Hello Cleve

Thanks for reply.

sudo apt-get -o Dpkg::Options::="--force-confmiss" install --reinstall evok-unipi-data

Did what it was supposed to do.
Thank a lot for your help.

Problem:
EVOK 3.0.6 installed on UniPiOS 12.20251103.1
/etc/evok/hw_definitions/ is empty (except Iris modules)
Missing: 00.yaml, 08.yaml, xG18.yaml, xS11.yaml, xS51.yaml
evok-unipi-data shows status [residual-config]
Hardware: Neuron M203 with extensions xG18, xS11, xS51

What I tried:

apt install evok-unipi-data-full → only installs Iris modules (IM203, IM204, etc.)
apt install evok-unipi-data → after purge/reinstall still empty

Error in EVOK logs:
ERROR:evok:'readboards: Unsupported device model 00! (check HW definitions)'
ERROR:evok:'readboards: Unsupported device model 08! (check HW definitions)'
ERROR:evok:'readboards: Unsupported device model xG18! (check HW definitions)'
ERROR:evok:'readboards: Unsupported device model xS11! (check HW definitions)'
ERROR:evok:'readboards: Unsupported device model xS51! (check HW definitions)'

Are the same like in Evok 2.5. Can i copy them to Evok 3

Kind regards
Stefan

I updated Evok today to the aktual version. After that I have the problem that the values of my xG18 dosen't get updated in evok (and fhem) in realtime. I get the correct values with <ip> /json/all or when i reload the webpage. All other values over UART get updated in time.
I dosn't find any changes in evok.conf. But i tried with the newest from github with the same issue.

Hardware M203 S/N722 with 1pc. xG18, xS11, xS51

Kind regards

Hello Pavel

I have a similar problem. I now made e workaround with a shell script that restart the 1-wire bus after a fixed time. It's not nice but it works for me.

#!/bin/sh

mbpoll -m tcp -a 0 127.0.0.1 -t 0 -0 -r 1001 1 && mbpoll -m tcp -a 0 127.0.0.1 $

while sleep 120; do
echo start mpoll 'date' 
mbpoll -m tcp -a 0 127.0.0.1 -t 0 -0 -r 1001 1 && mbpoll -m tcp -a 0 127.0.0.1 $
done

Happy newyear
Stefan

Hello Thomas

Exemple with L503, xS51 and xG18. I also have some
DS18B20 on the 1Wire Bus.
Install Steps:

• Check if everything is configured and works correct in evok
• Check output of <IP_of_Neuron>/rest/all in your Browser
• Install FHEM from the repository (https://fhem.de/#Installation)
• Connect FHEM with your Neuron by typing: define <Name> Neuron <IP>:80
• set attributes like in the picture (see on the bottom) below

After that all inputs and outputs get recogniced automatically.
You will get a room named NeuronPin with all devices.

Example (with some changed names):

Example of a analog input with a PT1000 Sensor for Temp. mesurment:

Example of a analog input with a Honywell PX3 pressure sensor:

I am developing a control system with FHEM for my distillery with a heat recoupling for the building heating of the residential house. When I'm finished, I'll be glad to present the project to you.

Fhem should now work properly with all Unipi versions (tested with L503 and M203) and the extensions xS11, xS51 and xG18.
All inputs and outputs are correctly recognised and automatically created. The analogue inputs can be configured for resistance, voltage and current. The range can be set.
Many thanks to Klaus from the FHEM forum for adapting the module.

As promised, here is the feedback.
The problem has definitely been solved.
Many thanks for the help

Kind regards
Stefan

Hello Martin

I hope I have solved the problem now. My Modbus and Json/Rest have been running error-free for 24 hours.
I have done the following:

• Update EVOK to 2.4.10
• Deactivated the Modbus device in FHEM
• The Modbus is now only addressed via the Neuron Device in FHEM.

The access to the Modbus is realised with Fhem on the one hand via the Device Neuron and on the other hand via the Device Modbus. If both are installed, there will probably be conflicts which cause EVOK to crash. In any case, it was possible to get the system running again for a while by restarting EVOK.

After deactivating the Modbus device in Fhem, I no longer had any error messages in EVOK. However, after 2 hours, the Modbus hung up again. Then I updated EVOK to 2.4.10 and rebooted everything. Since then, the system has been running error-free for 24 hours.
I will get back a response to you in a week again.

Kind regards Stefan

Hello Martin
I checked again the evok.conf
I have exactly the same settings as you.
Here the output:

Hello Martin

I updated to 2.4.8. I can't see any difference. The problem is the same.

<IP>/json/all:

Also Modbus stops working after 1-5min. (Rx Tx stop blinking)

<IP>/rest/all works properly.

Greetings Stefan

Hello Martin
I have some more information for you.
I have now connected another xG18 to my M203. I can reproduce the problem there exactly the same as with the L503 in the post above. Possibly the problem is with all Neurons versions the same.
My xG18 are V1.0

I also have the feeling that the Evok frontend is updated much more slowly with connected xG18 and sometimes hangs. However, the inputs and outputs work perfectly.

I have also updated the NGINX server from the bulleye repository to version 1.18 because I had read a report in the forum with similar log entries as errors, which are patched from V.1.17 onwards. Unfortunately, this was not the solution.

Kind regards
Stefan

Hello Martin

Here's what I did:

• Downloaded your image and copied it to a new SD card.

• Set network parameters.

• Logged in via ssh and executed the following:
  sudo apt-get update && sudo apt-get upgrade
  sudo apt-get install evok

check if evok frontend is running --> okay
check if <IP>/json/all is running --> okay

• Configure xG18 in evok.conf (version above)

• restart evok

check if evok frontend is running --> okay
check if <IP>/json/all is running --> Server Error 500

If its easier I can open a Open VPN vor you to the Neuron for debugging.
I have been trying to solve the problem for more than a year now, and I bought the 4 xG18s specifically to avoid the problems with the owfs. I would be happy if we could solve the problem. By the way, I've informed and work together with klaus from fhem forum that the xG18 extensions are correctly recognised in FHEM. That's done now.

Thanks Stefan

Hello Martin
Thanks for your reply.
And <IP_Neuron>/josn/all shows correct values? Or Server Error 500?
In the Webfrontend of evok I have also correct values.

Stefan

I was able to narrow down the problem further and I think the following error messages in the nginx.log are triggered when the server error 500 occurs:

xy@sps:/var/log/nginx $ cat error.log
2021/07/01 23:05:44 [alert] 1321#1321: *1 open socket #12 left in connection 2

2021/07/01 23:05:44 [alert] 1321#1321: aborting

As soon as I comment out the xG18 in the evok.conf, the error messages are gone and the server runs perfectly.

Hello Martin
Can we please look at my issue with the Server Error 500 again.
When restart evok by "sudo service evok restart" the rest API works properly.
After app. 7s it hangs with Server error 500 as discribed above.
In the meantime I am on evok 2.4.6.
Here are the log Files:

By the way, can I configure the value reading speed (and refresh time in evok) of the 1Wire Sensors connected to the xG18 devices?

Thank you
Stefan

Hello Martin
Do you need further information? I have a second installation with a new M203. If it helps I can try to repeat the issue there again.

Kind regards Stefan

Hello Martin

Thanks for reply. I made following steps after a sudo apt-get update and upgrade to find the problem:

sudo apt-get remove --purge evok && sudo apt-get install evok

... after that, the json Server runs well, but after uncomment the three Mandatory lines for my xG18 Extension and after a "sudo service evok restart"
the Server Quit with Error 500. I can reproduce this every time.

After installation of a xG18 extention I get a Server Error 500 for the Rest Json.
With a fresh install of EVOK everithing runs fine. Then I installed a xG18 module and made the configuration in the /etc/evok.conf as follow:

[EXTENSION_xG18_1]
global_id = 2                                  ; Mandatory, REQUIRED TO BE UNIQUE

;allow_register_access = True                   ; Optional, False default, is mandatory with third-party devices

;scan_frequency = 10                            ; Optional, 10 default, scanning frequency in [Hz]
;scan_enabled = True                            ; Optional, True default

After that the Extension appear in the EVOK Webfrontend. But when I made a
http://myunipi/json/all
I get a:

Do you have any Idea why? When I uncomment the xG18 section the Server Error disapeer.

So. Now I solved the problem:
After a

sudo apt-get remove --purge evok && sudo apt-get update && sudo apt-get upgrade && sudo apt-get install evok

and with this new configuration in the evok.conf I got it:

Hello Martin

I'm a little further along.
The extension is now recognized in the EVOK frontend.

But I don't have any Inputs on EVOK in the section:

Also the tx/rx led's do not blink.
I tried with several settings, but nothing works already until now.
