A door sensor can do much more than send an open/close alert.

With a Zigbee2MQTT door sensor, a simple door or window event can become a trigger for Home Assistant automations turning on lights, sending security alerts, or pausing HVAC when a window is left open.

We re curious how the community is using door sensors beyond basic security.

What s the most useful automation you ve built or would like to build with a door sensor?
