An SMA EV Charger 22 wallbox has recently been added to my network. This is of course primarily used to charge an electric car. <\/p>\n\n\n\n

Nevertheless, I was of course curious about which values could be read out and further processed there. <\/p>\n\n\n\n

The Node Red code presented below is my current status. This can be used to read out the most common consumption and producer data. This means you can access individual values of the power network as well as the connected car.<\/p>\n\n\n\n

Further information is summarized in this article.<\/p>\n\n\n\n

Safety instructions <\/span><\/h2>\r\n

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span>

<\/strong>To be able to install new nodes, NodeRed should of course already be installed on your RaspberryPi.
How to prepare a RaspberryPi and then install NodeRed on it is described in the following articles.<\/p>\n\n\n\n
