three separate sources of data; house energy, garage energy and gas
consumption. I'll probably add external temperature at a later date.
I've started using an EnviR from Current Cost which can do all of that.
Quickly discovered that the EnviR's own logging is very limited. It's an
aggregate of two hours of readings. I need better granularity than that,
maybe log every 10 seconds.
The EnviR outputs a stream of data from a serial port every 6 seconds in
an xml format. Current Cost have a product called a NetSmart Bridge
which can send this information to a "Dashboard" page hosted by themselves.
The NSB costs about £30. You can guess where I am going with this. It
would seem a better solution to use an rPi to do the logging and
possibly server up the information locally on my home network. It will,
of course, have greater flexibility than the NSB.
Has anyone had any experience of doing this sort of thing?
