5. Installation (Setup)
Before proceeding with installation, ensure you have read and understood the safety information in Section 2. This module is designed to be installed inside a standard electrical junction box (e.g., Ø60 mm).
Wiring Diagram:
The module has terminals for Line (L), Neutral (N), Switch Input (L1), and Output (OUT). Refer to the diagram below for typical wiring configurations.
Figure 5.1: Back view of the module, highlighting the wiring terminals (L, N, L1, OUT).
- Turn Off Power: Locate the circuit breaker controlling the light or appliance you wish to automate and turn off the power. Verify that the power is off using a voltage tester.
- Access Junction Box: Open the electrical junction box where the traditional switch or appliance wiring is located.
- Connect Wires:
- Connect the Live (L) wire from your mains supply to the 'L' terminal on the module.
- Connect the Neutral (N) wire from your mains supply to the 'N' terminal on the module.
- Connect the Load (OUT) wire (going to your light or appliance) to the 'OUT' terminal on the module.
- If using a traditional wall switch, connect one terminal of the switch to the 'L1' terminal on the module and the other terminal of the switch to the 'L' terminal (Live). This allows for both smart and manual control.
- Secure Module: Carefully place the module inside the junction box, ensuring no wires are pinched.
- Restore Power: Close the junction box cover and turn the power back on at the circuit breaker.
After installation, the module is ready for app setup and pairing.
6. App Setup and Pairing
The Hom-io HOM-Mod-Switch module is compatible with the Hom-io app, which is based on the Smart Life platform. No separate hub is required.
Figure 6.1: The Hom-io app interface, demonstrating compatibility with Amazon Alexa and Google Home.
- Download the App: Download the "Hom-io" app from the Apple App Store (for iOS) or Google Play Store (for Android). Alternatively, you can use the "Smart Life" app.
- Register/Log In: Open the app and register for a new account or log in if you already have one.
- Add Device:
- Ensure your smartphone is connected to a 2.4 GHz Wi-Fi network. The module does not support 5 GHz Wi-Fi.
- In the app, tap the "+" icon (usually in the top right corner) to add a new device.
- Select "Electrical Switch" or "Switch (Wi-Fi)" from the device list.
- Enter Pairing Mode:
- With the power on, press and hold the traditional wall switch connected to the module for approximately 5-10 seconds until the indicator light on the module starts blinking rapidly. This indicates it's in pairing mode.
- Alternatively, if there's a physical button on the module, press and hold it.
- Confirm Blinking: In the app, confirm that the indicator light is blinking rapidly.
- Enter Wi-Fi Details: Enter your 2.4 GHz Wi-Fi network name and password.
- Connect: The app will begin searching for and connecting to the module. Once connected, you can rename the device and assign it to a room.
If pairing fails, ensure your Wi-Fi network is 2.4 GHz, the password is correct, and the module is within Wi-Fi range. You may need to reset the module by turning off and on the power three times (on-off-on-off-on) to force it into pairing mode.
7. Operation
7.1 Manual Control
You can continue to control the connected light or appliance using the traditional wall switch, even after the smart module is installed and paired. The module maintains synchronization between manual and app control.
7.2 App Control
Open the Hom-io (or Smart Life) app on your smartphone. Tap on the device name to access its control interface. From here, you can:
- Turn On/Off: Toggle the power of the connected device.
- Set Timers: Schedule specific times for the device to turn on or off (countdown, circular timer).
- Create Scenarios: Automate actions based on conditions like time of day, weather, or other smart devices.
- Step-by-Step Mode: Manually force an impulsive mode via the app for specific applications (e.g., gate openers).
- Power-Off Memory: Configure the device's state after a power outage (e.g., remain off, turn on, or restore last state).

- For Google Home: Go to "Works with Google" and search for "Smart Life" or "Hom-io". Link the service.
- Link Account: You will be prompted to log in with your Hom-io/Smart Life app credentials.
- Discover Devices: Once linked, ask your voice assistant to discover devices (e.g., "Alexa, discover my devices" or "Hey Google, sync my devices").
- Voice Commands: You can now control your module using voice commands, such as:
- "Alexa, turn on [Device Name]"
- "Hey Google, turn off [Device Name]"
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Module not pairing with app. | Incorrect Wi-Fi band (5GHz), wrong password, module not in pairing mode, weak signal. | Ensure 2.4 GHz Wi-Fi. Check password. Reset module (power cycle 3 times) to enter pairing mode. Move router closer or use a Wi-Fi extender. |
| Device not responding to app/voice commands. | No internet connection, module offline, voice assistant not linked. | Check home internet connection. Verify module status in app. Relink Smart Life/Hom-io skill/service in Alexa/Google Home app. |
| Traditional switch not working. | Incorrect wiring of the L1 terminal. | Review Section 5 (Installation) and check wiring connections, especially for the L1 terminal. Ensure power is off before checking wiring. |
| Module frequently disconnects. | Weak Wi-Fi signal, network interference, router issues. | Improve Wi-Fi signal strength. Reduce interference from other devices. Restart your Wi-Fi router. |
