Sanxing SX631/S34U18 electric consumption meter

I am now trying the possibilities and application of HA. I have already managed to achieve small things, but more complicated solutions are still a serious problem for me.

Before I get involved, I would like to know if the Sanxing SX631 electric consumption meter, which has a P1 port, can be integrated into the HA and if so, how?

Thanks and Regards
