I want use local only on Companion app on an Android when Internet is down on home network. I have a regular HA setup on an HA Blue and a test system on an RPI4. The regular system uses NabuCasa for external and static IP of HA for internal. I am unable to access the test system unless I disable mobile data on Android. I am unable to access regular system in Companion app no matter what I do with Internet down. I can’t add regular system as new server either. I am able to access regular system in browser on Android phone if I turn off mobile data.
I have deleted data for Companion app and uninstalled and rebooted phone then reinstalled app multiple times. Still can’t access HA with app.
- Is there a way to fix Companion App so I can access regular HA?
- Is there a setting in Android that forces it to use local when Internet through wifi is down but mobile data is on?
