Check Mobile App Integration:

For Remote access to the Mobile app (Companion App), you can use one of the following;

• Port Forwarding on your router to Port 8123 of your local Home Assistant IP address. Use a dynamic DNS service eg noip.com or dyndns so you can access by a fixed URL.
  
• Home Assistant Cloud which gives many more features, line connect with the Voice Assistant see https://www.nabucasa.com/ It costs a small amount paid month or yearly but has a 1 month trial period
• Use a Virtual Private Network (VPN) 
  

I have tried the 1st 2 options, but not the VPN as that seems more complicated


In the Home Assistant App, you can specify several Servers eg Home, Office, Home Remote, Office Remote with different IP addresses. In the Home Assistant Companion app you can select the server in Settings > Cmpanion App (but this is not on the Desktop client)

The notification on the Mobile phone is shown for system armed





The notification by SMS is also seen before that
