This flow implement the cloud based API from easee to communicate with the car charger "Easee Home". The API is documented and can be find here: https://developer.easee.cloud/docs/get-started
The flow includes the importents commands:
See comment "README" for start.
The flow uses . "node-red-dashboard" . "node-persist"

Hi,
It looks very advanced - and more advanced that what I am used to. Am I right in understanding that much of what is in this flow is only necessary if you do not use the Home Assistant integration of easee?
I run Home Assistance and have a working flow where my car charges on excess solar energy from my PV system. This works great, but I have two issues:
I have two chargers, so would like to see what other people with two chargers has done - especially on how to divide the solar energy between master and slave charger robot
If anyone has been successful in implementing the equalizer function in Node Red. I do have the equalizer, but I don't really like how it works dividing the excess solar energy. My Node Red flow works much better for this. That is why I also want to make the same functionality from Node Red. Due to my PV system I already have CT clamps and know how the energy is used on the different phases. So my question to you is. Do you have some functionality, that I could look into for inspiration on this. Considering that my above assumption on not needing a lot of the API/Token refresh you do in this flow?
Thanks in advance.
Great I managed to install it now.
I also your flow required https://flows.nodered.org/node/node-red-contrib-persist
Can you please update the instruction to include those 2 required palette?
