Changing p1 kabel to Homewizard

As my current P1 USB cable is several years old, and almost breaking apart, I was looking for something new. I also saw the Homewizard p1, nice little WiFi thingy and seems to work without account, after opening the api.

Is the P1 from homewizard good? And what will it do with my energy dashboard after chaning? Do I get a dip? Or even complete new data? I don’t want to loose data from last year.
