Notification to my phone

I have tried to setup HA to notify me if any of the three doors to the house are left open for more than 3 minutes, where it would pop up on my phone and give a badge number on the HA companion app. I think its set correctly, or at least its firing off, but no notification is appearing on my phone’s app. Either my code isn’t correct, or my phone notifications are not setup properly, and I’m pretty sure its not the latter. Any help diagnosing this is appreciated.

You miss the target in the notify service
Check in the developer tools if you have a service like notify.mobile_app_yourphonename

I only have notify and persistent notify.

I don’t see my mobile device in the list of devices…is there a way to get HA to scan for it again?

Try deleting and re-installing the app on your phone - choose a new name for the identification on the phone. After that, restart the HA.
