Monitor Soil Moisture and Temperature Through Your Zigbee Smart Home
What is the Tuya GXM-01?
The Tuya GXM-01 is a Zigbee 3.0 smart soil sensor designed to measure soil moisture and soil temperature around potted plants, gardens, greenhouses and other growing areas. It sends its readings to a compatible Zigbee gateway or coordinator, allowing users to view plant conditions, receive notifications and create watering automations.
The Tuya GXM-01 can be connected through a compatible Tuya gateway for use with the Smart Life app. The model has also been integrated with Home Assistant through ZHA and Zigbee2MQTT, where it can expose soil moisture, temperature and battery information. A compatible Zigbee hub or coordinator is required because the sensor does not connect directly to Wi-Fi.
Key Takeaways
- Main benefit: Monitor soil moisture and temperature without manual testing.
- Primary use: Plant-care alerts and moisture-based irrigation automations.
- Connectivity: Zigbee 3.0.
- Compatibility: Smart Life, compatible Tuya gateways, Home Assistant ZHA and Zigbee2MQTT.
- Measurement ranges: 0%–100% soil moisture and -20°C–60°C temperature.
- Protection: Common GXM-01 versions are advertised with an IP67 enclosure.
- Hub requirement: A compatible Zigbee hub, gateway or coordinator is required.
Key Benefits
- Know when plants need water using real-time soil moisture readings.
- Track root-zone conditions with integrated soil temperature monitoring.
- Create smart watering alerts through Smart Life or Home Assistant.
- Use local Zigbee automations with ZHA or Zigbee2MQTT.
- Place the sensor outdoors where appropriate for the verified IP67 version.
Make Plant Care More Predictable
Watering plants according to a fixed schedule does not always produce healthy results. Different pots, soil mixtures, plant varieties and weather conditions can cause one plant to dry much faster than another.
The Tuya GXM-01 Zigbee Soil Sensor helps solve this problem by monitoring conditions directly in the soil. Once the probe is inserted at the correct depth, the sensor measures soil moisture and temperature before sending that information to a connected Zigbee system.
Users can view current readings inside Smart Life when the sensor is connected through a supported Tuya gateway. The app can retain recent historical data, helping users observe how quickly the soil dries after watering. The available manual states that readings begin approximately one to two minutes after installation and that Smart Life retains the most recent seven days of data.
Home Assistant users can also pair compatible GXM-01 variants through ZHA or Zigbee2MQTT. A documented version identifies itself as TS0601_soil with manufacturer identifier _TZE200_myd45weu, although identifiers can differ between hardware batches. Through Zigbee2MQTT, the documented device exposes soil moisture, temperature, battery state, battery percentage and temperature-unit controls.
The Tuya GXM-01 is designed for plant owners, greenhouse users and smart-home enthusiasts who already operate a Zigbee network. It is especially useful for creating low-moisture alerts or automations that water plants according to measured conditions rather than a rigid calendar.
Why Choose the Tuya GXM-01?
Monitor Soil Moisture from 0% to 100%
The Tuya GXM-01 reports soil moisture across a stated range of 0% to 100%. This allows users to monitor changes after watering and identify when soil is beginning to dry.
Moisture percentages should be treated as comparative plant-care data rather than a universal watering rule. The ideal threshold varies according to the plant species, potting mixture, drainage and probe position.
Measure Soil Temperature
The sensor also reports soil temperature across a stated range of -20°C to 60°C, with a published accuracy claim of ±1°C for reviewed versions. Soil temperature data can help users monitor growing conditions in greenhouses, garden beds, conservatories and outdoor containers.
Connect Through Zigbee 3.0
Zigbee connectivity allows the sensor to operate as a low-power end device inside a compatible Zigbee network. Unlike a standalone Wi-Fi sensor, the Tuya GXM-01 requires a gateway or coordinator to transmit readings to a mobile app or smart-home platform.
Use the Smart Life App
When connected through a compatible Tuya Zigbee gateway, the Tuya GXM-01 can be added to the Smart Life app. The available instructions describe installing Smart Life, placing the sensor into pairing mode and adding it through the app’s device setup process.
Smart Life may be used to:
- View soil moisture
- Check soil temperature
- Review recent sensor history
- Create low-moisture notifications
- Build automations with compatible Tuya devices
Integrate with Home Assistant
Compatible GXM-01 variants can operate through both major Home Assistant Zigbee options:
- Zigbee Home Automation, or ZHA
- Zigbee2MQTT
The reviewed GXM-01 version was recognised in ZHA through a Tuya soil-sensor quirk and exposed moisture, temperature and battery data. Zigbee2MQTT exposed similar readings along with temperature-unit and temperature-calibration controls.
Create Moisture-Based Watering Automations
The sensor can be combined with a compatible smart plug, irrigation valve or water pump.
Possible routines include:
- Notify your phone when moisture falls below a selected threshold.
- Start irrigation after the soil remains dry for a specified period.
- Stop watering after a maximum runtime.
- Prevent scheduled irrigation when the soil is already wet.
- Monitor different moisture thresholds for different plants.
Always include a maximum runtime or shutoff condition when controlling a water pump automatically.
Use in Gardens and Growing Areas
The GXM-01 has been marketed for potted plants, gardens, farms, orchards and greenhouses. Reviewed units were specified with an IP67 enclosure designed to resist dust and temporary water exposure. IP67 does not mean the sensor should remain permanently submerged.
