COSMOTE TV Smart Remote application allows you to control your Set-Top-Box (STB) (provided that you are a COSMOTE TV subscriber) using your smartphone or tablet as you are currently doing with your remote control.
In order to communicate the device with the STB, the following requirements must be met:
a) the stb should be connected to the internet and
b) the device should be connected to the same local network (same wifi) as the STB.
