The European Union has decided that every house in Europe must be equipped with a Smart Meter. Here in The Netherlands the electricity company are replacing the old ones house by house, so it will take some time to replace them all, but that will be done before 2020.
It is possible to speed up the process by requesting a smart meter at some cost. Since I have an electric car, I thought I needed the smart meter for it, since the charging station can detect power usage of other equipment at home. I am charging the car at night, so no real issues fortunately. But the smart meter was ordered beforehand, so let's make use of it 
Here is what I am going to do:
1) Connect the Smart meter via a P1 port to Arduino Uno (one of the many ways to get telegram messages from the Smart Meter);
2) Create a database (mySQL or MongoDB) and write a script for the Arduino to push every xx seconds a telegram message into the database located at my NAS;
3) Develop a service to request information from the database (NodeJS or php);
4) Develop a ui5 application to retrieve the information from the service and display it.
Waiting for the hardware to arrive
