This is a great project, and I'm considering getting myself a Fluksometer.
What's holding me back? Well, I already own a - closed-source :-( - Plugwise setup which is already answering many questions regarding our home power use (and additionally, running our boiler on off-peak tarrif). Monitoring water and global power usage could eventually convince me though :-)
One obvious question seems missing from the manual and from all webpages, or I looked over it: what is the power usage of the Fluksometer itself, in WiFi and Ethernet mode? As an owner of several OpenWRT routers, I am guessing in the order of 10-12W with WiFi on - is that correct?
Not that it's a deal-breaker; but it's just a relevant question to ask, I think :-)
