Pretty sure that won’t work since it doesn’t leave a dedicated connection to call back to (unless I read it wrong). TeamViewer and ngrok work because they initiate a connection to an endpoint I can tunnel back through it. Carrier NAT grrr.
I tried setting up softether and their azure VPN service, but couldn’t get it to work.
Anyway, my hubitat arrives tomorrow.
Update : got my hub, and added a few motion sensors. Added all the otherhub code, and the sensors showed up in ST classic. Yeah! Update time is pretty quick, and I was even getting motion updates through a cell connection (hubitat to router to wifi client to phone hotspot). Going to test 2 way connectivity tomorrow to make sure a switch on the hubitat can be controlled by ST.
