Device Locate is a feature that enables an audible buzzard/alarm to sound off on the unit. The device locate feature can be used to find where in the room the device is hiding. The Device Locate can be found on the device web server page, under Status -> Device.
On the CM4-Pro this is controlled by GPIO 25, on the CM4-Nano GPIO6.
The Device Locate GPIO can also be triggered from within Node-RED using the 'Device Locate node' (coming soon).
It can also be called programmatically using a Node-RED package such as 'node-red-node-pi-gpio'. When using node-red-node-pi-gpio, be sure to initialize the state of the buzzard pin state to low, which will prevent the buzzard from sounding off continuously on a restart.
Developer Note: if triggering the buzzard from node-red or c#, the state will not reflect on the web page. This will be resolved soon.
