The Arduino solar meter
is a program that runs on an Arduino
This program started in 2009 when I got my first set of solar panels and wanted to log the production of the set. In the last 3 years, several additions and improvements were made. Because many people that also use this program ask for more documentation, I have created this project page.
The program can read information from various devices in your meter cabinet at home.
It will store this information on the onboard SD card and can send it to different websites to make nice graphics.
The most simple form of the Arduino solar meter
(V8.x) can read pulse information from 3 kWh meters via the S0 interface and send this information to 3 different systems on pvoutput.org
Additionally, (V9) a ferraris meter can be monitored in two directions to measure consumption and generation and a sensor can be connected to a gasmeter or a watermeter.
Version 10 now supports the Smart-Meter P1 port!
Discussions on the soft- and hardware can be found on the forum of Wijhebbenzon.nl
Version 11 adds the support for uploading of gas-usage to mindergas.nl
The minor releases (11.1 to 11.31 are stability updates and bugfixes.
Unfortunately, the memory in the Arduino is not large enough to hold all the options so a choice has to be made.
Look in the documentation
page to see how to connect the sensors and how the software works.
