I'm testing the Enymate product too .. .together with other similar products like www.wattcher.nl
Indeed in all those products the RF communication is not based on a standard although the Enymate is using bluetooth. An open standard interface based on Z-wave would be nice and may be under consideration
If you want to analyse your energy data you have to upload your history date to the Enymate website. It is not automated and manually activated .... at this moment no way to analyse your data on your own PC.
Also the way they do the analysis is not yet sophisticated but this will improve.
Will keep you informed,
