Just trying to figure out best way to pull out a reading from an electric meter from 2 weeks ago. Can this be accomplished thru ws/XbeeAttributeDataFull or ws/XbeeAttributeDataHistoryFull with parameters spec’d? I can’t find full description of parameters and their values, especially AttributeDateValue.

Or should I be looking at DataStreams to accomplish an historic value from 2 weeks prior?

Thanks.
