Hi @MartinViljoen,
I have found my issue!! 

If you check in the logs I send. I did not follow the instructions correct. 

 
Sending to http://http://192.168.0.87:8123  
So it never manage to send the information to HA. 

Not quite sure. This is bash script and i dont have much error control in it so when ever there is an unexpected string or int encountered it will give this kind of error. But looking at your log I suspect you have a semicolon at the end of your inverter serilal numbers. I.E Serial1;Serial2; Serial1;Serial2  , So its parsing Serial1 Serial2 then a blank serial ?
Seeing there are many request for better error control , sending settings ect I decided to re-create the addon using python which will be much better. Its almost done i'm in the process of testing it and adding the ability to send settings then I will make it available. instead of

I think I know what you mean now. Since the original post further developments were made.
On the SlipX card there is now a GUI, all you do go to each datapoint and search for the entity you want in order to link it.
You can also offcoarse opt to manually edit the SlipX configuration yaml file if you wanted to. (Not to be confused with Home assistant's configuration file) 
I.E 

 
What I meant in the first post was I named the entities to be similar to the slipx card (On a developer level) so its easy to map them. As a user you cannot change them. The naming of both addon and card also later changed slightly so its not relevant anymore.
