But I can’t figure out the constants 0.06 and 1.16 in the COP sensor.

I can see that these are broadly equal:
0.06 * 1.16 = 1/60 * 4.184

I think the 0.06 * 1.16 came from GitHub - raomin/ESPAltherma: Monitor your Daikin Altherma / ROTEX heat pump with ESP32, but figured I’d get a quicker answer here

Yep, came over from ESPAltherma GitHub default.

And as you’ve alluded to, it worked and importantly matched separate maths from direct sensors into EmonCMS so didn’t get round to changing it.
