FAQ
At Meross we strive to assure your satisfaction. We are happy to assist at support@meross.com.
- What should I do when I can’t tum the wall switch on/off manually?
Please check the LEDs. If all the LEDs are off:
• Make sure that you restore power to the wall switch at the circuit breaker.
• Make sure the wall switch is wired correctly.
• Make sure your master switch has been installed in an electrical box with both live and neutral wire. If you are not sure, switch the installation position of your master and • add-on switch and try again. - What should I do when my Meross app is unable to control the added wall switch?
You can troubleshoot the following:
• Check your home Wi-Fi’s internet connection.
• Make sure that your home Wi-Fi password hasn’t been changed.
• Do not use a metal faceplate with the Wall Switch as that will decrease the Wi-Fi signal.
• Reboot your switch by pressing the restart button.
• If all else fails, factory reset switch by pressing the power button for Ss and try to add it again. - How do I pair my Meross devices with Amazon Alexa or Google Assistant?
Visit Account->Amazon Alexa or Google Assistant page within Meross app for pairing instructions. - Only one of the two electrical boxes has a neutral wire, will it work?
Yes, if the electrical box with neutral wire is exactly the one with a live wire. Then install the master switch(MSS570MA) in it will work. Please be noted that neutral wire and live wire must be in the same electrical box. - My two traveler wires are in the same color. I can’t tell Traveler-1 from Traveler-2.
You can finish add-on switch installation first and ignore the color guidance of traveler wires temporarily. Don’t worry, it won’t cause any short circuit. And then power on the smart switch at the circuit breaker to see whether your switches work properly or not. If not, power off your circuit breaker again. Switching the wiring position of Tl and T2 on add-on switch will solve the problem. - My switches are not working. All brightness LEDs are blinking and I can’t tum on and off my light.
This means you connected Traveler-1 from the master switch to
Traveler-2 of your add-on switch. Switching the wiring position of Tl and T2 on the add-on switch will solve the problem. - My switch keeps dropping and can not connect to the Wi-Fi.
Make sure your master switch is covered with strong Wi-Fi. If not, we suggest you use a Wi-Fi range extender, MRE120 for example, to get your switch covered. Also, make sure your Wi-Fi password hasn’t been changed. If still not working, please press the restart button to reboot your switch. - Why my iOS will require me to use the Home app when setting it up?
This is required by Apple iOS. If you want to manage your device in the Meross app, please launch your Meross app after the setup and tap+ on the top right. Meross app will find devices in the same Wi-Fi network. - 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 having iOS 13 or above. Restart your iOS will help due to some system cache issue.
