What has become the definitive solution Markus?

I want to forward the Smartmeter data to Influxdb.

Marchel, the screen shots do not show the code that you are using inside your function nodes. I can take a look at what you are trying to do if you paste that code into this channel (surrounded by 3-backtics ````` on their own lines).

Please do not share links to google drive files or images... most of us will not open files on the internet from people we don't know! Just paste them into this channel so they will be available for others to find/view in future searches.

Dear shrickus,

Thank you for your response and your advice.  
In the meantime I have found the site [https://regexone.com/](https://regexone.com/).  
Maybe I will find the required knowledge there for my project.  
If I still can't figure it out then I would like to ask for your help.
