EVOK shows no I/O - Neuron L513
I bought an unused Neuron L513 (Serial-Number: 1) and I want now to test the EVOK control panel. I started with a fresh Pi OS "Buster" and installed the EVOK like it shown in the documentation. But when I start the web frontend the control panel shows only the "Analog Input 1.01" - no further entries on in- or output. Them same at system.
EVOK service ist running. What did I wrong?
Can you enable debug logging in the /etc/evok.conf and check the /var/log/evok.log file after restarting the service? Even though you're on a totally different platform, this looks like a similar problem as what I ran into yesterday as well: https://forum.unipi.technology/topic/1124/unipi-1-1-raspberry-pi-4-buster-evok-node-red
here ist my evok.log with debug=on. Evertything seems fine, but it still won't work. I only see Analog Input & Output from 1.01.
I also made a snapshot from my evok.conf
And as I saw it on your post made an output from dpkg -l | egrep "raspberrypi|evok|unipi|python"
Maybe @Martin-Kudláček could help me too?
sorry for the very late reply. Have you already solved the issue? If so, can you please share the solution?
Thank you so much!
unfortunately my problem isn't solved. I think there is an programming error or a hardware malfunction. Everytime I try an http://ip-neuron/rest/all I get an error "SyntaxError: JSON.parse: unexpected character at line 1 column 5827 of the JSON data".
I use the FHEM module for Neuron and can add manually the devices. After adding a relay in FHEM an switch them. The relay is also shown in the EVOK Control Panel. Saving the current state in flash isn't working too. When I restart/reboot the Neuron all manual added inputs, outputs etc. are gone and I just see only AI 1_01 and AO 1_01 like in my first post.
I also tried to communicate via Modbus. It worked as long as I didn't restart/reboot the Neuron. Afterwards I have the same behaviour like described above.
I use the latest Neuron-OS-Image from 21.12.2021. The installing process of OS and EVOK was without any error.
For now I can't use my Neuron because it's to unsafe for loosing all devices after a reboot oder repower.
Maybe this further information may help you to give me an advice.
Thank you and a I wish you a happy new year!
In the event monitor of FHEM I can see also the following message when I make a "get all": "2022.01.02 14:17:08 3: Neuron (NeuronL513) error decoding response: malformed JSON string, neither tag, array, object, number, string or atom, at character offset 5830 (before "NaN, "circuit": "3_0...") at ./FHEM/00_Neuron.pm line 424." As I can see the error occurs on AI 3_01 or an other till AI 3_04.
