Q: Fractional temperatures for inlet and outlet temperature? #290

Closed bluberly closed 1 year ago

bluberly commented 1 year ago

When enabling monitoring on the Panasonic Service Cloud, the heatpump's inlet and outlet temperatures are displayed as fractional degrees with a resolution of 0.25°C. The downloadable CSV files also has the fractional temperatures

Has someone tried to decrypt the data stream from the heatpump and tried to find out if the fractional temperatures can be provided as well in Heishamon?

Hi, Fractional data is calculated by the service cloud as a function of time. The data is send from the panasonic only in integers just like heishamon is receiving it.

this is indeed a nice example. There where you see the integer change from 36 to 37 a few times per minute the service cloud calculates a fractional value.
