This add-on door sensor works with the myQ Smart Garage Hub to monitor and control a second garage door opener. This version of the myQ door sensor is only compatible with the new myQ Smart Garage Hub by LiftMaster, Model 821LMB. This product replaces both 821LM-SENSOR and 821LMB-SENSOR and can be used as a replacement for either one. You will have the ability to monitor, open and close a second garage door opener with myQ Smart Garage Hub. Installation and programming are easy, just mount it to the inside top panel of the garage door and add to an existing myQ account through the MyQ app.
