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
