Methods and systems for access control involve dynamically controlling an access to firmware running a certified feature in an energy meter and a non-certified feature in the energy meter. The access can be based on a bifurcation between the certified feature and the non-certified feature running in the energy meter on one or more of a single microcontroller or a group of different microcontrollers.
