6.1 Malosiina o le Masini

The module can be powered using either a USB 5V power source or a DC 7-32V power supply connected to the input terminals.

1. Connect your chosen power source to the appropriate input terminals (USB 5V port or DC 7-32V screw terminals).
2. Once powered, the device will enter pairing mode, indicated by the network indicator light.

6.2 App Installation and Network Configuration

The Huacaoe Smart Relay Module operates with the Smart Life or Tuya Smart application.

1. Download the "Smart Life" or "Tuya Smart" app from your mobile device's app store (available for iOS and Android).
2. Resitala pe saini i lau teugatupe.
3. Ensure your mobile device's Bluetooth is enabled and it is connected to a 2.4GHz WiFi network. The module only supports 2.4GHz WiFi.
4. Open the app. The device should be automatically discovered. If not, tap the "+" icon to add a device and select "Auto Scan" or manually add a "Switch (Wi-Fi)".
5. Follow the on-screen prompts to enter your 2.4GHz WiFi network password.
6. The device will connect to your WiFi network. Once connected, the network indicator light will change status (e.g., solid blue).

Note: For environments without a continuous WiFi network, you can initially configure the device with 2.4G WiFi. After configuration, if the router settings are changed to block WiFi connectivity for the relay, you may still be able to use Bluetooth remote control if supported by the app and device.

7. Faiga Fa'atino

The module supports three primary operating modes, configurable independently for each of the four channels via the Smart Life/Tuya app.

7.1 Self-locking Latching Mode

In this mode, each relay acts as a standard on/off switch. Pressing the button (physical or in-app) toggles the relay's state.

• Turn on/off connected devices independently.
• The relay remains in its last state (on or off) until manually changed again.

7.2 Momentary Inching Mode

This mode is suitable for applications requiring a brief pulse of power, such as garage door openers or momentary button presses.

• When activated (via app or physical button), the relay will turn on for a set duration and then automatically turn off.
• The duration can be adjusted in the Smart Life/Tuya app, typically from 2 seconds to 1 minute.

7.3 Interlock Mode

Interlock mode ensures that only one relay can be active at a time. When one relay is turned on, all other relays in the interlock group are automatically turned off.

• Useful for applications where only one device should operate at a time, preventing conflicts.

8. Avatu Fa'apitoa

8.1 Fa'atulagaina ma Taimi

Automate your devices by setting schedules and timers within the Smart Life/Tuya app.

• Create single, repeat, circle, or countdown timers to automatically turn devices on or off at specified times.
• Timers can operate even if the network connection is temporarily unavailable.

Ata 8.1: Example of setting up a timing function in the Smart Life app to automate device operation.

8.2 Pulea leo

Ata 8.2: The module supports voice control through Amazon Alexa and Google Home, allowing hands-free operation.

8.3 Family Sharing

Share control of your smart devices with family members through the Smart Life/Tuya app.

• In the app, navigate to the device settings and select "Share Device" or "Family Management".
• Invite family members to control the module, enabling collaborative smart home management.

Ata 8.3: The family sharing function in the Smart Life app allows multiple users to control the smart relay module.

8.4 External Switch Pin Interface

The module includes an external switch pin interface, allowing for local control using momentary dry contacts. This is useful for integrating with microcontrollers or traditional wall switches.

• Connect external momentary switches to the provided harness and interface pins.
• These external inputs can trigger relays based on sensors or other digital inputs, providing a local override or additional control method.

9. Fa'apipi'i

The Huacaoe WiFi Smart Relay Switch Module is designed for easy installation, particularly with its DIN rail mountable ABS shell.

1. Fa'amauina: Secure the module to a DIN rail within an appropriate electrical enclosure.
2. Ulufale uaea: Connect the power supply (USB 5V or DC 7-32V) to the designated input terminals.
3. Uea Fausia: Connect the devices you wish to control to the relay output terminals (NO and COM). Remember that these are dry contacts, so the load requires its own power source. For example, to control a light, connect the light's power line through the NO and COM terminals of a relay.
4. External Switches (Optional): If using external switches, connect them to the external switch pin interface using the provided harness.
5. Siaki Saogalemu: Double-check all wiring connections before restoring power. Ensure no bare wires are exposed.
