Can be used to trigger a occupancy detected event when a switch is turned on, via Siri for example.
npm install -g homebridge-occupancy-switch
And add the following to the accessories list in your Homebridge config. Change names as you wish.
{
"accessory": "Occupancy Switch",
"occupancy_sensor_name": "Occupancy Sensor",
"switch_name": "Occupancy Switch",
"name": "Occupancy Switch"
}
Then add it to HomeKit, once added, you will need to turn on Notifications for the Occupancy sensor you just added.
