Would be great to have the ability have mobile devices automatically open the mobile app using URL Schemes/intents. I was able to modify the config_validation.py to test the feasibility and it works well for iOS (still needs tweaking for Android). Here is an example for Plex:
weblink:
entities:
- name: Plex-iOS
url: ‘plexapp://test’ #test required to get past validation
icon: mdi:router-wireless
- name: Plex-Android
url: ‘intent://plexapp/#Intent;scheme=plexapp;package=com.plexapp.android;end’
icon: mdi:router-wireless
