    Turn on the first switch for about 10 minutes, turn it off, turn on the second switch, don't turn on the third, and then go into the house. Look at a light that's on, a light that's not on in the heat, and a light that's not on, that's it.

    One entry is enough.

    You're asking the wrong place. Hehe, here's the decoration.

    It's so cute.

    Press the switch the first time you enter the door, turn on a light, mark the switch when you come out, and mark any of the remaining switches at the same time, enter, and remember which light it is.
