Received a Remotec ZXT-600 today to control the airco in our living room and defined the following:
If the temperature gets above 25 degrees in the living room and the outside door and window are closed, then, if the TV is on, a message shows up on the TV to ask if I want the airco on.
And if I press the OK button on the TV remote, the airco indeed turns on.
I just love the way I can connect all my devices using Indigo.
