I'm interested in getting an outlet that monitors power usage. In reviewing outlets on the HomeKit items available thread, there were some options but some seem to be announced but never released or are out of stock when I check. My main purpose for the outlet is not so much the ability to turn on and off a device but to monitor the power usage. Ideally the app would record peak draws and have some sort of charting function. Even better would be if the app would allow for downloading the data for analysis in a spreadsheet (I can dream can't I?). Bottom line, what do you recommend for an outlet for monitoring and tracking power usage?
