Smappee Consumption Load Token

I have a Smappee Power Monitor, read lots of technical stuff, but cant find a step by step on how get a Client Secret, which I think is a token. Has anyone done this?

Please contact to obtain a client id and client secret

So everyone knows its $5.00 per month for 24 months to get a client ID from Smappee in order to upload consumption for private use.

Thanks for the update, its unfortunate since there was no charge a while back to access the smappee API

New quotation received today for 2y non-commercial API license for 58 EUR incl Tax.
So approx 2.5 EUR/Month.
