I have tried adding a URL action to a button in HomeAssistant to open an IOS app via URL but selecting it does not do anything. I confirmed that I can open actual web pages this way, so it is an issue with the IOS URL concept. The specific app I am trying to open is RoomieRemote. I have verified that the URL (roomie:// ) works from safari to open the Roomie App.
This would allow me to put a RoomieRemote button on my HomeAssistant IOS interface to start RoomieRemote. (I have already added a button in RoomieRemote to start HomeAssistant). This way whether a user starts in HA or Roomie they can do room automation via HA and Media/Video control via Roomie.
Is there a way that I can do this or does the CompanionApp need to be updated to support?
