Ask YC: Wattvision vs. Black & Decker EM100B

Hi Sanj. Thanks for your message. Since Wattvision hasn't launched yet, I don't want to get in to too much detail, but in short, wattvision is faster, better, and cheaper. You'll hear more when we launch soon.

Thanks for your interest. Do hit up the team at info@wattvision if you want the details ;) -s

Hmm, I don't know. That black & decker device looks like it just uses photo detection or what not to read the reading from your electricity meter.

Other devices currently out use a clamp instead, this doesn't measure voltage and is therefore inaccurate.

If you like interesting power meters, check out the Wattson - http://www.treehugger.com/files/2006/07/wattson_monitor.php
