A small, cheap Zigbee climate sensor that also reports air pressure, which most rivals in this price bracket leave out. Accuracy is quoted at ±0.3°C and ±3% RH, with around two years from a coin cell. The packaging says it needs an Aqara hub, but that only applies to the Aqara app: with a Zigbee coordinator running Zigbee2MQTT or ZHA it pairs directly. Aqara sensors can drop off the mesh if the parent router is poor, so put a mains-powered Zigbee router nearby.
What can Home Assistant control on the Aqara Temperature and Humidity Sensor T1?
| Control | Type | What it does |
|---|---|---|
| Temperature | Sensor (read-only) | Room temperature in °C |
| Humidity | Sensor (read-only) | Relative humidity in % |
| Pressure | Sensor (read-only) | Air pressure, handy for a simple weather trend |
| Battery | Sensor (read-only) | Battery level and voltage |
Supported by Zigbee2MQTT (model WSDCGQ12LM) and ZHA with no Aqara hub involved; readings arrive locally over your own Zigbee network. Zigbee2MQTT exposes calibration offsets and decimal precision, which is useful if one room reads a degree off.

Frequently asked questions
- Does the Aqara Temperature and Humidity Sensor T1 work with Home Assistant locally?
- Yes. The Aqara Temperature and Humidity Sensor T1 is controlled locally in Home Assistant through Zigbee2MQTT or ZHA, so it keeps working if your internet connection or the Aqara cloud goes down. Control and state updates stay on your own network.
- Which protocol does the Aqara Temperature and Humidity Sensor T1 use, and do I need a hub?
- The Aqara Temperature and Humidity Sensor T1 uses Zigbee. To pair it with Home Assistant you need a Zigbee coordinator (for example a SkyConnect/ZBT-1 or Sonoff dongle) attached to your Home Assistant host. Aqara's own hub is not required when you integrate through Zigbee2MQTT or ZHA.
