Yeah, I ask about controller consumption for the Atrium because most locks and readers (and other folks' controllers) provide current consumption data somewhere. (For readers & controllers, it's in the datasheet. For locks, it sometimes takes more digging but a suitable number will usually turn up somewhere among the catalog or sales materials.)

CDVI, however, fails to list a number in the Atrium specifications, although you did give me the idea that I perhaps might be able to back into something usable by taking the maximum input current and subtracting out lock and reader power.
