Configurable energy update interval

[mattprecious]

Is your feature request related to a problem? Please describe.
It seems like the energy sensors only update once every 30 minutes despite each packet containing an up-to-date energy value. This is problematic for the energy dashboard since hourly breakdowns for device usage are not accurate unless the update lands right before the hour rolls over.

Describe the solution you'd like
A configuration option to adjust the update interval or remove the throttling entirely.

Describe alternatives you've considered
Removing the throttle altogether without a configuration option? I assume it's there for a reason though.

I edited the update interval to 5 minutes on my instance and have been running that for the past 6 months with no issues. With the work being put into the energy dashboard these days, it looks very clunky to have kwh readings roll to the next interval which displays a bunch of overshoots and undershoots. The 5 minute interval I am using makes the energy dashboard work great.

I removed the interval from the sensor entirely and haven't had any issues: mattprecious@d9d568d#diff-4d87651124803b62540021e21d99ff8cd4a46f145121833d313be2b5a2591c22
