Home Monitoring (home made) – Overview

We have been working towards monitoring more and more items within the house to see the benefits of the solar array. Last time I posted an article about the meter reader which uses an Arduino and a light voltage converter to read the impulses from the import meter (a huge thanks goes out to Lars for his post here: http://www.lindnilsson.dk/lars/en/powermeter.php) but we wanted to expand on that and add in:

• Reading the export meter
• Reading the temperature of the hot water tank
• Reading when the hot water is heated by solar from the Wattson
• Aggregation of the data before uploading to PVOutput

(Because of the size of the code, this article has been split in to separate pages)

And finally the results of all work!
