Companion app in combination with Deco Mesh System

I’m searching for a solution to use my companion app together with the desktop application. My pc is connected through ethernet, my cellphone is connected to the mesh-system. So they are getting another subnet, and can’t find eachother. My Zwiftapplication works fine, but I can’t choose routes while cycling, I can’t communicate with others. Hope to find a solution…

If you can’t reconfigure the network so that both devices appear on the same subnet, a trivial solution would of course be to put a wlan router between your pc and the ethernet cable and connect your phone to that network instead of the mesh. Not ideal, I know.

(Not sure if they in fact even need to be on the same subnet or if it is enough that both devices see each other’s IP addresses as-is and the ports used are open.)
