Turning the TV on and off is very simple. You just have to press you the power button on the TV Box remote control. When you turn the TV off this way, the TV will display a picture (like a painting). This picture will disapear 5 minutes after you leave the room. Alternatively, you can press and hold the power button on the TV remote to force the TV to turn off.
Netflix is available from the main menu of the TV box. All you need to do is highlight the Netflix button using the arrows on the TX Box remote control, then press the OK button. Then select the "Guest" profile.
To change the language or subtitles, use tho "OK" button of the TV Box remote control.
To go back to the main menu of the TV Box, use the "Menu" button.
The house is equiped with two Google speakers (one in the ground floor bedroom, and on in the main room at the first floor). You can ask Google anything you want, just say "OK Google" (for example: "OK Google, let's play some music").
If you want to cast some music from your phone, just say "OK Google, switch bluetooth", then search and connect either to the "hub" or "speaker" device.
It is important to note that these Google devices are configured for the French language. Google will understand you if you speak English, but will always respond in French.
