      Hello,
      I have the same problem but I use NodeRed and EVOK API.
      All the sensors connected directly to my Neuron L203 started showing a constant temperature out of nowhere, which was very dangerous. However, the sensors connected via xG18 were showing correctly.
      Since then I restart the evok with cron task every hour just to be safe. systemctl restart evok.

      Hi @ArnieX,

      Thank you for your post.
      This is a typical error when setting up communication with INEPRO/KLEFR electricity meters, and it is really necessary to be careful when setting up other devices (modbus tables).

      Best regards,
      Antonin, Unipi

      Dobrý den,

      zabýval jsem se tímto zapojením více a skutečně jsem odhalil problém s připojením čidla 1W-T-IB(2) k Unipi xG18. Jedná se však o vlastnost obvodu na desce.

      S vaším aktuálním zapojením bude nejjednodušší úpravou přepojení vodiče ze svorky +5V na svorku GND. Po přepojení již budou tyto čidla fungovat. Čidla v podlaze Vám předpokládám fungují všechny bez problémů.

      Poznámka: Aby bylo možné čidla 1W-T-IB(2) provozovat s xG18, stačí na svorky čidla připojit pouze dva vodiče (1W + GND), k tomu lze využít např. dvě prostřední svorky.

      Hello @Vesa-Kauppinen,

      this has been subject to change between Linux kernel versions - the older one

      cat /sys/devices/soc0/soc_uid

      comes from the original iMX kernel and has been removed by NXP in newer releases. In our kernel image, we additionally preserve it for backward compatibility.

      However,

      cat /sys/devices/soc0/serial_number

      is a "Linux standard" provided by recent NXP kernels that we recommend using as a unique identification.

      Hello everyone,
      we have just released updated Zulu kernel, which solves this particular problem.

      The problem has been in the memory lock, which overused the swap, even when the swap is off on all our OS images. This has been fixed in kernel 5.10.17+. The new kernel is 5.10.35.

      Whole suite of OS images is currently being generated and within an hour uploaded to the Download section

      Thank you for reporting the issue nad have a nice day,
      Martin @ Unipi

      Hi @knebb,
      you have verified, that the HW is working and returns correct value via standard tool. Checking and fixing your code is unfortunately beyond the scope of the free support.

      Thank you for understanding and have a nice day,

      Hi @Csevi,
      in short - the 1-Wire hub is passive device, which helps with the "linearization" of the star topology. You can find complete information about 1-Wire here: https://kb.unipi.technology/en:automation:02-glossary:1wire-hidden

      Hello @daminou53 ,
      we have released the Patron kernel (more precisly the "Zulu" kernel - Zulu is the codename for the SBC). Here's the repository: https://git.unipi.technology/UniPi/zulu-linux. Here are the config files: https://git.unipi.technology/UniPi/zulu-linux/-/tree/zulu_5.4.70/arch/arm64/configs

      @tomas_hora, thank you.

      I have been reading more about your products and I found out that EVOK provides websockets. I was thinking that I would write a script which would process MQTT messages from a dongle and deliver them to Mervis using websocket and the other way around. Would that work? It would replace the Node-red which you suggested.

      Thank you for your help, Martin.

      I fixed by simply removing gateway and dns-nameservers definitions from the eth1 file.

      If anyone is interested in this the solution to make this working with also the gateway check: https://www.thomas-krenn.com/en/wiki/Two_Default_Gateways_on_One_System

      Hello @Jan-Toth,

      you have not specified IDE/Language used. For example, in Mervis IDE you can use the following approach:
      Automatic restart of the 1-Wire bus

      Can you share more info about the application?

      @martin_triska said in 1-wire sensor and modbus sensor:

      in this case, you have to tie the wires manually ON THE SENSOR. According to the photo, you have to connect dark-green and light-brown wires together ON THE PCB

      Yes, that did the trick!

      Thanks for the education and superb support here Martin. Really enjoy using your products.
