Average pump-starts

Apologies if this question made it to the incorrect part of this forum, it’s a Z-wave device and I didn’t find a better spot. But happy to be moved by admin.

I have a drain pump connected to a z-wave device that measures the power consumption. The pump has a level switch, when the water level goes high enough, the pump starts and the z-wave device show consumption as per picture below:

I would like to create something that let me track how many starts per hour the pump does (based on say the average last 10 starts)…

Any ideas?
