I was looking at cheap Wifi controlled sockets on Ebay,
Smart WiFi Remote Control Timer Switch Power Socket Outlet US Plug for Cellphone
then I looked up a video to explain how they worked..

When they showed the app, I realized it was the same Broadlink app
that I downloaded last night, to get some idea how the Broadlink RM2 Pro "Hub thing" worked..
2016 Broadlink RM Pro WiFi Wireless Remote Control Home Automation Kit Black US
Strange, the same app for both devices..
Edit: I saw the Broadlink shipping for $30 from NJ, so I placed an order..
I think this thing might be able to operate our 315 MHz GDO..
