Heat pump power consumption #31

I compared the heat_pump_power_usage to the power being measured by an Emporia Vue 2 CT clamp in the breaker panel. They definitely track together, but with about a 200W constant difference with the Daikin integration value being higher. Is there anything on the integration side that would account for the offset?

On my other heat pump same pattern, but the values are much closer: image

The Furnace power usage is a bit of a mystery. Perhaps it does not include the blower as the values are very low: image

This is the graph of the Emporia and Daikin integration ( at the bottom of the graph since the values are so low) together: image
