Ok, I did some more exacting measurements ... looked up my current rates.
I knew my rates went up lately but man ... The costs in stand-by ... shocked me ...

In my area the cost of electricity: $0.354 / kWh ($0.192 / kWh is for the actual electricity and the rest delivery, fees, and taxes)

The Axiom actives (2x DSP/ADA1500) and 2 EP600 used 72 watts in stand-by. The other Axiom products in the HT (ADA1000, ADA1259, and 2 more EP600) used 54.5 watts. So, the HT Axiom equipment uses 126.5 watts in stand-by ... If I include the prepro, blu-ray player, Amazon Fire, Ethernet SW, and projector it's: ~144 Watts

Cost per year:
$446.55 to keep everything in the HT in stand-by
of which $392.28 is for just the Axiom equipment. $54.27 for everything else.
This is if I never use it and just use the tiggers to shut down.
Needless to say, this goes to zero if I shut off / unplug everything when not in use. I think I might have incentive here smile



Here are the approximate individual stand-by measurements: (averaging by eye ...)

Projector (LS12000): 1.2 Watts
AV8805 (prepro): 3.2 Watts
UB820 (Ultra Blu-ray Player): 7.2 Watts
Ethernet SW: 2.5 Watts
Amazon Fire (soon to be replaced with an appleTV box): 2.6 Watts

4 - EP600: 8.9, 8.3, 8.7, and 8.4 Watts, (Note when not in stand-by they use ~ 3Watts more)
1 - ADA1000-8: 25.3 Watts (this is surprisingly high ... too high ... I'm gonna email Axiom on it)
1 - ADA1250-6: 11.4 Watts
2 - ADA1500-5: 13.5 and 13.1 Watts
2 - DSP: 14.5 and 14.3 Watts (always on ... no stand-by trigger)
