AppDaemon apps are apps for AppDaemon
Since not all users are running AppDaemon, AppDaemon is not enabled by default in HACS.
AppDaemon Has to be installed before doing the configuration with HACS.
There are 2 ways of doing this.
Add a checkmark to the left of AppDaemon apps in the UI configuration for HACS.
If you used YAML to configure HACS, add this under your HACS configuration to enable AppDaemon apps:
hacs: ... appdaemon: true
After adding that you need to restart Home Assistant.
Any AppDaemon app downloaded with HACS is stored in
appdaemon/apps/ in your Home Assistant configuration directory.
