Z-Wave power-strip

Yesterday the Z-Wave power-strip I mentioned earlier arrived, in a light-weight large-size cardboard box mostly filled with air. After unpacking the air and reaching the bottom of the box, there it was: the GreenWave Reality PowerNode. Wow, I have never seen such a shiny bling-bling power-strip in my life 😉

Since Maarten Damen already discussed some of the software related aspects of this power-strip, I’ll only talk about my hardware related observations.

The power cord, which is 130 cm long, looks good. Thick and solid, like a power cord should be that has to supply 6 sockets. Personally I prefer straight plugs, but as most plugs are these days, the power cord of this power-strip also ends with a right-angled plug.

The bling-bling level of this power-strip is high; high enough for my son to ask “What’s that??”.  “A power-strip, my son.”  “Yeah dad, I can see that, but is there something else you can do with it as well, or what? Cause it looks so, ehh, unusual?” “Yes, with this power-strip I can switch off the TV in your bedroom from the other side of the world, ain’t that cool?”

 

The power-strip has a On/Off button and some sort of dial. Pushing the button feels a bit cheap; no real ‘click’; and a very soft push is enough to switch the power-strip on or off. This button works too easy for my taste, which increases the risk of turning the complete power-strip off accidentally. The dial feels a bit cheap too; in my opinion, there’s some imbalance between look and feel here..

The 6 sockets have child protection, feel solid and keep the plugs in place firmly enough. Each socket uses 45 mm of space. With a lot of adapters this can be a problem, as with all other power-strips I have, so this power-strip is neither better nor worse as a standard power-strip in that perspective.

A standard procedure for everything with a power cord that comes into our house, is measuring the standby power usage. With nothing plugged in, this power-strip uses ≈ 3.5 Watt. That’s about 30.5 kWh per year. IIRC that’s about 0.9% of the yearly power consumption of an average household. (in my case, that percentage is much lower 😉

So the first impression is OK. I’d love to see what’s inside, but that will not happen. Yet. First I’ll hook it up to Homeseer to see if and how it works before I open it up; so that when I close it again and the strip doesn’t work anymore, I know who to blame…

    How did your son respond when you told him that you could switch off his TV from the other side of the world 😉

  2. With a look on his face as if he wanted to say: “The game is on!” But I think this time he’s gonna lose 😉

    I Robert,
    Does the powerstrip is only for on/off or also measure kwh?

    • Hi Alex,
      There’s a link in the post to Maarten’s weblog, which gives you all the information you asked for, so i suggest you read his post as well. I was disappointed by the fact that the Total power usage did not match the sum of all the individual sockets, so I stopped using it and sold it. I don’t know what caused this strange behavior.. maybe it was caused by a bad Z-Wave implementation in Homeseer? I really don’t know. But if calculating a sum of 6 values is too much to ask for with Z-Wave, I don’t want to use it. OTOH, maybe things have improved since then… 😉
