Setup
1. Battery Installation
- Locate the battery compartment on the back of the sensor.
- Open the compartment cover.
- Insert two AAA batteries, ensuring correct polarity.
- Close the battery compartment cover securely.
2. Pairing with a Zigbee Hub
A Zigbee hub is required for this sensor to function and integrate with your smart home system. The hub is sold separately.
- Ensure your Zigbee hub is powered on and in pairing mode. Refer to your hub's manual for specific instructions on enabling pairing mode.
- On the sensor, press and hold the pairing button (usually located inside the battery compartment or on the side) for approximately 5 seconds until the LED indicator flashes. This indicates the sensor is in pairing mode.
- Once paired, the LED indicator will stop flashing or change color, depending on the sensor model. The sensor should appear in your Zigbee hub's application.
Compatible Zigbee Hubs: This sensor works with compatible Zigbee hubs or Echo devices with an integrated Zigbee hub, including:
- Echo (4th Generation), Echo Plus (1st and 2nd Generation), Echo Studio
- Eero 6, Eero Pro 6
- Home Assistant, SmartThings 2015/2018, Aeotec, Homey, Hubitat, Homey Bridge, Homey Pro
- THIRDREALITY Smart Bridge MZ1

3. Initial Placement
Place the sensor in your desired indoor location. The sensor is designed for indoor use only. Consider areas where temperature and humidity monitoring is critical, such as bedrooms, offices, wine cellars, or nurseries. The sensor includes 3M adhesive backing for easy mounting.
This image illustrates various indoor applications for the sensor, including monitoring conditions in a bedroom, an office environment, and a wine cellar.
Operating Instructions
1. Environmental Monitoring
The sensor continuously monitors temperature and humidity. Data is refreshed approximately every 5 seconds, providing near real-time readings. It features a high-quality Sensirion industrial-grade sensor for precise measurements.
- Temperature Accuracy: ±0.3 °C within a range of -15 °C to 50 °C.
- Humidity Accuracy: ±2% within a range of 0% to 100%.
2. Remote Monitoring and Historical Data
Once paired with a compatible Zigbee hub, you can monitor temperature and humidity remotely via your smart home application (e.g., SmartThings, Home Assistant, THIRDREALITY app). The THIRDREALITY app provides up to one month of historical data, while SmartThings and Home Assistant users can access more extensive historical data.
This image shows the sensor in a home environment with a pet, alongside a smartphone displaying the sensor's temperature and humidity data through a mobile application.
3. Smart Home Automation
Integrate the sensor with your smart home system to create automated routines based on temperature and humidity levels. Examples include:
- Setting alerts for extreme temperature conditions.
- Automating HVAC systems or fans to activate when a specific temperature threshold is reached.
- Activating a humidifier when humidity drops below a set percentage (e.g., 40%).
These routines can be managed through compatible smart home applications like SmartThings, Home Assistant, and Hubitat.
This illustration demonstrates how the sensor can be part of a smart home automation system, controlling devices like an air conditioner, smart blinds, and a humidifier to maintain optimal indoor climate.
4. Smart Assistant Support
When used with the Smart Bridge MZ1 (sold separately), the sensor can integrate with various smart assistants and home automation platforms, including Apple Home, Google Home, and Amazon Alexa, for convenient control and monitoring.
This diagram illustrates the sensor's compatibility with multiple smart assistant platforms, including Apple Home, Google Home, Amazon Alexa, and SmartThings, through the Smart Bridge MZ1.
Maintenance
1. Battery Replacement
The sensor uses two AAA batteries, which typically last for at least 2 years under normal usage conditions. When the battery level is low, your smart home application may provide an alert. Replace batteries as described in the 'Battery Installation' section.
2. Cleaning
To clean the sensor, gently wipe its exterior with a dry, soft cloth. Do not use liquid cleaners or immerse the device in water.
Troubleshooting
- Sensor Not Pairing: Ensure your Zigbee hub is in pairing mode. Check that the sensor batteries are correctly installed and have sufficient charge. Try resetting the sensor by removing and reinserting the batteries, then re-attempt pairing.
- Inaccurate Readings: Verify the sensor is placed in an appropriate indoor location, away from direct sunlight, drafts, or heat sources that could affect readings. Allow some time for the sensor to stabilize after initial placement or battery change.
- Connectivity Issues: Ensure the sensor is within range of your Zigbee hub or a Zigbee router. Obstacles like thick walls or large metal objects can interfere with the signal. Consider adding more Zigbee devices to strengthen your mesh network.
- Alexa App Only Shows Temperature: The Alexa application currently displays temperature readings but does not show humidity data for this sensor. This is a limitation of the Alexa app's integration.
- Battery Life Shorter Than Expected: Frequent reporting intervals or very cold environments can reduce battery life. Ensure the sensor is used within its specified operating temperature range.
