I wouldn't call polling an event, but I get the idea.

I think that could work for a lot of meters indeed. I didn't check which
ones would fail, but that might be acceptable.

That may sound even to be the good direction to me.

With your Event recording work on the way, I would envision a future
where we could avoid entirely the Meter storage and compute the meters
dyamically via the API based on Events. So we would store only Events.
Meaning that if we "transition" our current polling code to passing via
an intermediate Event format before Meter, we're preparing for the
future.

Thoughts? :)
