Setup
1. Physical Installation
The ultra-mini size (41x41x22mm) of the MINI-W1 module allows for flexible installation. It can be placed behind an existing wall switch or directly inside a lamp fixture.

2. Wiring Diagrams
The MINI-W1 module supports three main wiring methods and is designed to be used with rocker switches. Ensure the main power is OFF before proceeding with any wiring.

- Method 1: Direct Connection to Light
Connect the module directly to the light fixture. This method uses L-out1 (Load Output), L-in (Line Input), N-in (Neutral Input), and N-out (Neutral Output).
- Method 2: Connects Light and Two-Way Rocker Switches
Integrate the module with a light and two rocker switches for two-way control. This method uses L-out1, L-in, N-in, N-out, S1, and S2 (Switch inputs).
- Method 3: Connects Light and a Single Rocker Switch
Connect the module with a light and a single rocker switch. This method uses L-out1, L-in, N-in, N-out, and S1.
Important: This module can only be used with rocker switches.
3. App Pairing
After physical installation and wiring, pair the device with the Smart Life or Tuya Smart app.
- Download the "Smart Life" or "Tuya Smart" app from your smartphone's app store (Google Play or Apple App Store).
- Register or log in to your account.
- Ensure your smartphone is connected to a 2.4 GHz Wi-Fi network.
- Power on the smart switch module.
- Open the app and tap "Add Device" or the "+" icon.
- Select the appropriate device type (e.g., "Switch" or "Lighting").
- Follow the in-app instructions to put the device into pairing mode (usually by pressing a button on the module for a few seconds until an indicator light blinks rapidly).
- Confirm the indicator light status in the app and proceed to add the device.
- Once added, you can rename the device for easier identification (e.g., "Bedroom Switch").

Operating Instructions
1. App Remote Control
Control your lights from anywhere using the Smart Life or Tuya Smart app on your smartphone or tablet. As long as your device and the smart switch module are connected to the internet, you have full control.

2. Voice Control
The module is compatible with Amazon Alexa, Google Home, and Yandex Alice. Connect your smart switch to these platforms to enable hands-free voice control.
- For Alexa: Enable the "Smart Life" or "Tuya Smart" skill in the Alexa app and link your account. Then, discover devices.
- For Google Home: Link the "Smart Life" or "Tuya Smart" service in the Google Home app.
Once linked, you can use commands like: "Alexa, turn on Bedroom Switch" or "Hey Google, turn off Living Room Light."

3. Timer, Schedule & Countdown
Set up custom schedules, timers, and countdowns within the app to automate your lighting. For example, schedule lights to turn on at sunset or off after a specific duration.
4. Dual Way Control
The module allows you to upgrade existing two-way control switches without complex rewiring. This means you can control a single light from two different physical switch locations, in addition to app and voice control.
5. Switch Type Options
The module supports different rocker switch behaviors:
- Rocker switch flip to change state: Each flip of the physical switch toggles the light's state.
- State synchronous: The physical switch state always matches the light's state.
- Self-reset switch: The physical switch returns to its original position after being pressed.
These options can typically be configured within the device settings in the Smart Life/Tuya Smart app.
6. Status Memory Function
Configure the module's behavior after a power outage. You can set it to:
- Turn ON
- Turn OFF
- Remember the last status before the power outage
This setting is usually found in the device's advanced settings within the app.
7. Interlock Function
For multi-channel modules (if applicable to your specific MINI-W1 variant), the interlock function ensures that only one channel can be ON at a time. When one channel is activated, any other active channel will automatically turn OFF.
8. Group Control
Combine multiple smart switches in different rooms into a single group within the app. This allows you to control all grouped devices simultaneously with a single command or tap.
9. Family Share Function
Share control of your smart switch with family members. The main account holder can grant limited or full access to other users, allowing everyone in the household to manage the smart lighting.

10. Linkage Function (Smart Scenes)
Create smart scenes by linking the MINI-W1 module with other smart devices, sensors, or appliances in your home. This enables automated actions based on specific conditions, such as:
- Sleeping Mode: Turn off all lights when you activate "Sleeping Mode."
- Working Mode: Adjust lighting to a preferred setting when you start "Working Mode."
- Back Home Mode: Turn on entryway lights when you arrive home.
Maintenance
- Keep the device clean and free from dust.
- Do not attempt to disassemble or repair the module yourself. Contact customer support if issues arise.
- Ensure the module is not exposed to water or excessive humidity.
- Regularly check for firmware updates through the Smart Life/Tuya Smart app to ensure optimal performance and security.
