Compatibility between Landis and Gyr Smart meter (model E450) and Homey dongle

I wonder if the Landis and Gyr smart meter E450 is compatible with the Homey dongle? This dongle is suppose to be connected to the P1 port of the type RJ12. However, on the description of the SM E450 I rather see a P2 port?
Here is a picture of the SM E450

Many thank for your help

As an alternative for P1, yo can use the blinking LED, there are devices for that to read-out.

many thanks for your helpful suggestions. There is one point which is not clear to me yet. Assuming that i use the GplugM dongle, I would like to monitor my energy consummation for one full day. Would I need some additional device like a computer or disk ro store all the data delivered by the Smart meter? Or I am missing some information in the use of the dongle?
your help on this would be greatly appreciated

No idea, you have to ask the manufacturer of the dongle…

Guess the app power by the hour wil be compatible.
