  • Important Information: Only for single pole installation. Neutral wire(in white color normally) is required. Needs a 2.4GHz Wi-Fi connection. Fits for 1/2/3/4 gang standard size Decora/GFCI wallplate. 15 minutes quick installation.
  • Multiple Control Methods: Control the switch through your smartphone, your voice, or the hardware button. Turn the switch on/off from anywhere with your smartphone(internet accessed) using the eHomeLife app or Home app, no hub is needed. Enjoy the hands-free convenience of controlling the switch in your home with your voice. Compatible with Apple HomeKit, Amazon Alexa, and Hey Google.
  • Local and Off-line Control: When the smart device and the phone are connected to the same Wi-Fi, the mode of local control will be activated and your operations will have a millisecond-level response. Even if the router is disconnected from the internet, you can still control the smart device through the Refoss app.
  • Scene and Routine: Group multiple Refoss devices to be a scene and control it with one tap. Link your Refoss account to Alexa or Google and activate the scene with voice. A routine enables you to run a smart device with a schedule that includes auto on/off or countdown off. Support sunrise and sunset setting. An added benefit of saving energy. A routine can be set for the scene to auto on/off. When the mode of off-line control is active, you can still run scenes and the saved routines won’t be affected.
  • Safety: Local control protects your privacy because the app doesn’t transmit operation commands to a cloud server. The housing of the switch is made from PC-ABS which has excellent heat resistance, dimensional stability, and impact resistance. Circuit design protects the switch against electricity overload.
  • Support: If you have any questions about switch type, installation, connection, or other aspects, please feel free to contact us, we will provide solutions until you feel satisfied.

1. What should I do when my Refoss app cannot control the added wall switch?

You can troubleshoot in the following ways:
Check the Internet connection of the home Wi-Fi.
Make sure your home Wi-Fi password has not been changed.
Do not use a metal faceplate on the wall switch, as that will reduce the Wi-Fi signal.
Restart the switch by pressing the restart button.
If all other methods fail, press and hold the power button for 5 seconds to restore factory settings, and then try to add again.
