5. Setup and Installation
5.1 Wiring Diagram (No Neutral Wire Required)
The SA-025 switch is designed for single live wire installations, meaning no neutral wire is required in your switch box. The anti-flicker module is essential for proper operation and must be connected to the light fixture.

Each channel control needs to be connected to the live line, and a "starter" (anti-flicker module) must be connected to the load. It is recommended to be installed by electrician professionals, and confirm that the line is in a power-off state before installation.
5.2 Physical Installation
- Turn off Power: Before starting, ensure the main power supply to the circuit is turned off at the circuit breaker to prevent electric shock.
- Remove Old Switch: Carefully remove your existing wall switch. Disconnect the wires, noting which wire is the live line (L In) and which goes to the load (L Out).
- Install Anti-Flicker Module: Connect the anti-flicker module to your light fixture. This module is crucial for the no-neutral-wire setup.
- Wire the Smart Switch: Connect the live input wire to the 'L In' terminal on the SA-025 switch. Connect the load wire(s) to the 'L Out' terminal(s) corresponding to each gang.
- Mount the Switch: Secure the SA-025 smart switch into the wall box using the provided screws. Attach the faceplate.
- Restore Power: Turn the main power supply back on at the circuit breaker.
5.3 App Pairing
To enable smart control features, you need to pair the switch with the eWeLink app.

- Download eWeLink APP: Search for "eWeLink" in your smartphone's app store (iOS or Android) and download it. Register or log in to your account.
- Power On: Ensure the SA-025 switch is powered on.
- Quick Pairing: Open the eWeLink app, tap the "+" icon, and select "Quick Pairing". Follow the on-screen prompts to complete the pairing process.
6. Operating Instructions
6.1 Manual Control
The SA-025 switch features a responsive push-button design. Simply press the button on the switch to manually turn the connected light(s) on or off.
This video demonstrates how to manually control the SA-025 switch and how to pair and use an RF remote control.
6.2 App Control
Once paired with the eWeLink app, you can control your lights remotely from anywhere with an internet connection.

The eWeLink app allows you to turn lights on/off, set schedules, and control groups of devices.
- Open the eWeLink app.
- Select your SA-025 switch from the device list.
- Tap the respective channel buttons (Channel 1, Channel 2, etc.) to turn lights on or off.
- Use the 'All ON' or 'All OFF' buttons for master control (if applicable).
6.3 RF Remote Control
The SA-025 switch has a built-in 433MHz RF chip, allowing it to be controlled by compatible RF remote controllers (sold separately or as part of a bundle).

The main switch can be paired with a portable sticker switch for flexible control.
- Enter Pairing Mode: Long press the button on the SA-025 switch that you wish to pair with the RF remote until you hear a "beep" sound.
- Pair Remote: While the switch is in pairing mode, press any button on your 433MHz RF remote. You will hear another "beep" sound, indicating successful pairing.
- Control: You can now use the paired button on the RF remote to turn the corresponding light on/off.
6.4 Smart Timing and Schedules
The eWeLink app allows you to set up schedules and timers for automated control of your lights.

Set multiple timers to control individual lights or groups of lights.
- In the eWeLink app, navigate to your SA-025 switch.
- Tap on the 'Schedule' or 'Timer' option.
- Set desired ON/OFF times for specific days or daily routines.
6.5 Voice Control (Alexa & Google Home)
Integrate your SA-025 switch with Amazon Alexa or Google Home for convenient voice control.

Control your lights hands-free using voice commands.
- Ensure your SA-025 switch is successfully paired with the eWeLink app.

Create automated routines by linking your SA-025 switch with other eWeLink compatible devices, such as door sensors or cameras.

Example: Lights turn on automatically when a door sensor detects entry.
- In the eWeLink app, go to the 'Scene' section.
- Create new scenes by setting conditions (e.g., door sensor opens) and actions (e.g., turn on SA-025 switch).
7. Maintenance
- Cleaning: Wipe the switch surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Firmware Updates: Periodically check the eWeLink app for available firmware updates to ensure optimal performance and security.
- Environmental Conditions: Ensure the switch is not exposed to extreme temperatures or humidity, which can affect its lifespan and functionality.
8. Troubleshooting
- Light Flickering: Ensure the anti-flicker module is correctly installed at the light fixture. This is crucial for no-neutral-wire setups.
- Switch Unresponsive: Check the power supply to the switch. Verify that the wiring is correct according to the diagram. If using app control, ensure your Wi-Fi network is active and the switch is connected.
- Cannot Pair with App: Ensure your Wi-Fi network is 2.4GHz (IEEE 802.11 b/g/n). Make sure the switch is in pairing mode (often indicated by a blinking LED). Try resetting the switch (refer to the eWeLink app for specific reset procedures if needed) and attempting pairing again.
- RF Remote Not Working: Ensure the RF remote is paired correctly with the switch. Repeat the RF pairing steps (Section 6.3). Check the remote's battery if applicable.
- Voice Control Issues: Confirm that your eWeLink account is correctly linked to Alexa or Google Home. Ensure the device name in eWeLink is recognized by your smart assistant. Try re-discovering devices in your smart assistant app.
9. User Tips
- Anti-Flicker Module: Always install the anti-flicker module, even if you don't immediately notice flickering. It helps stabilize the circuit for optimal performance in no-neutral-wire installations.
- RF Pairing: When pairing with an RF remote, ensure you long-press the specific gang button on the SA-025 switch you want to control before pressing the desired button on the RF remote. This ensures the correct channel is paired.
- App Scheduling: Take advantage of the eWeLink app's scheduling features to automate your lighting. This can save energy and enhance convenience, making your home appear occupied even when you're away.
- Device Naming: Use simple, distinct names for your switches in the eWeLink app for easier voice control (e.g., "Living Room Light" instead of "SA-025 Channel 1").
