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.

Hello @martin_triska,

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!

Kind regards
Norman

Hello @marioverhaeg,

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"

Output dpkg

Maybe @Martin-Kudláček could help me too?

Kind regards

Hello,

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?

Thanks

Hello @tomas_hora,
today I got a new RS485 USB adapter to test if the adapter is crashed. And on the first look it seems so. I tested to conncet to the xS10 via the fw-tool an it shows the following

BUT this works only once a time. After a first test I get the same results of timeouts again with the new adapter.

So I guess that there must be something in the communication between xS10 and the adapter that crashes the adapter: Could I messure the voltage or something similar to see if there is a too high peak? What would be a normal range of voltage on the RS485 bus? Or any othe ideas?

Thanks Negropo

Hello @tomas_hora,

in the past I already maked the fw update. When I now connect the xS10 to PC I get the following:

Hello,

since two days I have strange problems in communication with my xS10 over RS485 Modbus RTU. I connected the xS10 via Modbus (over the Digitus Adapter) to an USB of a Pi3 with FHEM. Everything worked fine (reading the DI's an changing the RO's). But now I have timeouts on Modbus communication all time long. In FHEM Logfile the following message occur:

2018.02.06 09:54:59 3: NeuronModbus: timeout waiting for fc 1 from id 15, Request was 0f01000000083ce2 (c0 / RO1, len 8)

Yesterday I could get it away with playing on the DIP for RS485-END. But today this trick wont work anymore.
Has anybody an idea? I don't know if the Digitus not wirking correct or the xS10.

Thanks!

Hello,

I tried to connect an NeuronxS10 via Modbus RTU to fhem and get it now working. That means I can switch the relay 1 to 8 and can read all DI.
I use coils to read and write. Here is my code from fhem if anyone wants to try it:

Thank you, that works. With the ID 15 I can now connect from RPi3 via mbpoll the xS10. But I can't get it work on FHEM. So is there an example how to define the modbus etc. on FHEM to connect the xS10 via Modbus RTU?

Hello,

I try since some days to communicate from an Pi3 with FHEM via an USB/RS485-adapter to a Neuron xS10 via Modbus RTU. From an Win10 PC I get a connection to the Neuron xS10 with the following parameters Device ID 0, Adress 15 and Baudrate of 19200, 8 Bits, Parity none and 1 Stop Bit. With the tool mbpoll on the Pi3 I can't get a connection because a Device ID 0 isn't accepted (range is from 1 to 254). So I think the problem is the 0 ono Device ID. Is there an option to change the Device ID? Or has anybody another hint for me how I get it work. Thanks a lot!
