Virtual energy monitor device or equivalent?

I’m trying find a virtual energy monitor sensor (or equivalent) that will show point in time energy use. I have an ‘energyhive’ clamp and their website provides an API. I’m using webcore to pull the current kW reading from energyhive into a variable.
At the moment I am using the simulated temp ‘generic device tile’ and update that but this shows as a percentage so it’s not ideal.

Is there another virtual device type I can use that would be able to store an integer pushed from webcore?

Thanks for any ideas.
