How It Works?

Below figure shows MSG100's main working principle. Simply wire it to your existing garage door opener and get its WiFi connected. Then you can enjoy above smart functions.

The installation is quite easy. Usually it only takes 15 minutes. 

In most cases, you only need to use the provided double adhesive tape.

*Note: This smart device won't impact your existing wall button and existing remote control, they are still available after installing MSG100.


Check Compatibility

MSG100 works with many traditional garage door openers, such as models from Chamberlain, LiftMaster, Hörmann and etc. Before you kindly back us. We need you to follow below steps for the compatibility confirmation.

1. Use pliers or electric wire to short the wall button terminals of your existing garage door opener. If garage door opens or closes, it works with MSG100. 

2. If above testing fails, but your garage door opener model is listed below or it has a learn button(normally the learn button's color is Purple/Yellow). It works with MSG100 but needs an extra accessory. Please kindly email us your garage door opener model and learn button color.

3. Please go to Compatibility Check for full bands/models check.
