  Problem with IoT devices like LiftMster is that they rely on the same 'rolling code' technology (see 'Programming' https://www.liftmaster.com/CatalogResourcesV3/en-us/shared/files/tucmanuals/114A4503.pdf https://www.liftmaster.com/CatalogResourcesV3/en-us/shared/f...) to give the connected device (internet) access to open/close the door. This is long proven to be very insecure: http://www.wired.com/2015/08/hackers-tiny-device-unlocks-cars-opens-garages/ http://www.wired.com/2015/08/hackers-tiny-device-unlocks-car...
