  Hello @valtert, the description on the page is misleading. The real situation is this: Analog output on Group 1 is capable of outputing 0-10V, 0-20mA and measuring resistance up to 100kOhm Analog outputs on Group 2 and 3 and on the extensions are only capable of outputing 0-10V Same goes for Neuron and Axon product line. If you need second AO in current mode for your project, you have two options: add a second PLC as a "dumb" extension and communicate with the master PLC via ModbusRTU, ModbusTCP or SSCP purchase a 3rd party ModbusRTU IO module, such as this: https://www.advantech.com/products/gf-5vtd/adam-4024/mod_5e18f39b-38ef-4033-98f9-1ede917139ee I am sorry for the incovenience, we will fix the product description shortly. Best regards, Martin

  @knebb said in Need Some sort of Jumpstart: it writes the state as 0 or 1 into each of the uint8_t . Or, using semantic constants, as FALSE and TRUE. Directly using bits would be really slow and error prone (and I nightmare for language bindings).

  Ok, I'll do it on the board then. I'll take my chances communicating directly with the modbus tcp server instead of using Evok's layer. Cheers, Ronan

  Hi @martijn-hemeryck, those are great news! I'm glad we were able to put it together, together:) I'm looking forward for your results. Martin

  I took up the sysfs-based approach in my own (golang-based) project: https://github.com/mhemeryck/unipitt Basically, it does active polling on a series of files, representing the different inputs and pushes out an MQTT-event in case there's a change.

  Hi @anders-kjellström, it works, you can check in the default installation of the Evok: Do you have some example where the aliases don't work? Best regards, Martin

  Yes, it is clear now. You have to implement this kind of functionality by yourself as Evok does not offer it.

  @juntiedt said in MQTT to unipi Control Panel: As the flow is to big to upload I am just sendig a picture. Let me know if you want to get the flow directly. Hi @juntiedt, it looks like a very great job! Could you consider hosting the file and provide a public link? You might for instance use a Dropbox / pCloud public link, or a GitHub gist. If anyone has ideas for improvements please let me know. I think it might be possible to parametrize the flows with variables, in order to avoid repetition. At least, it seems it was done this way by @Jan-Teunis here: https://forum.unipi.technology/topic/735/node-red-flow-evok-to-mqtt-to-evok

  @pavelf Hello, it seems to something around the web-socket (used e.g. for relay state readout) connection is going wrong. The connection should be established just once, not several times per second. Can you double-check JavaScript settings in your web browser (must be allowed) and/or try an another one ?

  @roberts_lando Evok uses the Modbus TCP interface to interact with the IOs, disabling it will cause that evok wont work. You can disable it by calling "systemctl stop unipitcp" and "systemctl disable unipitcp".
