CHICAGO – Commonwealth Edison confirmed Thursday that three of its smart meters, which wirelessly relay power-use data between homes and the company, have been involved in “small fires” in the Chicago region.

ComEd said the problems stemmed not from the smart meters themselves but from how they were connected to homes and businesses.

The news, reported by Crain’s Chicago Business on Thursday, is the latest among recent concerns about the safety of the devices. Peco Energy Co. said this month that it suspended a smart-meter installation program after 15 of the 186,000 installed devices overheated.
