Lounge TV
The main remote control is the black Samsung one. You'll also find there a remote for the Samsung Soundbar - it says "Soundbar" on it, helpfully.
If you want Sky, use the Apple TV set up. It's the silver remote I am holding in the photo here. If you just click on the TV icon next to my thumb in the pic, it puts on the Apple TV.
If a screen comes up with log in icons, choose mine. Once it's loaded,
Top Bar Room TV
Again, it's the same set up as in the lounge. You can either watch mainstream TV or find Sky on Apple TV.
Alexa Lights
There are Alexa devices throughout the house.
LOUNGE LIGHTS NEXT TO THE TV - these turn on by just saying "Alexa, turn on the lights", when you are in the lounge. Similarly, they turn off by saying "Alexa, turn of the lights", when in there.
TOP BAR ROOM LIGHTS - these work in the same way as the lounge lights, above, when you are in the top bar room.
HALLWAY LIGHTS - these operate by asking the Alexa in the kitchen "Alexa, turn on George House Hallway Lights". Again, they turn off by saying "Alexa, turn off George House Hallway Lights".
