I'm really starting to think about replacing all of my wemo switches. I have a surprising number partially because I acquired several from my brother in a swap.
I borrowed an IR camera from work this weekend to do a home energy audit and what amazed me was how warm the wemo switches get -- this is for the in wall one (but I have several plug in ones also) and they all light up brightly.
I plugged one of my spares into a kill-a-watt and it consumes 1W of standby power even when nothing is attached.
Yes, I know a watt isn't a lot but here in california the highest rate tier for electricity (which I always seem to end up in) in $0.32/kwhr -- That means I'm paying 1*30*24/1000*0.32=$0.23 per month for each switch
compare that to the lutron switches - I scanned my wall mount ones on the IR camera and it barely registers. I also have a plugin in lutron module and with the power off the kill-a-watt register 0 (I'm sure there is some power but it's well less than a watt)
The lutron module can also dim so it actually has MORE functionality (and integrates with my Wink hub)
I know that California has horrible energy costs so for most people it will be maybe $0.05 or $0.10 per month it's the thought that drives me crazy. #wemo #lutron #winkapp #homeautomation #smarthome
