HowTo: Node Red - Reading SMA Sunny Solar Inverter Data

In the articles Reading data from an SMA EV CHARGER 22 wallbox and Node Red - Read out SMA Sunny Home Manager data I had already described how to read out the respective measurement data.

Besides these SMA devices, there is also an SMA inverter in my network. Its measurement data can of course also be read out.

How you can read this data using Node Red, I have described in the following article.

Safety instructions

I know the following tips are always somehow annoying and seem unnecessary. But unfortunately, many people who knew "better" have already lost eyes, fingers or other things or injured themselves due to carelessness. In comparison, a data loss is almost not worth mentioning, 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 an injury or other trouble.

Helpful articles:
To be able to use NodeRed you should of course already have NodeRed installed on your Raspberry Pi.
How to prepare a Raspberry Pi for this and then install NodeRed on it is described in the following articles.

SMA Sunny Inverter Requirements

In order for the data of your SMA Sunny inverter to be read out, it should already be in operation and connected to your network. If you can already read out the data of your inverter with the SMA app, everything should be set up correctly.

Import Node Red code

In this section you will find the Node Red code you need. How you can import it into your NodeRed environment is described in the article NodeRed - Import and export node code described.

In order to use the node code linked below, you only need to enter the (local) access data for your inverter. You can find more information about this further down in the article.

You can find the NodeRed code in the Nerdiy Git repository at the following link:

View of the Node Red flow in the configuration interface.

View of the read out data in the dashboard view.

In order for the Flow to be able to read out the data from your inverter, you must now enter the login data. Open the marked node and enter the IP address, the user login data and the model of your inverter in the marked areas.

How you can find out the IP address of devices in your network I also wrote in the article

Have fun with the project

I hope everything worked as described for you. If not or you have questions or suggestions please let me know in the comments. I will then add this to the article if necessary.
Ideas for new projects are also always welcome 🙂 .

P.S. Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do it because I enjoy it, but if you think it's cool that I share the info about it with you, I'd appreciate a small donation to the coffee fund 🙂 .
