5. Setup and Installation
The ATMS100133Z Smart Meter is designed for easy installation, particularly with its split-core current transformers that eliminate the need for cutting wires. It mounts on a standard 35mm DIN rail.
5.1 Mounting the Smart Meter
- Ensure the main power supply to the circuit you intend to monitor is completely turned off at the breaker.
- Locate a suitable position on a 35mm DIN rail within your electrical panel.
- Attach the smart meter to the DIN rail by aligning its back-mounted clips with the rail and pressing firmly until it clicks into place.
5.2 Wiring the Smart Meter and Current Transformers
The smart meter requires connection to the neutral and live wires of your three-phase system. The split-core current transformers (CTs) are used to measure current without direct contact with the main conductors.
- Power Connection: Connect the L1, L2, L3 (Live phases) and N (Neutral) wires from your main access switch to the corresponding terminals on the smart meter. The nominal voltage is 100-240V AC.
- Current Transformer (CT) Installation:
- For each phase (L1, L2, L3), open one split-core current transformer.
- Carefully clamp each CT around a single live wire (L1, L2, L3 respectively) that you wish to monitor. Ensure the CT is securely closed.
- Connect the red and black wires from each CT to the corresponding B1/R1, B2/R2, B3/R3 terminals on the smart meter. Ensure correct polarity if indicated on the CTs or meter.
- Double-check all connections for tightness and correctness before restoring power.
5.3 App Connection (Tuya Smart App)
- Download the 'Tuya Smart' app from your smartphone's app store (available for iOS and Android).
- Register or log in to your Tuya Smart account.
- Ensure your smartphone is connected to a 2.4GHz WiFi network. The smart meter only supports 2.4GHz WiFi.
- Restore power to the smart meter. The WiFi indicator on the meter should start blinking. If not, press and hold the 'Touch 5s to Connect' button on the meter for 5 seconds until it blinks rapidly.
- In the Tuya Smart app, tap '+' to add a new device.
- Follow the in-app instructions to discover and connect your smart meter. You may need to select 'Electrical' > 'Meter' or 'Energy Monitor'.
- Once connected, you can rename the device and assign it to a specific room or location.
6. Operation
Once installed and connected to the Tuya Smart App, your ATMS100133Z Smart Meter provides comprehensive energy monitoring and management features.
6.1 Real-Time Monitoring
Through the Tuya Smart App, you can monitor the following key metrics in real-time:
- Voltage (V) for each phase
- Current (A) for each phase
- Active Power (kW)
- Reactive Power (kVar)
- Power Factor
- Total Active Energy (kWh)
- Forward Energy (grid consumption)
- Reverse Energy (solar generation, if applicable)
6.2 Data Tracking and Analysis
The app records historical energy data, allowing you to:
- Track total active energy consumption over time.
- Analyze energy usage patterns to identify peak consumption periods.
- Monitor solar power contributions (reverse energy) for optimization.
- Detect anomalies in power usage that might indicate faulty appliances or inefficiencies.
6.3 Multi-User Sharing and Smart Alerts
- Device Sharing: Share access to your smart meter's data with family members or team members through the Tuya Smart App for collaborative energy management.

8.2 Device Not Connecting to App / WiFi Issues
- 2.4GHz WiFi: Confirm your router is broadcasting a 2.4GHz WiFi signal and your phone is connected to it during setup. The meter does not support 5GHz WiFi.
- Signal Strength: Ensure the smart meter is within range of your WiFi router.
- Reset WiFi: Press and hold the 'Touch 5s to Connect' button on the meter for 5 seconds until the WiFi indicator blinks rapidly to enter pairing mode.
- App Version: Make sure your Tuya Smart App is up to date.
8.3 Inaccurate Readings
- CT Installation: Ensure each split-core current transformer is correctly clamped around a single live wire and securely closed. Incorrect installation can lead to inaccurate readings.
- Wiring: Verify that all wiring connections (L1, L2, L3, N, and CT wires) are correct and tight.
- Calibration: While the meter is factory calibrated, significant discrepancies should be reported to support.
9. User Tips
