5. Installation
5.1. Wiring Diagrams
Before proceeding with any wiring, ensure the power supply is turned OFF. The WSM16 modules come in versions requiring a neutral wire and versions that do not. Please identify your module type and follow the corresponding diagram carefully.
5.1.1. With Neutral Wire Version (1CH, 2CH, 3CH, 4CH)
Connect the Line (L) and Neutral (N) wires to the module's input terminals. Connect the load (light) to the output terminal (L1, L2, L3, L4) and the neutral wire. If connecting to a traditional switch, connect the switch output (S1, S2, S3, S4) to the corresponding input on the module.
5.1.2. No Neutral Wire Version (1CH, 2CH)
For modules without a neutral wire, a capacitor needs to be connected at L1 of all switch modules. Connect the Line (L) wire to the module's input terminal. Connect the load (light) to the output terminal (L1, L2) and the Line wire. If connecting to a traditional switch, connect the switch output (S1, S2) to the corresponding input on the module.
5.2. Physical Installation
The mini size of the WSM16 module allows for flexible installation. It can be easily installed within a standard switch installation box or directly on the lamp fixture.
5.3. APP Installation and Pairing
To enable smart control, you need to install the AVATTO or Smart Life app and pair your switch module.
- Download the APP: Scan the QR code provided in the physical user manual or search for "AVATTO" or "Smart Life" in the App Store (iOS) or Google Play Store (Android) to download the application.
- Register/Log In: Open the app and either register a new account using your mobile number or email address, or log in if you already have an account.
- Reset Key for Pairing: After the wiring of the switch module is complete, press the reset key on the module for about 10 seconds, or turn the traditional switch ON/OFF 5 times rapidly until the indicator light inside the module starts flashing quickly. This indicates it's in pairing mode.
- Add Device: Ensure your smartphone's Bluetooth is enabled. Open the app, and it should automatically detect the new device. Click "Add" and follow the on-screen instructions for pairing. Make sure your mobile device is close to the switch module (min. 50% Wi-Fi signal recommended).
- Network Connection: The connection process may take 10-120 seconds, depending on your network conditions. Once connected, you can control the device via your mobile phone.

6. Operating Instructions
6.1. APP Remote Control
Once successfully paired, you can control your lights from anywhere, anytime, using the AVATTO or Smart Life mobile application. The app allows you to turn lights ON/OFF, set schedules, and manage other smart features.
6.2. Dual Way Control
The WSM16 modules support dual-way control, allowing you to upgrade existing 2-way control switches without altering the original wiring design of your house. This means you can control a single light from two different physical switch locations, in addition to app control.
6.3. Group Control Function
For enhanced convenience, multiple switch modules in different rooms can be grouped together within the app. This allows you to control several lights or entire rooms simultaneously with a single command.
6.4. Manual Override
The switch module terminals are designed to allow for manual override. This means you can still use your traditional physical wall switch to turn the lights ON/OFF, even when the smart module is installed. The app control will synchronize with the manual switch state.
7. User Tips
- The App control is synchronized with the manual switch, ensuring consistent state across both control methods.
- For optimal configuration, keep your smartphone close to the switch module and ensure a minimum of 50% Wi-Fi signal strength.
- The device's compact size makes it ideal for installation within existing electrical boxes, helping maintain your interior aesthetics.
- Leverage the app's features such as timers, schedules, and the ability to trigger other smart switches for advanced home automation.
8. Troubleshooting
- Q: What should I do if I fail to configure the switch module?
- A: Please check the following:
- Ensure the device is powered on.
- Make sure your mobile device and the switch module are connected to the same 2.4 GHz Wi-Fi network.
- Verify that your internet connection is stable.
- Double-check that the Wi-Fi password entered in the App is correct.
- Confirm that the wiring connections are correct according to the diagrams.
- Q: What type of devices can be connected to the WiFi module?
- A: The module is suitable for controlling most household appliances, including lamps, laundry machines, and coffee makers, within the specified load limits.
- Q: What happens if the Wi-Fi connection goes off?
- A: You can still control the connected device using your traditional physical wall switch. When the Wi-Fi network becomes active again, the module will automatically reconnect.
- Q: What should I do if I change my Wi-Fi network or password?
- A: You will need to reconnect your Wi-Fi switch module to the new network by repeating the APP pairing process outlined in Section 5.3.
- Q: Does the polarity of the connection matter (e.g., can I apply Neutral to Line and Line to Neutral)?
- A: Yes, the polarity of the connection matters. Always connect the Line (L) wire to the terminal labeled 'L' and the Neutral (N) wire to the terminal labeled 'N' as indicated in the wiring diagrams to ensure proper and safe operation.
- Q: Is it possible to connect 3 light buttons together and manage them separately?
- A: Yes, if you have the 3-gang module (WSM16-W3), it allows connecting up to three separate light circuits. Each circuit can be controlled independently via the app or its connected physical switch.
9. Maintenance
- Clean the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Ensure that the installation area has proper ventilation, especially if the module is installed in an enclosed space, to prevent overheating.
- Regularly check for any loose wiring connections to ensure safe and reliable operation.
