Works as expected

Notifying when door is open, left open and closed

Alert when door is left open

When door is not properly closed and left open for a specified amount of time the sensor can send an alert message to your smartphone. If you are not in bluetooth reach with your smartphone it can send the message using the switchbot hub.

The sensor can detect somebody entering (no movement, opened, closed, movement) or exiting (movement, opened, closed, no movement) using the motion sensor, but it will not recognise if the door is being answered (movement, opened, closed, movement).
