3. Setup and Installation

Follow these steps to set up your SM4-WLTE controller:

1. Prepare SIM Card: Ensure your Micro SIM card (3V) has no PIN code enabled. Insert it into a mobile phone first to disable the PIN, if necessary.
2. Install SIM Card: Locate the SIM card slot on the controller. Gently insert the prepared Micro SIM card until it clicks into place. Ensure correct orientation as indicated on the device.
3. Attach Antenna: Screw the external SMA antenna onto the antenna interface on the controller. Ensure it is securely fastened for optimal signal reception.
4. Connect Power: Connect the DC12V power adapter to the controller's power input port. Plug the adapter into a standard 110-220V AC outlet. The device will power on automatically.

6. Configure Application:
   • Enable the APP and register an account using your email address.
   • Add your device by scanning the UID QR code on the device or by manually entering the UID and default password (usually 1234).
   • Ensure your mobile phone has internet access for APP control.
7. Network Status Check: Observe the 'SIG' LED indicator on the controller. It should flash 4 times quickly, then turn into a slow flash (every 2 seconds) after 1-3 minutes, indicating successful network connection. If it continues to flash quickly or stays off, check SIM card installation and antenna connection.

4. Operating Instructions

4.1. APP Control Interface

The mobile application provides an intuitive interface for controlling the SM4-WLTE module.

• Relay Control: Each of the 4 channels can be controlled individually. Tap 'ON' or 'OFF' to toggle the relay state. You can also set a 'Jog' time for momentary activation.
• All ON/OFF: Buttons are available to turn all relays on or off simultaneously.
• Refresh Status: Update the current status of all relays and inputs.
• Device Center: Manage device settings, modify passwords, and access advanced functions.

4.2. Timing Settings

The app allows you to set up to 24 groups of timing tasks for automated control.

• Navigate to 'Timing Settings' in the app menu.
• Add a new timing task, select the channel, set the desired time, and choose the timing cycle (daily or single day).

4.3. Input Control

The module supports 4 input interfaces (Input 1-4) for connecting passive switches or micro switches. These inputs can trigger actions or provide status feedback.

• In the app, go to 'Input Control'.
• You can configure each input to 'Connect' (trigger when connected to GND) or 'Disconnect' (trigger when disconnected from GND).

4.4. Temperature and Humidity Control

If equipped with sensors, the module can monitor temperature and humidity and trigger actions based on set thresholds.

• Temperature Settings: Set up to 12 sets of temperature control rules. Define a temperature range, and assign actions (e.g., turn on a fan if too hot, turn on a heater if too cold).
• Humidity Settings: Set up to 4 sets of humidity control rules. Define a humidity range and assign actions.

4.5. SMS Control

The SM4-WLTE can also be controlled via SMS commands. Anyone with the correct SMS command and password can send a text message to control the 4 relay outputs. Refer to the detailed SMS command list in the full product documentation for specific commands.

5. Wiring Diagrams

The following diagrams illustrate common wiring configurations for various applications. Professional installation is recommended for high-power or complex wiring. Always ensure power is disconnected before wiring.

5.1. Basic Wiring Examples

• 1. Low Power Lamp or Home Appliance: Connect a low-power AC device directly to a relay output.
• 2. DC Motor or Equipment Application: Connect a DC motor or equipment to a relay output.
• 3. High-Power AC Motor / Equipment Application: For high-power AC loads, an external AC contactor is required. The relay controls the contactor, which in turn controls the high-power equipment.
• 4. Trigger to Control Electronic Lock: Use an input to trigger a relay that controls an electronic lock.
