I have 2 of these, 1 on the mains and another on a pair of 220 legs for a split unit AC.
The one for the split will never go below 90 watts, even when shut off or on standby. I have an old non-digital clamp om Amprobe that report s under a watt on ea. leg when on standby.
The one on the main seems close, but no idea when everything off as I don’t want to shut down the house
Any one have any experience with these? Tried single leg - 45 ea. single leg and neutral on 1 clamp - same .
Really curious what this thing costs - but 90 watts minimum makes it useless.
