1min sensors different device class / unit of measurement to 1d and 1mon #179

Hi, I'm assuming this is an issue - apologies if I've misunderstood.

I'd expected the 1min sensors to be the same as the 1d and 1mon sensors i.e. device_class = energy, unit_of_measurement = kWh, but the 1min ones show as power / W instead.

Is this a bug?

I was planning on building some calculations based on the energy usage in each 1min period, but that relies on it being kWh instead of W.

Not a bug, the 1 minute data is the same as in the app: the average power over a one minute interval. To convert to energy you just need to multiply by a time, ie 2500 watts over a minute uses 2500W 1m 1hr/60m = 41.67 Watt-hour. Kilowatt-hour is just divide that again by 1000, ie 0.04167kWh.

Thanks, I'd not spotted that, thanks for clarifying
