Wireguard | Toggle on for mobile data and off for home Wi-Fi

[random king]

I have configured a Wireguard connection to my home router. 

I would like to toggle on the Wireguard tunnel whenever I switch to mobile data and then toggle off the Wireguard tunnel whenever I connect to my home Wi-Fi. 

Is that possible without Root?

Try Broadcast send block...

• Package: com.wireguard.android

• Receiver class: com.wireguard.android.model.TunnelManager$IntentReceiver

• Action= "com.wireguard.android.action.SET_TUNNEL_UP"

• Extras: { "tunnel": "<name of tunnel goes here" }

See: https://github.com/WireGuard/wireguard-android/blob/master/ui/src/main/java/com/wireguard/android/model/TunnelManager.kt

You also need to grant the "control WireGuard tunnels" privilege. The "Receiver class" is probably optional.

Something, I just discovered.  If I start the service in automate, then, after the error pops up, manually connect the Wireguard VPN, then turn on my wifi to connect to my named wifi network, the Automate service will turn off the Wireguard connection.  Then, as long as I don't manually manipulate anything else, if I lose Wifi on that network again, it WILL connect to Wireguard and not throw the error.  

I have no clue why this is, but it works.  So, basically it looks like for this to work, you need to manually connect to Wireguard the first time, then (assuming you'll have to do this after every reboot) after that it should continue to work.
