There have been many reports of sudden plagues of random ONs and/or
OFFs after the installation of a "Smart" Meter by various electrical
utilities in various parts of the country. All of them appear to use
LonTalk (although identifying it by the ANSI standard number) to
communicate between meters and the Data Aggregator which usually
serves all of the meters on the same transformer. It appears to affect
X10-made modules and switches (but not those made by Smarthome).
