 1.1 doesn't have any, you need to use USB/RS485 converter. Best regards, Martin
