Hello,

 

This is an example of Savings graphic generated on the Energy Panel along with the Energy Balance for the same day (09-02-2022). At the moment the balance is simply calculated by subtracting total day Consumption from total day Production. I wanted to go a little bit further and was interested in knowing the effective amount of grid energy consumed (Balance -) and the wasted amount of solar energy produced (Balance +) and injected on the grid. From my understanding this would have to be done by calculating the complex area of these red and green shaped graphic figures (mathematic integrals). Is this feasible, could we have it in a future update or is it way to complicated to even waste time with it?

Good afternoon, I am in the same situation, in Spain we do not have net worth, which I mean by this: In Spain as is my case I have a self-consumption installation at home, I generate electricity from solar panels and consumption directly and if my house does not have consumption and continues to produce it injects it into the grid, I buy electricity at one price and they pay me at another, then the HC3 energy system does not help me much since the energy I consume directly from panels does not count it (it only the one I produce in its entirety and the one I consume as a company counts) but not the one that I self-supply, in my opinion it would be nice to add one more field in the energy panel and it will be like this way: energy produced, exported energy, energy purchased and energy consumed by the house, I think that way you can be played much more with the scenes throw for energy

The energy panel works this way: set the main energy meter(s) in the settings -> general tab, this is the smart meter data for example. Save the energy consumed and energy produced to the correct type (devices) with a QA or use a zwave device that does it for you.

 

When the main energy meter is set, the energy panel automatically substracts the energy metered on the (zwave) devices from the main energy device and the difference is tagged as "rest" in the graphs. Now you see the production, and energy consumed and the energy panel calculates if you have energy overhead or not (overhead is send back to the grid).

 

I hope this helps you with your problem.

Hello, thanks for your reply, I have some doubts...

 

What do you mean with the "energy metered on the (zwave) devices"? Not all my home devices have meters... Let's just imagine I have a 1Phase meter for my energy grid and another 1P meter on my solar production.

How would it work according to what you wrote?

 

From what I see on the energy panel, the Balance value is obtained by subtracting the Production from the Consumption, I don't think that any overhead is being taken into account, but I can be wrong...

Set your 1Phase meter as main energy device in the HC3 settings. Then energy reported from your z-wave devices will be substracted from the value the 1Phase meter reports (all energy consumed) and the Energy Panel calculates automatically the "rest" (what is not reported by devices because you don't have a zwave actor on every device in your home).

 

For example, your 1Phase meter reports 10 kWh energy usage for the whole home. Your z-wave devices report 7 kWh in total. The Energy panel reports 3 kWh as "rest". Also the main energy device is not reported in the top 3 consumers.

What I don't understand is: "Your z-wave devices report 7 kWh in total"

What is measuring my z-wave devices consumption?

That's the energy reported by the modules, like Fibaro Dimmer 2, Switch, Wall-Plug...
