My SmartThings v2 Hub is connected to one of the ethernet ports of my WiFi router (so has 192.168.1.x style address). While at home and in-range of my WiFi router, does the mobile app communicate directly to the hub (app -> local wifi -> hub) or does it go via the SmartThings cloud service (app -> internet -> cloud -> internet -> hub)?
I am thinking of moving my v2 hub off my WiFi router and connect it to the cable modem ports. If the communication is local (app -> hub) then I would loose that functionality (and would rethink my strategy).
If there is a page about how app/hub v2/cloud interact network wise, I’d be happy to read that instead.
