How many garage doors can be controlled using MyQ?
The LiftMaster MyQ Internet Gateway (828LM) can monitor and control up to 16 MyQ devices, while the LiftMaster MyQ Smart Garage Hub (821LM, 821LMB, 821LMC-SCM, MyQ-G0301, MyQ-G0401-ES) can monitor and control up to two (universal) garage doors each with a door sensor and up to 16 MyQ devices.
There is no prescribed limit to the number of LiftMaster gateways/hubs that can be added to an account.
Note: The MyQ Control Panel (888LM/889LM) requires an Internet Gateway to control MyQ devices, as it cannot control garage doors on its own.
