I have installed 3 Garadgets in my garage and all 3 work fine with the Garadget app. The problem is they now interfere with the original LiftMaster remote controls and the Homelink controls in our cars. It is rather inconvenient having to always use my phone to open and close the doors. I have disconnected the usb on one of the devices and both the remote and homelink are functioning properly again.
To resolve this please move Garadget(s) a bit further from the opener’s own antenna.
