Contact Sensor.

OverviewSwitchBot Contact Sensors are two parts attached to things like windows and doors. With a distance of up to 16.4 feet (5m) and 90deg horizontally and 55deg vertically, every movement the window or door makes will be detected and inform you of contact. Align the magnet’s area to the bottom of the SwitchBot, the contact sensor’s main body, and you’ll be good to go. Receive notifications around the time. Connected via SwitchBot Hub, Mini SwitchBot Contact Sensor can send notifications to your phone whenever someone comes into your home if windows are open or your pet is released from its cage. Put the Contact Sensor in any window or door. Your home’s security will be protected by this first line of defence that will be alerted in a matter of seconds, even when you’re away from home. Use audio alarms. If linked via SwitchBot Hub Mini, your intelligent voice assistant will inform you of events like when someone comes into your home or a door is open—staying on top of home affairs regardless of whether you’re inside a separate space around the house or if you’re on the go. Alexa and Google Home currently do not support Contact Sensor’s light-level sensor or motion-related features. However, the quality is being supported by IFTTT.
