- Press and hold the reset button for 5 seconds until the LED light turns red. Release the reset button, and the LED will start blinking blue, indicating it has entered Zigbee pairing mode.
- Follow the instructions of your smart home hub or smart speaker with a built-in Zigbee hub to pair the sensor in the corresponding app.
Installation
Recommendation: Use a suitable tool to dig a small hole in the soil and then insert the sensor.
- When installing the sensor, ensure the marked line (referred to as "Best Line") is flush with the soil surface for accurate readings. [Diagram: Sensor probe showing the 'Best Line' indicator]
- Friction can damage the sensor and affect its accuracy. It is not recommended to insert the sensor directly into hard soil, which may damage the sensor.
- The sensor is designed to measure soil moisture ONLY.
How to Use
Set up your smart soil moisture sensor. When inserting the sensor into the soil to be measured, align the sensor's marking line with the soil surface to ensure measurement accuracy.
Create an automation or water the plant manually based on your observation of specific plant and soil situations. This allows for irrigation to start after a certain period of time when soil moisture falls below a specified value.
Note: Check multiple moisture values during a certain period before and after irrigation to ensure accurate soil moisture data when creating irrigation automation.
Setup with Third Reality Hub and SKILL
The Third Reality Hub (sold separately) allows remote control of your device via the Third Reality APP, making it suitable for smart home beginners or users without systems from major providers. The Third Reality Cloud also supports SKILL integration with Google Home or Amazon Alexa, enabling connection to these platforms. For potentially slow and unreliable Cloud-to-Cloud connections, using a Bridge solution is recommended if Google Home or Alexa is your primary smart home platform.
- Ensure your hub is properly set up with the Third Reality App.
- Open the battery cover, install the battery, press and hold the reset button for 5 seconds, then release it. The blue blinking LED light indicates the sensor has entered Zigbee pairing mode.
- Open the Third Reality APP, press the "+" icon next to the hub, and select "Quick Pair."
- The sensor will pair with your hub and appear in the Third Reality APP.
- Optionally, enable the Third Reality SKILL in either the Alexa or Google Home app for Cloud-to-Cloud communication.
Setup with Smart Bridge MZ1
The Smart Bridge (sold separately) makes your Zigbee device Matter-compatible, enabling seamless integration with major Matter ecosystems like Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Home Assistant. Setting up your Zigbee smart soil moisture sensor with the Smart Bridge transforms it into a Matter-compatible device, allowing local control through Matter. Third Reality also offers the 3R-Installer APP for configuring Zigbee smart soil moisture sensor attributes and performing firmware updates.
- Ensure your bridge is already set up within your smart home system.
- Open the battery cover, install the battery, press and hold the reset button for 5 seconds, then release it. The blue blinking LED light indicates the sensor has entered Zigbee pairing mode.
- Press the pinhole button on the bridge to activate Zigbee pairing mode. The Zigbee blue LED should start blinking.
- The sensor will pair with the bridge, and a new device will appear in your smart home app (e.g., Google Home or Alexa).
- Optionally, install the 3R-Installer APP and use the multi-admin feature in your smart home app to share permissions with the 3R-Installer APP.
Setup with Compatible Third-Party Zigbee Hubs
Third Reality supports integration with various open Zigbee platforms, including Amazon Echo with built-in Zigbee, Samsung SmartThings, Home Assistant (with ZHA or Z2M), Homey, and Hubitat. If you own any of these devices, you can pair the smart soil moisture sensor directly without needing an additional bridge or hub.
- Ensure your Zigbee Hub is already set up within your smart home system.
- Open the battery cover, install the battery, press and hold the reset button for 5 seconds, then release it. The blue blinking LED light indicates the sensor has entered Zigbee pairing mode.
- Open your smart home app and follow the on-screen instructions to begin the Zigbee pairing process.
- The sensor will flash and then turn warm white, indicating it has successfully paired with the Zigbee hub.
- You can now use your smart home app to control the sensor (e.g., turn it on/off).
