Node-Red for Control Loop Experiments

[baal86]

Warning

Do not use this unless you know what you are doing. This is experimental and highly specific to my setup!

To play with control loops a bit more I have tasked the AI to port the core protocol of the CT002 to node-red. I have then modelled my own very system

• MQTT based grid sensor
• Two B2500 batteries

I had to hide a few credentials and MQTT topics are specific to my system. Check the node properties and $env if you want to play.

This actually works for me but is of course missing most of the features of AstraMeter. This is not intended to be an alternative to AstraMeter but rather a sandbox for quick experiments. I will use this to play with the control loops and different control schemes and submit them to AstraMeter.

flows.json

That file is all there is. I am running it on the node-red app in Homeassistant. If I figure out a good way to generalize node-red flows I might make a repo for it some day.
