Im not a fan of the new St Ui but having said that i very much appreciate the Tv Source option as a condition 
Ip cam to pc - pc to tv via 5mtr Hdmi cable
Ext dumb movement sensor to power sense pocket socket
On movement after dark ext sensor triggers power draw at pocket socket turns on ext security lights
And now changes tv source to correct input immediately on tv
All with the help of the tv condition options
If we could get the missing switch on function working that would be the cherry on the cake, i could easily set up turn tv on if door knocked
Thank you Smartthings
