Compact wireless temperature and humidity sensor for Xiaomi/Aqara smart home control
- unknown room temperature and humidity levels
- manual climate adjustment
- need for wiring in smart home setups
Know your room's climate and let your smart home handle the rest
Stop adjusting the AC by feel and guessing at humidity. This compact wireless sensor reports real readings to your Mi Home app so your air conditioner can respond automatically.
Wireless sensing that fits your existing setup

Wireless Zigbee link
Zigbee carries each reading from the sensor to your Xiaomi or Aqara hub, so nothing needs to be drilled, clipped or run along the wall. Set it on a shelf, pair it in the app, and the numbers start arriving in Mi Home.

Built for Mi Home setups
Temperature and humidity show up in the Mi Home and Aqara apps, next to the lights, plugs and sensors you already control. If your ecosystem is running, this one joins it without a separate app to learn.
Runs your AC on its own
The sensor works with an air conditioning controller to adjust temperature and humidity automatically. It supplies the room readings and the controller acts on them, so the room holds its level through the day and overnight. If humidity is the bigger problem, you can also browse dehumidifiers for the same room.
Pair it once, then place it right
- 1Pair with your hub
Add the sensor in the Mi Home or Aqara app and follow the pairing steps until live readings appear for the room.
- 2Pick the spot
Set it on a shelf or table at seating or bed height, away from the AC vent, windows and heaters.
- 3Link it to the AC
Build an automation in the app that uses the room's temperature and humidity to drive your air conditioning controller.
From first reading to real automation
- First useSensor joins your network
Pair it with your Mi Home or Aqara hub following the app steps. Once connected, the app shows temperature and humidity for that room.
- Week 1Room patterns appear
Several days of readings show how the room changes between day and night. Use them to choose when the air conditioner should run.
- 30 daysAutomations run on real data
With automations set, the air conditioner responds to the room's actual conditions. Adjust thresholds based on what the readings show you.

Questions and answers
Yes, if you already run a Xiaomi or Aqara smart home hub. The sensor connects over ZigBee to that hub, and its readings appear in the Mi Home app next to your other devices.
The hub is the gateway. A compatible Xiaomi or Aqara hub is what the sensor reports to, so check that you own one before buying. Without a hub, there is nothing for the sensor to connect to.
It can work with an air conditioning controller to adjust temperature and humidity automatically. The sensor supplies the room readings and the controller acts on them.
Put it at seating or bed height, away from the AC vent, windows and heaters. Air blowing across the sensor or direct sun will skew the numbers, so the reading will not match the part of the room you use.
A wall thermostat reads one spot, usually where it is mounted. One sensor per room lets the automation respond to the room you actually use, and it runs in the app you already have instead of a second system.
