The EnviR display has some graphs for Night, Evening and Day consumptions. However, as far as I've read, the time intervals for those periods are 7-15, 15-23, 23-7. Surely these periods are not hardcoded and there are ways to configure them, right?!
Anyone can help?!
hardcoded and there is no way to configure them.
If you want anything more sophisticated you will need to join the ranks of those who upload the data from the EnviR. Basic requirement is a PC and a Current Cost Data Cable like http://www.amazon.co.uk/Current-Cost-Data-Cable-RJ45/dp/B002FVT3XW
There are a number of both free and commercial products available (See http://www.currentcost.com/software-downloads.html
) and opinion will vary on the "best". One of those that I continue to use (in lieu of looking at the EnviR) is Techtoniq Energy Station. It is a commercial product (UKP10) but you can evaluate it free for 30 days. I like it because it is "install and forget" it just keeps working.
Of course, depending on your level of PC expertise, your ultimate requirement and the amount of time you have available to jockey it, one of the others may be more suitable.
