dzVents error 3.1.8

[BartSr]

Hi,
After I started up my systems I got next error which never occured before. Any Idea how to deal with?
By the way: is there somewhere an overview explaining the error messages?
Thanks

Maybe it could be a disk space issue?

[willemd]

My guess is that the folder for the persistent variables is somehow not accessible.
Check the folder $HOME/domoticz/scripts/dzVents/data

Check this page
https://www.domoticz.com/wiki/DzVents:_ ... stent_data
and then scroll down to "how does the storage stuff work"

Are you using docker? As that also needs sometimes special considerations on folders.

Are you using docker? As that also needs sometimes special considerations on folders.

I'm getting the same error and I'm using docker version (installed the way from here: https://github.com/domoticz/domoticz-docker)
In docker there where no /opt/domoticz/dzVents/rest_of_the_files_and_folder / where also there should be the missing persistance.lua.
I created those by hand, as well as the missing /opt/domoticz/userdata/scripts/dzVents/data/__nameofthescript.lua but the error still pops up.

How to fix this ?

I suppose there are missing paths in the docker-compose.yml file to get the dzVents storage function to work, yes ?
Mine looks like this:

Code: Select all

version: '3.3'

services:
  domoticz:
    image: domoticz/domoticz:stable
    container_name: domoticz
    restart: unless-stopped
    # Pass devices to container
    # devices:
    #   - "/dev/serial/by-id/usb-0658_0200-if00-port0:/dev/ttyACM0"
    ports:
      - "8080:8080"
    volumes:
      - ./config:/opt/domoticz/userdata
    environment:
      - TZ=Europe/Warsaw
      #- LOG_PATH=/opt/domoticz/userdata/domoticz.log

For docker it is important to set user access correctly.
Add the current user (eg Pi) to the docker group with

Code: Select all

sudo usermod -aG docker ${USER}
