What You'll Need

Aqara TVOC Air Quality Monitor
Aqara Zigbee 3.0 Hub
Aqara Home app
CR2450 battery (included)

Step-by-Step Setup

1. Pair the Monitor

Remove the battery tab to activate the device
Open the Aqara Home app and tap +
Select TVOC Air Quality Monitor
Choose your hub and follow the on-screen instructions
If pairing fails, move the monitor closer to the hub and try again

2. Place the Monitor

Two placement options:

Lay flat on a desktop or shelf
Attach to a wall using the included adhesive backing (magnetic detachment supported)

3. Wait for Calibration

After startup, network connection, or battery replacement, the TVOC value may not display immediately. This is normal—the sensor is calibrating. Allow several minutes for readings to stabilize.

What It Monitors

TVOC (Total Volatile Organic Compounds): 0-25 mg/m³ range
Temperature: 0-50°C range
Humidity: 0-100% RH

E-Ink Display

The integrated e-ink screen shows current readings at a glance without needing to check the app. Low power consumption means battery lasts for months.

Automation Ideas

Turn on ventilation fan when TVOC levels rise
Trigger air purifier when air quality degrades
Send phone notifications when VOC concentration is unhealthy
Combine with temperature/humidity for comprehensive climate automation
