Arduino and electric prepaid meter

Using Arduino Project Guidance
1

Hello,

As part of a project, I would like to measure the electricity consumption of a prepaid meter. An account number is associated with the meter. The meter comes with a device that allows via codes to see the consumption of last month (801), the previous day (810) etc. I would also like via arduino to have this data by entering the codes 801, 810 etc.
My problem is that I do not know how to do it. Which arduino is ideal? Which modules are used?

Here is a link (We wait until the screen shows Connected then we put codes.

Thank you in advance for your precious help.

Here is a manual for a similar device. I've just glanced at it. http://www.inogate.org/documents/10.1_User_manual_of_Single_HXE12-KP.pdf
You first have to find out what transport it is using (Infrared, IP, Powerline etc.), then look at the protocol running on top of that.
Unless you have been given a password, you'll probably find that the control unit is somehow cryptographically paired with the meter and you'll have no chance to emulate it with an Arduino.
