Power measuring hierarcy.

[JanJoh 1]

Now, I have a copuple of wall plugs which reports power usage nicely enough.

Now i have plans to buy Z-Wave Clamp Power Meter (Three phase) and apply to my incoming mains. I also have plans to buy a second such unit to hook up to my relax (Sauna, in door jacuzzi and out door hot tub).

I think that will land me in a bit of a problem. Becuase if i understand it correctly, HC2 will interpret this like if the power consumption of my house is

Incoming mains + Relax + Wall Plug 1 + Wall Plug 2 + [...]Wall Plug N

Is that a correct assumption?

If so, the measurements will be totally off, since the correct total power consumtion is the valuse of "Incoming mains"; the rest is local distribution.

yes...i've also notified it, i've got problem too...

the value reported on device (power meter or wall plug) is correct, in a data rappresentation is totally bad because it sum all value...

Fibaro tell me end october update zwave network ....... i hope fix it...

I don't really see it as a bug but something that could be a nice feature

Hoping it will be implemented soon too

If the total power consumtion of the house is shown as the sum of all devices. It is a bug

The system needs to have some sort of "subsetOf" relation to the power devices. Ot at least a "isMainPower" flag for devices that measure the total consmtion.

Haha oke, if you state it that way. it's a bug

Experiencing the same issue. No solution for it since 2013?

I'm still suffering here with my Aeon Labs Home Energy Meter DSB28-ZWXX E2.

 

For some crazy reason the latest HCL firmware brings the unit into software as a Mult-Level Sensor (3-4 versions back, it had its own dedicated template).

 

Unfortunately it pulls in a random number as the main device, and then my actual first clamp data is added to that.

Unticking the "Show energy consumption measurements" does nothing and the total is still added up incorrectly.

 

So annoying since it used to work, even though the energy maths is a little vague. Would be nice if there was a panel so you could choose what to include for your total energy data.

Hello,

 

Has this been solved? My total reading seems to be doubled too (attached).

 

I use Aeon Home Energy Meter DSB28-ZWXX E2 -> single phase

version 1.16

 

Thanks

Hi,

 

Probably not a real answer, but I have my Smappee HEM and some wall plugs and a couple of Double Switches and I get exactly what I want. Just needs a bit of LUA  .
I made a VD that gets the HEM consumption info and puts it in some variables (Smappee has no official Plugin or anything). To get that info into the power consumption graphs, I put the data from my Smappee into the "power" from an unused switch (since a VD cannot have power consumption) minus the usage of all other power measuring devices.

So, my total is the total for the house and my plugs and swithces report their power consumption as well.

 

Looks like this

 

Algemeen = HEM - all other devices

Bart = My computer desk plug (uses a lot of power  26% of week total)

Living = My TV, ... plug

Inkomhal, Voordeur, Dressing = Double Swithes for some LED lighting.

Hi,

could you share the VD?

My Smappee VD is

, if that is what you mean.

Perhaps a simpler method is to create a room called something like MDC (Main Distribution Cabinet) and have the HEM placed in that room?

 

Well, at least this is the approach I have been thinking before I jump in to purchase the HEM to truly understand the entire household's electricity utilization. And it may be a good reading to have to compare against the power company's meter.

 

I know I had an issue at my old house (>20 years old) where the power company's meter has not been re-calibrated for >15 years and when there was hardly anyone home for months, the bills still amount to about the same for those months. Flagged to the company and they finally replaced the meter and rebate some amount (at their own discretion, not really scientifically calculated).
