Hassio appdaemon 4 import

Third party integrations AppDaemon
1

Hi, have searched the web and this forum to try and find how a get appdaemon to install a python package. The import on my python app fails as it can’t find the import. I found some reference to


python_packages:
  - httplib2

but it doesn’t seem to work in either appdaemon .yaml or apps.yaml
Please advise where I tell appdaemon that I want top import a python package.
Welcome any help,
Cheers David

Just make a text file named requirements.txt and put it in your conf folder, same folder where your appdaemon.yaml is.

Then list the python packages in the text file with the required version, i.e.

httplib2==0.18.1

Appdaemon will pip install them on startup.

See here: https://appdaemon.readthedocs.io/en/latest/DOCKER_TUTORIAL.html?highlight=requirements.txt#adding-dependencies

Thanks for you fast reply Tomas.
Have tried adding requirements.txt containing the single line you suggested
Have placed that in the same folder as the appdaemon.yaml
have restarted appdaemon and tried restarting Home Assistant fully - unfortunately it still errors:

I am running version 0.117.1of HA and AppDaemon 4 version: 0.3.1
To test I have merely added the import to the hello.py:

import appdaemon.plugins.hass.hassapi as hass

import httplib2
#
# Hellow World App
#
# Args:
#

class HelloWorld(hass.Hass):

  def initialize(self):
     self.log("Hello from AppDaemon")
     self.log("You are now ready to run Apps!")

Thanks for your help again - there must be a simple answer
Cheers David

Found the answer: for anyone trying to import Python packages on AppDaemon 4 under HASSIO.

  • In Hassio go to supervisor (menu on left hand side) and click on the add-ons AppDaemon 4
  • at the top of the page there is a configuration tab - click this
  • here you can add python packages - for example:
system_packages: []
python_packages:
  - httplib2==0.18.1
  - untangle
init_commands: []

hope this helps someone.
Cheers David
