Feature Request: make Efficiency, Irraditiation, Sunrise/Sunset, Frequency Numbers more senseful (round with correct precision) #914

good first issue
Good for newcomers
help wanted
Extra attention is needed
To quote C. F. Gauss (rumor has it that he didn't say it):
I propose to shorten some of the values to a sensefull number of decimals.
Examples are:
NOAANOAA calculates with 1 Minute resolution. I think, we should stick to this.In general no value shall be better displayed than the resolution of the raw inverter data. Rounding is fine, it is a kind of low-pass-filtering but adding fictive decimal places increases error noise like high-pass-filter.
I think, the resolution for Temperature, Voltages and Powers with 0.1 and currents with 0.01 is fine so far.
Efficiency and Irradiation with 0.1 % as said before.
Frequency with 0.01 should also be fine although Netzfrequenzmessung prints it with 3 decimals (20 ppm). I dont't think the inverter's time base would be that stable.
Power Factor with 0.01 seems also OK in my eyes.
Best Regards, Mark
