Third party integrations AppDaemon

Hi all,

Does anyone know how i can use additional python libraries?
Using HassIO with AppDaemon and trying to import pycurl for example.
I get a message that this module is not available, but how can i add this??

You need to include it in the python_packages portion of the add-on config:

{
  "log_level": "info",
  "system_packages": [],
  "python_packages": [
    "pycurl"
  ]
}

Thanks for the quick response, looks like this is what i was searching for.

Tried to add the package but i guess it needs additional system packages.

right, pycurl needs a lot of extra.
there where more attempts from people here on the forum, and it took them a while to figure out what all was needed.

Any solution to have my own package used instead ? Any way for instance to copy past the content of my site-package to the one fetch by AD ?

Hi there. Just been through this myself for a custom python app. The solution to pycurl is here Dahua IPC to MQTT App - #55 by xbmcnut

That was what i tried to acchieve, but i was missing the pycurl library inside the AppDaemon apps. I’ve searched for the packages needed and this is how i got it working:

{
  "log_level": "debug",
  "system_packages": [
    "curl-dev",
    "python3-dev",
    "libressl-dev",
    "musl-dev",
    "gcc",
    "libcurl"
  ],
  "python_packages": [
    "pycurl"
  ]
}

When it worked i started rewriting the application since i do not use mqtt, but just want to notify my devices including a snapshot

What my setup does is the following:

  • Camera has an event (CrossLineDetection for example), takes a snapshot and stores it on a share
  • AppDaemon reads camera events and get triggered with the help of pycurl
  • AppDaemon takes the event time from the camera data and uses this to find the correct snapshot
  • AppDaemon calls the notify services and send the snapshot including information to my tv’s and phones

My previous setup was getting the snapshot from the camera directly, but sometimes the object was already gone so this was no option for me.
