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 situation, to start irrigation of a certain period of time when soil moisture falls below a certain value.
Note: Check multiple moisture values during a certain period of time before and after irrigation, to ensure accurate soil moisture data when creating irrigation automation.
Installation
Recommendation: Use a suitable tool to dig a small hole in the soil and then insert the sensor.
- When installing the sensor, make sure the marked best line is flush with the soil surface. Diagram indicating the "Best Line" on the sensor probe.
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.
Setup with Third Reality Hub and SKILL
The Third Reality Hub (sold separately) allows you to control your device remotely via the Third Reality APP, making it a great option for smart home beginners or those without a system from major providers. Additionally, the Third Reality Cloud supports SKILL integration with Google Home or Amazon Alexa, enabling you to connect your device to these platforms. However, due to the potential for slow and unreliable Cloud-to-Cloud connections, it is recommended to use the Bridge solution 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 and release the hold. The blue blinking LED light indicates the sensor enters 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, you can enable the Third Reality SKILL in either the Alexa or Google Home app to enable Cloud-to-Cloud communication.

Setup with Smart Bridge MZ1
The Smart Bridge (sold separately) enables your Zigbee device to become Matter-compatible, allowing seamless integration with major Matter ecosystems like Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Home Assistant. By setting up your Zigbee smart soil moisture sensor with the Smart Bridge, it transforms into a Matter compatible smart color bulb, enabling local control through Matter. Third Reality also offers the 3R-Installer APP, which lets you configure Zigbee smart soil moisture sensor attributes such as default-on behavior and perform 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 and release the hold. The blue blinking LED light indicates the sensor enters 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, such as Google Home or Alexa.
- Optionally, you can 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 the need for 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 and release the hold. The blue blinking LED light indicates the sensor enters 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 turn the sensor on/off.
