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.

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

In the following article I have described how you can read this data using Node Red.

Safety instructions

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.

Helpful articles:
So that you can use NodeRed, NodeRed should of course already be 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.

In the following lists you will find all the parts you need to implement this article.

SMA Sunny Inverter Requirements

So that the data of your SMA Sunny inverter can be read, it should already be in operation and connected to your network. If you can already read out the data from 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 this into your NodeRed environment is in the article NodeRed - import and export node code described.

To be able to use the node code linked below, all you have to do is enter the (local) access data for your inverter. You can find 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 the data from your inverter, you now have to enter the login data. To do this, open the marked node and enter the IP address, the user login data and the model of your inverter in the marked areas.

I also have in the article how you can find out the IP address of devices in your network

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 always welcome. 🙂

PS Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you think it's cool that I share the information with you, I would be happy about a small donation to the coffee fund. 🙂
