THIRDREALITY Zigbee Temperature & Humidity Sensor 2-Pack, LCD Display and 20s Refresh for Smart Home

Keep reliable indoor climate data at your fingertips: these wireless sensors use Zigbee 3.0 to transmit temperature, humidity, and battery status to compatible hubs and smart home systems. Each unit refreshes readings every 20 seconds and displays current values on a clear LCD, while apps store historical records so you can review trends and trigger routines for HVAC, humidifiers, dehumidifiers, or fans.

How do these sensors connect to my smart home?

They pair with Zigbee 3.0 hubs and hub-enabled Echo devices to become part of your existing automation ecosystem. A Zigbee hub is required and sold separately; once joined they report regularly to the hub and any linked apps.

• Compatible with Echo (4th Gen), Echo Plus, Echo Studio, Eero 6/Pro 6, SmartThings, Hubitat, Home Assistant, Homey, Aeotec, and Third reality Hub.
• Works with assistants via a bridge: Apple HomeKit, Google Home, Alexa (via supported hubs/bridges).
• Supports OTA software updates through the compatible ecosystem.

What accuracy and refresh rate can I expect?

The sensor delivers frequent, reliable measurements suitable for everyday indoor monitoring. Temperature updates every 20 seconds with ±1°C accuracy within the -10°C to 50°C range, while humidity reads within ±2% across 0–95% RH.

• Temperature range: -10°C to 50°C (14°F–122°F), ±1°C accuracy.
• Humidity range: 0–95% RH, ±2% accuracy.
• Screen updates and wireless transmissions occur roughly every 20 seconds.

How can I use the sensor to automate my home?

Use the sensor as a condition in smart routines to respond automatically when climate thresholds are reached. Set alerts or actions through SmartThings, Home Assistant, Hubitat, or other compatible platforms to maintain comfort or protect belongings.

• Create alerts for high/low temperature or humidity levels through your app.
• Trigger HVAC, fans, humidifiers, or dehumidifiers based on sensor data.
• Log historic readings to spot trends and fine-tune schedules or energy use.

What about power and maintenance?

These sensors are engineered for low power consumption and straightforward upkeep. Two AAA batteries are included and typically provide around a year of operation under normal use, and the small enclosure makes placement easy.

• Powered by 2 AAA batteries (included); long-life, low-consumption design.
• Front-facing LCD shows temperature, humidity, and battery level for quick checks.
• Indoor use only; keep away from direct water exposure and extreme outdoor conditions.

Who is this for? Homeowners, renters, and hobbyists who want simple, accurate indoor climate monitoring and automation will appreciate this pack. It’s well suited for plant rooms, pet spaces, wine cabinets, nurseries, and general living areas when paired with a compatible Zigbee hub. If you need remote logging, alerting, and the ability to tie climate conditions into routines across SmartThings, Home Assistant, Alexa, or other Zigbee ecosystems, this EASY-to-install 2-pack gives you a reliable, budget-friendly way to add environmental intelligence to your home.
