Ah, ok. You'll want to specify two allowedip ranges on the clients, 192.168.178.0/24 for your network, and 10.0.0.0/24 for the other clients. Then your going to need to add a couple of routes:
On the phone, a route to 192.168.178.0/24 via the wireguard address of your home server
On your home network router, a route to 10.0.0.0/24 via the local address of the machine that is connected to the wireguard vpn. (Unless it's your router/gateway that is connected)
You'll also need to ensure IP forwarding is enabled on both the VPS and your home machine.
