The reason to own one is not to read the temperature -- your phone will tell you that.
Aqara Temperature and Humidity Sensor T1 (Zigbee 3.0)
Editorial verdict
Grounded in published specifications
Summary verdict: The reason to own one is not to read the temperature -- your phone will tell you that. It is to trigger something: run the air conditioner when the bedroom passes 29 degrees, run the exhaust fan when bathroom humidity passes 70 percent. Because it is Zigbee and the logic sits on the hub, those triggers fire during an internet outage, which is exactly when an overheating room is least convenient.
Who should buy this
Anyone already running a Zigbee hub who wants humidity or temperature to drive automations.
Who should avoid this
Anyone without a hub, and anyone who only wants to see a number rather than act on it.
Key strengths
- Plus or minus 0.3 degrees C is genuinely accurate for the price
- Roughly two years on a single CR2032
- Automations run locally on the hub, unaffected by internet outages
Limitations
- Requires a Zigbee hub -- no standalone operation
- Reports on change rather than continuously, so graphs are stepped rather than smooth
- IP20 rules out bathrooms with direct splash exposure
