Howdy,
If you were to VPN into your home network and be on the same IP it might work. I had some issues across networks and I never got a fix resolution; just keep the devices on the same network (MIND docker container is the same).
I have two WiFi APs that are on different IP subnets. They both connect to a router that routes traffic between them. When the remote was on Wifi-A and the Hexa on WiFi-B I wasn’t able to control it, nor communicate with it via the SDK container. Although I haven’t updated my firmware/app in awhile. Maybe you’ll have better luck than I did.
