# Matter ESP32 Lock Example

This example demonstrates the mapping of OnOff cluster to lock/unlock logic.

Please
[setup ESP-IDF and CHIP Environment](../../../docs/platforms/esp32/setup_idf_chip.md)
and refer
[building and commissioning](../../../docs/platforms/esp32/build_app_and_commission.md)
guides to get started.

### Cluster control

#### onoff

To use the Client to send Matter commands, run the built executable and pass it
the target cluster name, the target command name as well as an endpoint id.

    $ ./out/debug/chip-tool onoff on <NODE ID> 1

The client will send a single command packet and then exit.

### Example Demo

This demo app illustrates controlling OnOff cluster (Server) attributes of an
endpoint and lock/unlock status of door using LED's. For `ESP32-DevKitC`, a GPIO
(configurable through `LOCK_STATE_LED` in `main/include/AppConfig.h`) is updated
through the on/off/toggle commands from the `python-controller`. If you wish to
see the actual effect of the commands on `ESP32-DevKitC`, you will have to
connect an external LED to GPIO.
