Energy Dashboard (Build in)

[FireWizard]

Good afternoon @MYXOMOP,

It looks your are a creative designer, or is the image of that clown simply stolen from the creativity of someone else?

Keep in mind that Domoticz is opensource. You can use the software for free and except of the needed hardware, no costs are involved.
Opensource means also, that you have the possibility to change and to improve the code yourself. If you share that work with the community, everybody is happy.

However, if you dislike Domoticz for its design, you may move to another solution.
A lot of people prefer Home Assistant and the have an Energy dashboard, as well.
It looks like:

Just this afternoon, some commercial advertisement has been dropped in my mailbox.
They had also an Energy Dashboard. The solution will cost you 999 Euro.

You like it, then buy it.

So the community is now very curious for your revolutionary new design of the Energy Dashboard.

Regards

In general, it was a joke with a hint of criticism. I only use Domotics as a dashboard, and I like its graphics. My main smart home system is the free and highly professional HOMEd system from a programmer who is a C++ genius. Therefore, I have a choice among free programs.

I hope many people here understand humor and criticism.

Hi @MYXOMOP

You said:

Yes, I do.

But, you know the saying: "You must not look a gift horse in the mouth".

B.t.w. What is HOMEd. I tried to find it, but did not succeed, yet?

This is a highly classified Russian project, only to be read through an online translator.

Sounds like you have some frustration and assume you will "fix" this with a nice PR that will show a shiny new page?

I found the source of the design and the white background. These are children's coloring pages.

My reply is no longer needed as Firewizard' s responses were spot on.

Morning all. Just getting started with the Engery Dashboard here.. See attached picture.

My "Usage L1+L2+L3" parameter shows a total usage of my devices of 414W, whilst the P1 meter shows a flow of 638W to my home.
Do I read things wrong? Who can enlighten me?

Thanks in advance!

BR,
Marc

Maybe due to different time lags?

[waltervl]

Indeed probably a timing issue. The P1 meter shows -2082 Watt, the sun generates 2720 Watt, so then the dashboard calculated there is a usage in the house of 638 Watt.

Is L1+2+3 also coming directly from the P1 meter or is it measuring something else? If coming directly from the P1 meter is is a little bit strange it is so different.

[vlimper]

@waltervl Yes, L1+L2+L3 also comes from the P1 meter indeed. That's why it confused me. But like imautohuttraeger mentioned, it's probably a timing issue. Thanks for thinking with me.

I like the introduction of an energy board!
I have the solaredge modbustcp installed.

Only my total solar production I have calculated from the inverter + battery:

solar = inverter + to_battery

home = solar - (export - import) - to_battery

When I fill the values in the settings sheet the battery displays well, but the and the home values which are calculated by domoticz are too low, it ignores the Solar total value that I calculate.

I check these values with the solaredge monitor (have installed batter + in and export meter)

Hi,

The calculation by Domoticz does indeed not take into account the actual power consumption of the ‘house’. The actual power consumption is that supplied by the panels&battery (1) + supplied by the grid (2).
(1) cannot be obtained from P1
Have you been able to find a good solution?

[waltervl]

The energy dashboard calculates the power consumption of the house based on the values from grid (P1), solar and battery devices.

[dime]

The energy dashboard calculates the power consumption of the house based on the values from grid (P1), solar and battery devices.

Thank you for your response waltervl!

Nevertheless, I still cannot balance the calculation in Eboard. Eboard seems to take the delivery to the grid from P1 as its starting point, not that from the panels, regardless of what I select in the Eboard settings. I always end up with an amount of power (the difference between the panels and the P1 delivery) that, according to my calculations, is vanished like the sun behind the clouds. And I'm not talking about a few watts, or due to time synchronization.

[waltervl]

Just select what should be selected and it works (for me).
If P1 is using 1000W from grid and Solar is producing 1000W, the house is consuming 2000W
If P1 is returning 1000W to the grid and Solar is producing 2000W, the house is consuming 1000W.

I guess that user "dime" has similar problems like me. Formerly I just a plug and play small solar power plant and the energy dashboard worked perfectly. Later I have installed a big solar plant with a SolarEdge inverter an activated solaredge modbus hardware to domoticz. With this, the figures are not correct and due to little time for it I gave up figuring out. Somehow, the Modbus figures from SolarEdge do not deliver the current pure solar power.

[waltervl]

I have 3 solar plants and I combine those plants into 1 total Electric (instant+counter) solar production device and that works just fine. The dzvents script for combining multiple solar plants are in this discussion.

The calculation is very simple, it is the sum of grid (P1), Solar and Battery. Sometimes people have mixed up their Domoticz devices direction (eg Usage is in real Production) and the calculation goes wrong.

[imautohuttraeger]

I haven't combined my big plant with the small plant. The problem also occurs, if I switch off the small plant.

The modbus "power" figure from the SolarEdge inverter is not showing the pure solar panel production. It seems to minus batterie discharging and add batterie charging, so actually a virtual device must be created from that. But every calculation fails, because there seems to be even more influencing factors which I cannot describe and which doesn't feel logic to me.

However, currently my time for debugging is very limited (and I am far away from really knowing what I am doing ), so I gave up and look ahead to maybe use an already installed Shelly 3 EM as a source of information instead in the future. But u fortunately MQTT results of this device doesn't show power in watt but only voltage, current and power factor. So I have to calculate this via script an feed a virtual device wit it. But I don't have a "copy - paste" pattern that I can use for adjustment.
