I keep getting an error when trying to use AppDaemon and Switch_Reset

Here is the error I get:

Here is my apps.yaml file:

Switch Reset:
  module: switch_reset
  class: SwitchReset
  file: /home/mgranger/.homeassistant/switches.db
  delay: '5'
  log: '1'

seems that the filerights from the file /home/mgranger/.homeassistant/switches.db are not enough for the appdaemon user.
the appdaemon user has probably no writing acces in the dir where you want the db created.

Same problem. I am sure appdaemon has proper rights @grangemd did you ever solved (2017)

4

appdaemon from 2017 was a complete different program then appdaemon now.
so most likely its not the same problem.

and if you use an app from 5 years old, it can be all kind of things.

Thanks for replying @ReneTode I solved by introducing a terminate function closing the db
Here is the updated code

import hassapi as hass
import shelve

#
# App to reset input_boolean, input_select, input_number, input_text to previous values after HA restart
#
# Args:
#
# delay - amount of time after restart to set the switches
#
#
# Release Notes
#
# Version 1.0:
#   Initial Version
