There is a row of string lights on the outside deck that should come on automatically at 5:30pm and turn off at 10pm.
You can also turn these on and off yourself to override the automatic function by:
Saying to the Alexa speaker (near the dining room table, under the large picture) "Alexa, turn on the deck lights." or "Alexa, turn off the deck lights."
Or, just press the round button on the white deck light timer box that is plugged in outside on the deck just to the right of the mini fridge.
