It’s been an exciting month here at Netsecure Automation. We have just completed Australia’s first true smart home solar integration with a Tesla electric car. Our client recently took delivery of a lovely Tesla Model S and asked us to provide some visibility of the car. We love a challenge so we embarked upon expanding our smart home app to provide real time information on both the car and the solar status. Our brief was then to ensure that his car charges when his 3 phase solar array is producing more than the current electricity demands of the house.
With the use of the Tesla API and our smart home system which out of the box supports all Tesla electric cars. We are then able to read the current data in real time and feed this information into the customers app for a visual representation of what’s currently occurring. The data includes information such as charging state, door state, time required to full charge and the battery history. Tesla provide a fantastic API that allows us to take full advantage of the it’s features and provide some truly amazing data. We can even report in real time as a mobile alert if the car is speeding !
Integrating the Solar
Once we were able to read in the car data we then turned our attention to the Solar system. Again, out of the box our smart home package has integration with Solar Edge who provide a range of inverters for the solar market. With the solar data fed into our smart home controller we can begin to make energy conscious decisions about how and when we charge the Tesla.
One of our benefits is the endless flexibility we have when it comes to make decisions through the use of smart home ‘rules’. This allows the system to evaluate data from thousands of sources to provide true automation!
As you can see, the Solar stats are fed into our controller and provide current ‘consumption’ within the home, our current export to the grid amount, our production amount and many more. This data then rolls up into an aggregate which we can display, if need be, into graphs or even send this information via smart alerts to any mobile device or announce them via Alexa! very powerful.
The system now will detect if the car is at home, plugged in and if the solar is producing more than the home is consuming. (with a check to ensure we are above 4kW in terms of excess output). If this checks out as being true, the car will begin to charge. Very neat!
If you’re looking at solar integration with a Tesla or building a smart home in Sydney, please give us a call. We have some exciting and reliable solutions to ensure cost effective methods to charging your vehicle.
