Controlling groups of electrical loads via multicast and/or unicast messages

A method comprising:

• determining whether a user interface event is an on event or an off event;
• when the user interface event is determined to be the on event or the off event and a number of multicast messages transmitted within a predefined period of time is within a predefined threshold, transmitting a digital message as a multicast message;
• and
• when the user interface event is determined to be an event other than the on event or the off event, transmitting the digital message as a unicast message.

At least one non-transitory computer-readable storage medium having computer-executable instructions stored thereon that, when executed by at least one control circuit, are configured to cause the at least one control circuit to:

• determine whether a user interface event is an on event or an off event;
• when the user interface event is determined to be the on event or the off event and a number of multicast messages transmitted within a predefined period of time is within a predefined threshold, transmit a digital message as a multicast message;
• and
• when the user interface event is determined to be an event other than the on event or the off event, transmit the digital message as a unicast message.
