Installation Guide

Before We Get Started

• Replace single pole switch. Not compatible with 3-way or 4-way switch.
• A neutral wire (white wire) is required.
• Only supports 2.4GHz WiFi networks.

*A 3 or 4-way switch is a light that is controlled by more than one switch.

1. Download the Meross app.

Download the Meross app from the following platforms:

• Download on the App Store
• Get it on Google Play
• Available at Amazon apps

2. Hardware installation.

Note: You can also refer to the instructions in the Meross app and follow them step by step.

1. Make sure your traditional switch is a single pole switch. This smart switch is not for 3-way or 4-way switches.
2. Place your smartphone near the traditional switch to ensure the location is covered by a strong Wi-Fi signal.
3. Get your tools ready and turn off the power at the circuit breaker that controls the switch. Double-check the power using a voltage detector.

   A diagram shows a circuit breaker panel with multiple switches. Some switches are in the 'ON' position, while one is clearly shown in the 'OFF' position, indicating the power should be turned off.

4. Remove the faceplate and pull out the traditional switch. Find the neutral wire (usually white) in your electrical box. This smart switch requires a neutral wire to work; otherwise, it won't work.

   A diagram illustrates the wiring connections for the smart switch. It shows the incoming power line (Lin), the outgoing load line (Lout), the neutral wire (Neutral), and the ground wire (Ground) connecting to the respective terminals on the smart switch and the electrical box. Wire nuts are depicted for secure connections.

5. Unscrew the wires and connect them according to the picture below.

   This diagram shows the wiring connections: Lin connects to the 'Lin' terminal, Lout connects to the 'Lout' terminal, Neutral connects to the 'N' terminal, and Ground connects to the ground terminal. The wires are shown coming from the electrical box and connecting to the smart switch.

6. Push the smart switch back into the box and turn the power on at the circuit breaker. If the switch works manually and the LED is flashing amber and green, then you are good to go for setting up. If not, please turn off the power at the circuit breaker and check the wiring.

For more detailed information, please refer to the Meross app.

3. Set up the device.

For Android users:

Open the Meross app and tap '+' on the top right. Just follow the instructions in the Meross app, and you will set it up in minutes.

For iOS users:

Please follow instructions below:

1. Please ensure that your iPhone or iPad is connecting to a 2.4GHz Wi-Fi. You may not be able to set it up otherwise.
2. Please make sure you are running iOS 13 or above. We recommend upgrading to iOS 14 for a better HomeKit user experience.
3. Use the Apple Home app instead of the Meross app to set it up. Just launch your Home app and tap "Add Accessory" or '+' on the top right and follow the instructions. It may take a few minutes, and then you'll be all set. The setup code is printed on the device and the user manual. Input the code on the label and wait. You should be able to set it up in a minute.

   Screenshots from the Apple Home app show the 'My Home' screen for adding accessories and the 'Add Accessory' screen, guiding the user to scan or input a HomeKit setup code. A placeholder for the setup code '1234 5678' is shown.

If you want to use HomeKit with an iOS device after setup on Android, just launch your Home app and scan or input the code printed on the device or user manual. No reset or extra configuration is needed.

After setup, if you wish to manage your MSS560 in the Meross app, please connect to your home Wi-Fi and launch your Meross app. Tap '+' on the top right. It will help you find devices on the same Wi-Fi network. Just tap 'add', and you'll be able to manage MSS560 in the Meross app. For example, upgrading firmware and binding to Amazon or Google voice assistants.

Note: 1. According to Apple HomeKit, the only way to set up a HomeKit accessory with iOS is via the Home app. If you don't want to set up with the Home app, you will have to use an Android device. 2. If you can't set up the device with the Home app, it might be due to an iOS cache issue with HomeKit devices. Please try the following:

• a. Reset the smart device and kill the Home app, then retry.
• b. Restart your iOS and retry. (This is important.)
• c. Ensure that your iOS is connecting to 2.4G of your home Wi-Fi.
• d. Have your iOS forget all other Wi-Fi in your home.

FAQ

At Meross, we strive to assure your satisfaction. We are always happy to help at support@meross.com.

1. What should I do when I can't turn the wall switch on/off manually?

Please check the Status LED. If it is off:

• Make sure that you restore power to the wall switch at the circuit breaker.
• Make sure the wall switch is wired correctly. Please consult with a qualified electrician.

2. What should I do when my Meross app is unable to control the added Wall Switch?

Please check the following:

• Check your home WiFi's Internet connection.
• Make sure your home WiFi's password hasn't been changed.
• Do not use a metal faceplate with the wall switch, as that will decrease the WiFi signal.
• Short press the reboot button to reboot the device. The device will reconnect automatically, with no extra configuration needed.

If all the above do not work, please factory reset MSS560 and try to add it again.

3. How do I pair my Meross devices with Amazon Alexa or Google Assistant?

Visit the Account -> Amazon Alexa or Google Assistant page within the Meross app for pairing instructions.

5. I can't pair my device with HomeKit anyhow.

Please make sure your iOS is connecting to the 2.4GHz of your home Wi-Fi and you are running iOS 13 or above. Restarting your iOS will help due to some system cache issues.
