Watts Clever - STC-4004 now discontinued
The above models of wireless energy monitors have introduced some differences to the original STC-4002 and CLASSIC models, In particular the XML like file output has changed and the frequency in which is delivered from the STC-4004\ENVI is significantly different. In my personal view these changes have not added any significant value to the product and in some cases are a real pain. In my view the earlier STC-4002\CLASSIC is my favourite device and has been more reliable when comparing both monitors side by side.
In this document I will start to detail the differences that will assist customers who have purchased the STC-4004 \ ENVI.
