Total energy consumption of a house


KristianO

Question

Hi,

 

What is the best way to monitor the total house hold energy consumption?

 

- Id like to see the total in the web panel so as in the iOS gui.

- Id like the total to measured as a total and not to include individual devices such as fibre wall plugs.

- Id like the total consumption to be updated in a graph that can be followed.

 

Is this possible? Northg? Any other device? Restrictions from Fibaro?

 

Sounds like an obvious thing for home automation, but what do i know?

 

Thanks!

Hi,

 

I'm using a B-Control EM-300LR for this scenario:

For the consumption in total also the EM-300L works, the difference is the modbus-feature. The 300L is not able tor track consumption for single circuit breakers. The related software is open source, the included web server works well and stable and it comes with a 4GB storage included, what is far enough. 

 

The device is also available and labeled for other manufacturers like Busch Jaeger, ABB, SMA... Different Colors same product...

 

Other Product I found is from quibino:

It can be integrated within z-wave, but it is only one phase, for that you need three ones (regulary) and have no web interface. 

 

Best

Hi Kristian

I recently created a VD that does what you want to do.

Please login or register to see this link.

I used a Dutch product, the Iungo Energy Manager, that gets it's data from the Smart meter.

A lot of other products can be used for this, that can measure the total power usage via a Smart meter or a metering device with current clamps/coils.

The last topic calculates the total power minus the power from the modules and sends that to a unused relay for getting the value in the energy panel and graph.

  • Thanks! But I guess my real concern are that I don't have any graphs for the VD or that the total energy displayed in the dashboard is not really the total.

    It would be nice if I really could use the HC2 for all that.

    It show the total in the dashboards

    Dashboard is the total power consumption at the meter minus the measured values of the modules.

  • Sweet! So what you do is the extract the total energy from your "smart meter", sum up all your local "energy point" such as the wallplug and extract to get the total. You then fetch this total to an existing walls witch as "messasured" data?

  • To get this right, so where do I preferably place this "unused" switch? Did you create a room called "House"?

    I guess I can't use a fibaro fgs-221 and use one channel for real switch and the other channel for measurement only?

    Did you only connect L and N since you don't use it for control of anything?

    I guess this would be solved when plugins arrives and you could turn a vd into a pluggin and define it as a energy meter. Still dreaming!

    I have a FGS-222 (2x 1,5kW) installed, which is used as a single switch.

    So the second part of the switch isn't used. No input scwitch connected to S2, and no load connected to the output O2.

     

    I have created a section called "VD Panel". In that section I created a room called "Dashboard" where I have several VD's giving me a direct view on information that I want to know at this moment.

     

    The second switch is also assigned to this room "Dashboard". But you can also hide it if you want.

    Top right is the VD from the Iungo Energy Manager is given me all the details on Energy, Gas and Water

    Bottom right is the second switch.

  • Sorry, but i dont get it. eg. i have a 2x1,5 switch in my laundry were i only use the S1 connection. 

    I guess i could activate the S2 channel (Not used today) and also add power measurement for the Device.

    I guess i could use the S1 in the laundry and assign S2 channel to my Section "VD Panel" and a room called "Dashboard".

    This piece of code is doing the job.

    Please login or register to see this code.

    117 is the ID of S2 

    The relay must be "On"  (Energy-Devices in the screenshot)

     

    IungoUsage is a Global Variable with the actual value "usage" from the smart meter.

    Value is set in the first part of the script

    Please login or register to see this code.

    TotalEnergy is the sum of all devices with power metering.

    currentPowerValue is the value from the smart meter minus TotalEnergy

    currentPowerValue is assigned to power of device 117. This is done via API. The only solution that works
