I just got my Aqara FP300 Presence Sensor set up in Home Assistant. I set the sensor up in the Aqara app as a Zigbee device, then closed the app once it had finished changing it to Zigbee. In Home Assistant, I installed two apps: 1: MQTT Mosquito Broker, and 2: Zigbee2MQTT. I paired the Fp300 using the Zigbee2MQTT “Permit Join” function.
After that, I created an automation that uses the PIR or Presence Sensor (either) to turn on a Smart Plug that controls a light. Only the FP300 Presence sensor can turn off that Smart Plug (I chose this because the PIR sensor kept staying on 2 minutes after I left the room, and I wanted the light to shut off sooner if no one was in that room). I also added a 20 second timer so that if the PIR detected something, but the Presence Sensor did not (such as me starting to walk in that room, but turning around), the Smart Plug would still be turned off 20 seconds later.
Here’s the automation:
- alias: "Bathroom Light Strip (FP300 PIR + Presence Control)"
description: >
PIR turns ON quickly. Presence turns ON slower. Presence controls OFF.
If no presence detected within 20 seconds after PIR,
light turns OFF automatically.
