ResetZHASensor

This project was heavly inspired by WernerHP's Aqara Motion Sensors AppDaemon app. Many thanks to WernerHP for the original idea and implementation.

Introduction

ResetZHASensor is an AppDaemon app for Home Assistant designed to manage Xiaomi Aqara motion sensors in a Zigbee Home Automation (ZHA) setup. It works in conjunction with a hardware modification that allows the sensors to detect motion every 5 seconds. The app resets the sensor states in ZHA after a specified timeout, enabling the sensors to toggle state every few seconds. This approach helps avoid 'ghost' motion events caused by state desynchronization between Home Assistant and ZHA, ensuring accurate motion detection.

Please note that a hardware modification to the Xiaomi Aqara motion sensors is necessary for this app to function as intended. The hardware modification allows the sensors to detect motion more frequently than they do by default. Without this modification, the sensors would only be able to detect motion every 120 seconds.

HACS Installation

1. Make sure you have the option "Enable AppDaemon apps discovery & tracking". This is located in: Configuration -> Integrations -> HACS (options).
2. Restart Home Assistant.
3. Go to HACS -> Automation -> search for "ResetZHASensor" and install it.
4. Follow the app configuration section below.

Manual Installation

Download the reset_zha_sensor directory from inside the apps directory to your local apps directory, then configure the reset_zha_sensor module in apps.yaml.
