Aqara Climate Sensor W100
Monitor, automate, and personalize your comfort—all from one smart, Matter-ready climate sensor with real-time display.
Take Control of Your Home Climate with the Aqara Climate Sensor W100
Stop guessing and simplify your smart home! The Aqara Climate Sensor W100 gives you precise environmental data and seamless integration, exactly the way you need it.
Features
Works Your Way with Matter, Thread & Zigbee: Future-Proof Your Smart Home. Forget about being locked into a single ecosystem. Featuring the latest Matter-over-Thread technology, the W100 integrates effortlessly with leading platforms like Apple Home, Google Home, and Amazon Alexa right out of the box. Prefer the reliability of Zigbee? Connect it to an Aqara hub for exclusive features and enhanced performance. Choose the protocol that suits your home best, ensuring seamless smart home operation today and in the years to come.
Instant Control with 3 Customisable Smart Buttons: Convenience at Your Fingertips. Need to dim the lights, activate your "Cosy Evening" scene, or switch on a fan instantly? Configure up to 9 different actions using single, double, or long presses on the three integrated buttons. Enjoy immediate control over your connected devices and automations without needing your smartphone. It's convenient control, right where you need it.
High-Precision Sensor & Clear LCD Display: Monitor Your Environment with Accuracy. Rely on highly accurate temperature (±0.2℃) and humidity (±2%RH) readings, displayed in real-time on the clear 3.4-inch LCD screen. Easily track conditions to maintain a comfortable and healthy living space, protect valuable items (like musical instruments or plants), or ensure optimal conditions in greenhouses or storage areas.
Expand Your View with External Sensor Integration (Zigbee Mode): Keep an Eye on Multiple Locations. Want to monitor the temperature in the nursery or the humidity in the cellar from a single point? When using Zigbee, connect an additional Aqara Temperature and Humidity Sensor (sold separately), and its data will conveniently appear on the W100's secondary screen area. Monitor conditions in two locations simultaneously, effortlessly.
Smart HVAC Control for Effortless Comfort & Energy Savings: Automate Your Climate. Connect the W100 to an Aqara M3 hub to control compatible infrared (IR) air conditioning units, or pair it with an Aqara thermostat (via any Aqara hub) to manage your central heating and ventilation system wirelessly. Adjust temperature, humidity, and modes directly from the W100 or through smart automations (e.g., "turn off heating if window opens"). Maintain perfect comfort automatically and potentially reduce your energy consumption and bills.
Set It and Forget It: Long-Lasting Battery Performance. Powered by two standard CR2450 batteries, the W100 is designed for long life, lasting up to 2.4 years (Zigbee) or 2.3 years (Thread) under typical use. You can even adjust the sensor's reporting frequency to perfectly balance real-time updates with maximum battery efficiency. Enjoy reliable performance with minimal maintenance.
