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
Stefan
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

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

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:
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
