[Part of the SwitchBot Ecosystem] Connect this sensor with other SwitchBot products to create a scene. When you come home, the lights will turn on automatically, and Alexa can say "welcome home." When you leave, the indoor camera will turn on to monitor indoor activity.

[Remote Notification] Get a notification if someone enters your home while you're away, as long as you have the SwitchBot hub.

[Energy and Money Saving] The sensor can detect when you're not in the room and automatically turn off the lights, saving you energy and money.
