Do I need a SwitchBot Hub to use it?

Yes. The sensor talks Bluetooth, and the SwitchBot Hub bridges it to the app, voice assistants and other devices. Without a hub you get only a local Bluetooth connection.

Can it be used outdoors?

It is IP54-rated, which covers splashes and dust. Mount it under cover, not in direct rain, and keep it within range of the hub.

What batteries does it take?

It runs on standard disposable batteries, so keep a spare set on hand. Battery life depends on how often it triggers and how far it sits from the hub.

Does it work with Alexa and Google Home?

Yes, through the SwitchBot Hub. You can use voice commands to check status or include the sensor in routines with other SwitchBot devices.

Is $42.43 a good price?

It is the only new price we have, $42.43 at The Home Depot as of November 7, 2026, so there is no recent range to judge it against. Compare it with bundle prices if you also need a hub.
