Can't get plugwise Stretch plugin to work on Synology

[WillemV]

I have a Plugwise Smile and a Stretch which I want to read and log on my Synology NAS.

According to this article that shouldn't be too hard: https://www.domoticz.com/wiki/Plugins/Plugwise
I thought that if I could get this going for the Stretch then that should possibly also work for my wireless P1-Smile.
However I can't get it to work. See the logging below:

1) From Startup Path: /usr/local/domoticz/ the path "plugins/Plugwise/log.txt" does not appear right. In my eyes it should be: "var/plugins/Plugwise/log.txt"
But after correcting is the results remain the same.

2) It looks like the logfile cannot be created. But after manually creating a log.txt in this location I stil get the same log messages.
Is the code correct? I don't know much about Python but the code seems to be ok.

3) Could it be a rights issue? I assume that on the Synology the script is being executed by the root account. Installation however was done by user 'domoticz'.
I changed the owner of all folders and files to owner 'root' recursively. That also didn't help.

Does anyone have any ideas or even experience with this issue?
I am running out of clues here.

NAS: Synology DS218play, architecture: rtd1296 (armv8)
Domoticz: V2020.1, package: domoticz_rtd1296-6.2_4.0.10717-8
Python version '3.8.2'

Any help would be much appreciated.

I think my approach hasn't been correct.
Instead of trying to read data from the Plugwise P1-Smile from the Synology NAS I should replace the Smile with a Raspberry Pi altogether.
And run Domoticz from there.

After that I will could figure out a way to use my NAS for backup.

I use this plugin on an openSUSE Leap 15.2 Raspberry Pi 4B system and had the same type of error messages. The reason was that domoticz runs as user domotics and group domoticz. I assume that is the same on Synology. Changing file protection on domoticz files to be owned by root does not change the user/group under which domoticz runs. My solution was to change ownership of all files in the folder plugins to domoticz/domoticz. In that case domoticz is able to create log.txt in .../plugins/Plugwise/ etc.

Hello

I am new to this forum. I use Domoticz from 2013.
I have the plugin wiki/Plugins/Plugwise working in a VM Debian 10 and Raspberry PI.
I can't get it to work in docker.

Other plugins as Buienrader, Somfy Tahoma ,Growat Web plugins do work properly

Jus can't get this one to work

I got the following error messages
Can somebody help?
I can't find any forums about this problem

[waltervl]

You did not post the error messages.
Are you getting the plugin hardware in the hardware list?
Isa the USB connection correct with Docker Container?
Did you enable debug? Did you get the devices.json file and the debug log.txt file in the plugins/Plugwise folder?

[InControl]

Thank You for responding

Yes the plugin is in the hardware list.
There is no USB because it read out the Plugwise stretch with JSON
Debug is on


Error log is as follow

Seems that the debug function is causing the issue
Looks like the plugin is not able to create the log.txt file in the plugins/Plugwise folder.
Perhaps switch off debugging for now.

As the plugin also wants to create a devises.json in the same location perhaps it also gives issues....


Are there also other errors when starting the plugin? Click on update will restart the plugin.

Hello

even wen I have the debug funktion off , errors are the same.

I did send a full copy off the error messages, so no more other issues about the plugin.

[waltervl]

OK. Check the previous comments from the other users about access rights of the plugins/Plugwise folder....

[InControl]

Ok

did some check's

First made the userdata accesrights root => this also mentioned in the posts that this does not work

Added a docker user to the filesystem => made this user member of the docker group => set file permissions to Dockeruser => also did not work

What I not do understand is while Domoticz is running in a container, outside the container there is no Domoticz user and group
So how do I set permissions to this user/group?
Do I have to create one at the host machine?
