Abstract
A ballast control unit for controlling at least one light output of at least one dimmable ballast is disclosed, in which the dimmable ballast powers one or more light sources via the light output(s). The ballast control unit includes a wireless interface provisioned to receive messages from a mesh network, and to retransmit the received messages not destined for the ballast control unit. The ballast control unit further includes a control module provisioned to control the dimmable ballast(s) and the light output(s) according to commands in the received messages destined for the ballast control unit, where the commands correspond to the dimmable ballast(s) and/or the light output(s).
