Shockingly noticed that our home electrical bill is a big expense these days, so spent some time with a Kill-a-Watt meter. Figured might as well do some DECA testing! H21-200 with no DECA: 17 watts H21-200 with DECA: 22 watts HR21-200 with no Coax attached: 24 watts HR21-200 with Coax and no DECA: 28 watts HR21-200 with Coax and DECA: 33-34 watts Network DECA with PI: 4 watts In summary, looks like DECA uses 4-6 watts depending on the config. BTW, since I automatically pay our electrical bill, hadn't looked at the billing for a very long time. Was shocked to see how it's been rising. Huge numbers at 20 cents per KWH. Summer: $400-500/mo. Gotta find a way to go GREEN. Starting today!
