We have completed internal testing of Evok v3 and operating systems based on Debian 12 Bookworm. Don’t miss the chance to try the latest updates, join the community and let us know what you think!

Evok v3
The main changes are described on Github (currently in the [dev-bookworm branch)

General information:

• Evok v3 is based on Python 3

• The API has been reviewed - some methods have been changed and some dropped completely

• Configuration file has been completely rewritten to yaml

• Example web site aka 'Unipi Control panel' has been split into separate project evok-web

• Completely new documentation

  • Description, installation guides and simple usage examples are available on https://evok.readthedocs.io/en/latest/
  • Complete REST API documentation is released in OpenAPI format and on https://unipitechnology.stoplight.io/docs/evok/

• What to do if something doesn't work?

  • The best thing to do is to open an issue on GitHub or contact us at support or send us an email at support@unipi.technology

• Where to download / how to install?
  Follow the instructions for installing the beta version - https://evok.readthedocs.io/en/latest/installation/#beta-version

Operating systems general information (Base OS, Node-RED OS)

• Revised way of obtaining and presenting hardware information thanks to unipi-id which unified access to peripherals https://kb.unipi.technology/en:sw:02-apis:04-sysfs
• Automatic configuration of the operating system using the platform-dependent os-configurator tool thanks to unipi-id
  • Usable for configuring custom applications
  • Documentation on GitHub - https://github.com/UniPiTechnology/os-configurator
• Updated internal bus protocol for communication with I/O to achieve lower latency
  • What does it bring? Faster access to I/O in some cases (6 registers requests) by up to 100%
  • Requires firmware > 6.20
  • Currently supported only for Patron. Support for Neuron is under development.
• Firmware is automatically updated after the first start of the beta OS Deb 12 (only for FW >=6; others need to be uploaded manually)
• Completely redesigned access to I/Os of Unipi 1.1 and Unipi 1.1 lite
  • Unified access to I/Os with other controllers using Modbus TCP https://github.com/UniPiTechnology/unipi-one-modbus
• New Linux kernel 6.1 used
• 64bit operating sytem images are generated for Raspberry Pi platforms (Unipi 1.1, Unipi 1.1. Lite, Neuron)
• Networking uses systemd-networkd and systemd-resolved
• Base OS
  • Renamed OpenSource OS to Base OS
  • Evok is no longer a native part of Base OS and should be installed manually
• Node-RED OS
  • Uses the latest Node-Red 3.1.8
  • Released new nodes node-red-contrib-unipi-evok 0.0.7 supporting Evok v3
• Discontinued support for Axon controllers
  • New OS images for Axon series are no longer provided
  • Software tools will no longer be updated
• Where to download from?

Dobrý den,

na Váš dotaz byste měl najít odpověď v tomto návodu https://kb.unipi.technology/cs:sw:01-mervis:task-definition-hidden

Hi,

the links to download beta version of the Node-Red image based on Debian 12 is here https://evok.readthedocs.io/en/latest/installation/#installing-beta-os-image

Hello @Stoeffel do you have any link or examples?

Weird... @Petr-Helebrant could you please verify it really depends on the Mervis IDE 2.4.0 and its RunTime? @Martin-Kudláček please assist on this

Hello, the Mervis IDE has been released last week. Until this, the NVRAM has been overwritten with every cycle of the RunTime which depends on the complexity of the executed application...

@Petr-Helebrant vám you provider the log from the PLC(right click on the PLC)? Also can you ssh to the PLC (you need to enable ssh und the properties tab and Upload configuration) and check directly from the PLC what IP do you actually ping when you run ping db.unipi.technology ?

Hello everyone,

we suggest using SLC or pSLC cards. The differences are explained in this article https://www.unipi.technology/key_feature/what-are-the-differences-between-memory-card-types-and-why-is-it-important-to-know-them-371

Additionally, check the new upcoming Mervis IDE which features an option to configure the period of writing the nvram file (variables used at startup of Mervis RT) to the storage. If your application handles monitoring, you can set the period to 1minute and significantly reduce the amount of data written to the card.

@Poelie Check configuration of JP2-JP5 since this should be all except the motioned wiring and configuration.

@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.

Dear @Peli as far as I know nothing has been done regarding the Mevis&Zigbee topic. As mentioned previously, the easiest way is to use Modbus Zigbee gateway or some USB Zigbee dongle and implement the SW in a different application (Nodered) and tunnel the data to Mervis using Modbus or Bacnet.

@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

@noelvaes Did you reboot after the kernel modules were installed?

The development and support of the Codesys plugins for Unipi products has been discontinued by the developer. Unfortunately, there's not much we can do about it. We asked them to release the package as Open Source... More info at https://kb.unipi.technology/en:sw:03-3rd-party:codesys#codesys_on_unipitechnology_products

This is not a standard feature of ST or FBD but there is a small hack to achieve this. See the example below. It only works if the input variable is named "in" (the same works for output variable named "out") and the type is array.

FUNCTION InDemo : LINT
VAR
i : INT;
END_VAR

VAR_INPUT
    In : ARRAY[0..63] OF BOOL;
END_VAR

(*function block's body*)
result := 0;
FOR i := 0 TO 63 DO
       // nejaky kod
     IF In[i] THEN result := result + 1; END_IF;
END_FOR;

InDemo := result;
END_FUNCTION

Hello @wicked,

an alternative way to read data from the is Modbus RTU utilizing the RS485 serial line. Unfortunately, that only available as a standard feature of Neuron and Axon lines, but not in Unipi1. However you can use any USB-RS485 converter which is available on the market.

Hi @ZigZak,

did everything worked well after the call and email with our Support?

Hello @tmmke,

the baudrate and other parameters should be configured as decribed in the product information https://www.unipi.technology/unipi-neuron-s103-g-p107?categoryId=8

If you are using the latest Mervis IDE and Mervis OS 2.3.0, you do not need to worry about the setting the GPIO18, which is done automatically.

To send the SMS, you can follow similar tutorial https://kb.unipi.technology/en:sw:01-mervis:sending-sms-hidden

GPRS (internet) connectivity is not supported in Mervis and has to be done manually in the Linux as discussed here https://forum.unipi.technology/topic/463/s103-g-use-gsm-gprs-module-to-connect-to-internet/7

Note: The modem cannot send SMS and provide GPRS connectivity at the same time!

Hello @LubomirMaron,

If you decide to go with Meris, do not mix other solution - the direct switch functionality can be configured in Mervis as well. You see it's disabled because Mervis does not read the actual configuration from the device. It expects that the IDE is the only tool to configure the HW so the latest configuration should be there.

However, the previous configuration of DirectSwitch should not have any affect to Mervis. Are you able to deploy the solution to the PLC? Could you share yoru solution with us?
