Hi Art, I don't know of anything besides the MAP120 Parameter Editor software that = can talk to the optical port on those meters. And who knows how to get a co= py of that. I have a copy of the MAP120 user manual and also a brochure for= the meter - I can email those to you. But it won't get you any closer to = a useful utility than I got, which is fairly discouraged. Friendly regards, Bob ________________________________________ From: piclist-bounces@mit.edu on behalf of Art=20 Sent: Friday, November 25, 2016 8:57 PM To: Microcontroller Public Subject: [EE] Hucking Landis & Gyr Smart Power meter I have a Landis & Gyr E350 FOCUS AX-SD smart meter that I'd like to use to do some work on power factor correction-namely, how to inexpensively improve the power factor for LED light bulbs. They have outrageously poor power factors, if the utilities begin billing for reactive power..I think there might be a move back to incandescent lighting::> I got a neat little portable power meter called the Kill-a-Watt (model P4400) from my local library, and already found some big power suckers in the house! But it's pretty crude, especially for low power things like LED lights and it fails miserably at measuring standby power levels. But, I'd like to access the Landis & Gyr smart meter to get more detailed information from it and to continue research into power factor correction for these new fangled LED bulbs. I did obtain the manual for the smart meter, despite the manufacturers best efforts to deny me a copy::> It has an optical port that can be accessed without taking the cover off the meter, which makes it ideal for me. But, the manufacturer will not share any of the details on the software or hardware needed to extract the data I need from the optical port. The optical port is an "ANSI C12.18 type optical port". I did figure out that the optical interface/computer cable can be bought for reasonable $$. I also thought about building an interface to a computer sound card, which isn't a big deal technically, but I am not sure I could handle the software to extract the real time data from the voltage and current transformers output. But, sampling at 48K (or higher) would yield some nice high resolution V/A plots! Has anyone here hacked one of these smart meters or have any experience with them?? Email me off-list if you do not want to make a public response.
