Internal Error (500) after fresh Evok installation
-
I got Neuron unit and try to bring it to life, but I got stuck at the moment when I installed Evok on it. It seems to work, there are no conflicts, but any call, such as http://my_address/rest/all ends in "{"status": "error", "message": "Internal Server Error", "code": 500}" reply. Not sure what could go wrong, and the documentation gives me any hints. Anybody has any idea what could be the reason for this ? Thanks.

I also noticed that I can't stop Evok service the way it is described in the Github (debugging section). I get "Failed to stop evok.service: The name org.freedesktop.PolicyKit1 was not provided by any .service files" - does this mean that Evok was not properly installed ?
On top of that, I have the log file full of the following error :
2017-11-07 23:10:21,222 - evok - ERROR - 'NoneType' object has no attribute 'do_scan'
Traceback (most recent call last):
File "/opt/evok/neuron.py", line 217, in scan_boards
yield self.modbus_cache_map.do_scan()

Hi @actiwerks!
The second error often happens because the systemctl command requires root privileges; you can fix it by running "sudo su"
(sans the quotes) before the "systemctl stop evok" command (and any other time the "org.freedesktop.PolicyKit1" error appears). It is a general linux issue, which has nothing to do with EVOK as such.As for the first issue, it looks like EVOK can't see your Neuron at all. It would help to have three diagnostic files; could you please post (ideally by uploading to https://pastebin.com/ as they are rather long) the output from "python /opt/evok.py", your "/etc/evok.conf" file, and the output from "ps -fax"?

Hi,
I have same issue with M103
evok.conf -> https://pastebin.com/kqbXDD7D
...and
python evok.py -> https://pastebin.com/eBz9v4w6

From the log it looks like your I2C EEPROM module is not working correctly. The type of your Neuron device is stored in the EEPROM, and without it EVOK can't tell which model you have.
If you run the "cat /sys/bus/i2c/devices/1-0057/eeprom" command, do you get a valid reply? It should look something like this (for L513):
�������������������������������������������������������������������������������������������������U�L513������������������#The file is editable as well, so you should be able to change the id string characters to "M103" to get it to work
Edit: Please use the code button (end of the compose post bar) if you do post the output here, as the characters break forum formatting otherwise.

Hi Tomas,
Thank you for quick reply.
My /sys/bus/i2c/devices directory has only i2c-1 -dir.....weird!

Could you post the output of "i2cdetect 1" and "lsmod"? It does look like the EEPROM isn't available for some reason.

I made fresh Rasbian install (RASPBIAN STRETCH LITE, 2017-09-07) and also fresh Evok install with these instructions:
sudo su wget https://github.com/UniPiTechnology/evok/archive/master.zip unzip master.zip cd evok-master bash install-evok.shThat Nginx based interface works fine but when i try use Evok rest api with terminal i get error:

The id numbering scheme is x_yy, with x being the group (1,2,3) and yy being the id (i.e. 1_01 for the first relay).
Anyway from your i2cdetect (and the fact that EVOK runs as well) it looks like the EEPROM works fine now.
You can read more about the numbering in our EVOK documentation, subsection on "Note regarding device addressing" on the introduction page: https://evok.api-docs.io/1.0/jKcTKe5aRBCNjt8Az/introduction#note-regarding-device-addressing

Aaaa....ok
wget http://localhost:8080/rest/relay/2_01Yep...this works fine!
So....how about Evok 2 with UniPi 1.1? Is there any plans to update that principle to UniPi 1.1?
Thank you!

@Vesa-Kauppinen
Glad to hear it works now!EVOK 2.0 should work fine UniPi 1.1, but obviously much of the extra hardware functionality which Neuron has will be missing.
The UniPi 1.1 also has an EEPROM, it's just in a slightly different format. The reason that the installation needs to know which hardware you have is that we need to install certain different libraries to get the hardware to work correctly. Unfortunately this cannot be done automatically, as the EEPROM is not loaded during the installation yet.
