Does anyone know if it is possible to access the efergy elite meter that records A/C use from my inverter and is able to transmit information to my laptop or other devise? I see they are marketing a Online Energy Monitor Upgrader hub solo, but that appears to need a monthly subscription and presumably send information via a mobile connection. I desire some fancy graphs to monitor consumption!

Which Efergy unit was that?
This Maplin unit is supposed to be all free, keen to get one and then reverse engineer it myself. Might envolve some web site scraping to get data, or hacking the 433Mhz radio protocol...

10KW back boiler, old house, small scale solar heating. Rudimentary.

At this time the web based service is free, but I'm sure the small print allows that to change over time.

This site details the work someone did to decode the web API

One of their "see also:" footnotes also details what they discovered about which vendor is running the portal site and then links to their developer pages.

Why bother? - well, there is no planet B
