Aqara Zigbee Temperature and Humidity Sensor 3-Pack — Compact Thermometer Hygrometer with Pressure, Replaceable Battery

The Aqara Zigbee Temperature and Humidity Sensor 3-Pack is a compact smart sensor that measures temperature, humidity and atmospheric pressure and integrates with an Aqara Hub for real-time monitoring and home automations.

This three-pack of pocket-sized sensors gives you continuous environmental data across multiple rooms. Each unit communicates over Zigbee to an Aqara Hub (sold separately), streaming temperature, relative humidity and barometric pressure to the Aqara app where you can view trends, receive alerts and trigger automations with other Aqara devices.

How accurate and reliable are these sensors?

Each sensor uses a high-quality Sensirion module for precise readings and stable performance. Measurements update in real time to the Aqara app, letting you track small changes and identify trends over days or weeks. Keep sensors away from extreme environments like refrigerators for best accuracy.

• Temperature, humidity and pressure reported continuously to the Aqara app
• Industry-leading Sensirion sensing element for consistent readings
• Replaceable battery design — remove the cover to change cells when needed

What connectivity and hub requirements should I know about?

These sensors require an Aqara Hub (not included) to connect into your smart home; third-party hubs and Zigbee USB dongles are not supported. For a stable Zigbee link, place sensors within about 10 meters (33 ft) of the Aqara Hub, and ensure the hub and your Wi‑Fi router share the same LAN for reliable remote access and cloud features.

• Aqara Hub required — not compatible with other-brand hubs or Zigbee2MQTT
• Keep sensor within ~10 meters (33 ft) of the Aqara Hub for robust Zigbee connection
• Hub M2/M1S/E1/M1S Gen2 and certain camera hubs need a secured 2.4 GHz Wi‑Fi connection

How can these sensors automate my home and notify me?

Use the Aqara app to set thresholds and notifications—if a room becomes too hot, too humid or pressure shifts, the sensor can send push alerts or trigger other Aqara devices. Link a sensor to an Aqara Smart Plug, humidifier or night light to create automatic comfort actions without manual intervention.

• Push alerts to phone when set thresholds are exceeded
• Trigger Aqara smart plugs, lights or other accessories for automatic responses
• Historical graphs in-app help refine automation thresholds over time

How do I install and maintain the sensors?

Installation is straightforward: pull the battery tab, long-press the reset button to pair via your Aqara Hub, then mount the unit using adhesive or a small screw. For continued performance, periodically check battery level and replace the cell if the device disconnects or stops reporting.

• Pull battery tab before initial pairing; long-press reset to start pairing
• Rotate sensor to remove the battery cover for replacement when needed
• Do not place inside appliances or extremely hot/cold areas to protect the sensor

Who is this for? The Aqara Zigbee Temperature and Humidity Sensor 3-Pack is ideal for homeowners, renters and smart-home builders who want multi-room environmental monitoring without complex wiring. It suits anyone who needs unobtrusive, reliable readings and wants to link temperature or humidity changes to automations—such as controlling fans, humidifiers or smart plugs—via an Aqara Hub. If you already use Aqara hardware or plan to build a Zigbee-based smart home, this three-pack offers flexible placement and easy integration for ongoing comfort and insight.
