  Hi everyone, this issue is new to us, although we have experienced some performance issues with our kernel module - it might be related to what you are experiencing. I have contacted both of you over email with more details. Thank you and have a nice day, Martin

  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, Martin

  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 Best regards, Martin

  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 Best regards, Martin

  @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.

  You are absolutely correct sir! Thanks a lot for your help - now it works like a charm. I've used Neuron's RS485 for communication with xS11 and separate USB dongle with CH340C chip (a bargain really, $2.7 from CZ shop) for communication with PRO1 energy meter through the same Node-RED setup getting data from /dev/ttyUSB0. It's a pity that I cannot edit my previous post ^^ - feel free to edit it with a big warning that you cannot combine multiple processes on one serial (which is absolutely logical, but for us: HW newbies not obvious).

  thanks for your information. I have connected a 4 wire cable very close to the three wire sensor and connected the data line to 2 wires in order to use the hub. At the moment it works.

  Hello @juntiedt, this sensor comes in the 3 wire connection + shielding. You can connect it to the 1-Wire hub, ideally as a last sensor. Please consult the 1-Wire hub pinout https://kb.unipi.technology/en:automation:02-glossary:1wire-hidden

  Hi @dalibor, no, the DIs don't have this capability. Mainly because it would require to have DIVCC terminal, to ensure galvanic isolation.

  @wavoigt We have tested HMI terminals from weintek like this one https://www.unipi.technology/weintek-mt8051ip-p198?categoryId=29 via Modbus RTU (RS485). Works well but the SW setup is a bit complicated. Mervis has recently gained BACnet server support so you can connect higher verions of Weintek displays which support BACnet with Neuron or Axon via BACnet/IP Alternatively Mervis has a web based HMI so you can also use this with any web browser while on the same IP network.
