Nest Audio Speakers in Stereo pair

[tr4nt0r]

Hi,

i have 2 Nest Audio Speakers that are paired together as stereo couple. In Home Assistant they are shown as Google Cast Group and the 2 speakers are also shown as two separate devices. PowerCalc does detect them and shows their stand-by consumption but they don't show any activity and so PowerCalc also doesn't show any power consumption except for stand-by. Only in the corresponding Cast Group i can see if the speakers are playing something and at which volume.
I tried to create a virtual power sensor with the Cast Group as source entity, selected Nest Audio from the library and set the multiplier to 2 but then it doesn't show any stand-by power consumption. Anything i can do about this?

What is the state of the Google cast group when nothing is playing?

the state is off

Very strange that standby power is not working for you. What is shown when you on the power sensor when the source entity is off? unknown, unavailable or 0?
Could you share diagnostics? You can go to the powercalc integration page. And at the virtual power sensor you created click three dots and "Download diagnostics".

Sorry, it seems i mixed something up, I'm totally sorry for the confusion. Actually it shows stand-by power, just not for both devices. The sensor shows only 1.8 W instead of 3.6 W. I think what the problem is, is that the multiplication factor is not applied to the stand-by power, only to the calculated consumption when the devices are playing.
