How to Set Up Your Aqara TVOC Air Quality Monitor

The Aqara TVOC Air Quality Monitor tracks volatile organic compounds, temperature, and humidity in your home environment. This compact Zigbee sensor pairs with your Aqara Hub and provides real-time air quality data through the Aqara Home app, helping you maintain a healthier living space.

What You Will Need

• Aqara TVOC Air Quality Monitor
• Aqara Hub (M2, M3, or Camera Hub G3) already set up on your network
• Aqara Home app installed on your smartphone (iOS or Android)
• CR2450 coin cell battery (included)

Preparing the Sensor

1. Remove the Aqara TVOC Air Quality Monitor from its packaging.
2. Pull the plastic battery isolation tab from the back of the sensor to activate it. The e-ink display should light up briefly, confirming the battery is connected.
3. If the display does not activate, open the back cover by pressing the release tab, remove the CR2450 battery, wait 10 seconds, and reinsert it with the positive side facing up.

Pairing with Your Aqara Hub

1. Open the Aqara Home app on your smartphone.
2. Tap the + icon in the upper-right corner to add a new device.
3. Select TVOC Air Quality Monitor from the sensor list, or scan the QR code on the device packaging.
4. Choose the Aqara Hub you want to pair this sensor with.
5. Press and hold the reset button on the back of the sensor for 5 seconds until the display flashes, indicating the sensor is in pairing mode.
6. Wait for the app to discover and connect to the sensor. This typically takes 10 to 30 seconds.
7. Once paired, assign the sensor to a room and give it a descriptive name such as "Living Room Air Quality."

Choosing the Right Location

Placement significantly affects the accuracy of your air quality readings. Follow these guidelines for the best results:

• Place the sensor at breathing height — on a desk, shelf, or nightstand rather than on the floor or ceiling.
• Keep it away from windows, air vents, and fans to avoid skewed readings from direct airflow.
• Avoid placing it in direct sunlight, which can artificially raise temperature readings.
• Position the sensor within Zigbee range of your hub, generally within 10 to 15 meters with no more than two walls between them.
• For whole-home monitoring, consider placing sensors in the bedroom, kitchen, and main living area.

Understanding the Display and Readings

The e-ink display shows three key measurements. TVOC is measured in parts per billion (ppb) and indicates the level of volatile organic compounds from sources like cleaning products, paint, and furniture. Temperature and humidity are displayed alongside the TVOC reading.

A smiley face icon on the display provides a quick visual indicator of overall air quality. A happy face means conditions are good, a neutral face indicates moderate levels, and an unhappy face signals poor air quality that may require ventilation.

Setting Up Automations

You can use the TVOC sensor to trigger automations in the Aqara Home app. Common examples include:

• Turning on a smart plug connected to an air purifier when TVOC levels exceed a set threshold.
• Sending a notification to your phone when humidity drops below 30% or rises above 60%.
• Triggering a smart switch to activate a ventilation fan when air quality is poor.

To create an automation, go to the Automations tab in the Aqara Home app, tap +, select the TVOC sensor as the trigger, set your condition threshold, and choose the desired action.

Tips for Best Performance

• Allow 24 to 48 hours after initial setup for the TVOC sensor to calibrate and provide accurate baseline readings.
• The CR2450 battery typically lasts about one year. Replace it when readings stop updating in the app.
• Periodically check for firmware updates in the Aqara Home app to ensure optimal performance.
