Smart Grid WG and Electric Meter

The day's meetings in this conference room (Lighting has the other all day) kicked off with a two-hour meeting of the Smart Grid Working Group. David Holmberg led off with a review of where Smart Grid activities are today, then the working group reviewed Jim Butler's proposal "AC Electric Meter Device Interfaces" (JB-028-4). The direction for this proposal has not been established, whether it will result in a BACnet object or some generalized interface, though Jim is open for input on this.

He raised a question about the datatype to represent energy values; it was believed that Unsigned32 might be disfavored. But a poll of the working group failed to lead to a definitive direction -- most present ultimately voted "not qualified to respond."

It seems we have to look elsewhere for some answers.
