There are only 6 java classes, 1 properties file and the flow (XML) file making up the Mule application. Some of them can be better written and should be unit tested, but they work and do the job :-)) ConsumptionData.java DefaultReadingData.java HotWaterData.java ConsumptionInputDataTransformer.java ExtraDataOutputTransformer.java HotWaterInputDataTransformer.java pvoutputaggregator.properties pvoutputaggregator.mflow Next Part Part …
Aggregation of the data before uploading to PVOutput Why do we need to aggregate the data? The data collected by the meter reading Arduino will be sent to PVOutput on the addstatus service using the standard parameters. The hot water Arduino will be sending the data on the extended parameters …
Reading when the hot water is heated by solar from the Wattson plug Since the Wattson plug and the hot water tank are in close proximity, we can reuse the Arduino that reads the temperate to determine when the Wattson plug is on and heating the water. Another light voltage …
Reading the temperature of the hot water tank This one is not as easy as the export meter as the meter cupboard and the hot water tank are not in the same area as one another, so we had to purchase another Arduino. This time instead of a wifi shield …
Reading the export meter Reading the export meter is relatively easy as the Arduino in the meter cupboard can be extended to have another light voltage converter to read the export meter. So we purchased another part from CPC (for those interested in replicating this, you can use one of …
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 …
Before we had the kitchen upgraded, the dining room had the brightest lights (eight, 40 watt standard bulbs) and it was thee room to be in during the winter because of the light. That all changed when we had a new kitchen fitted back in 2001. Back then the modern(ish) …
When I was deciding which solar company to go with, I found out that some of the inverters had inbuilt internet access and others could have data logging added. The system I have (Sunny Boy 3800 and bluetooth piggyback with Sunny Beam) allows me to collect csv files of the …
I had my solar panels switched on today! I’ve wanted solar panels or a wind turbine for over 3 years now and finally have my own. The process started in July this year when I decided to find out the true cost of installation. I contacted a local building firm …
