Energy Management in Home Assistant

Glad you found your HA-solution on your old analog meter.

That statement is not true, the are some digital meters with a single meter which do/did not reverse (got one years ago at the same time 4 solar panels were installed) but in principle you should get a SMART (read big brother is watching you) meter consisting of (4) separate meters. Two of them will report your production to the grid, which are you returns (likely before “saldering” roundish 60-70%). This kind of meter will work seamlessly in HA. And yes, The subject of “saldering” and your obligation (*) to report you solar panels is a completely different topic.

Aanmelden zonnepanelen wettelijk verplicht

Volgens de Europese en Nederlandse wet- en regelgeving is zonnepanelen aanmelden verplicht. Deze regelgeving is vermeld in artikel 40, vijfde lid, van Verordening (EU) 2017/1485 (de System Operation Verordening).

BTW for argument sake I dislike the upcoming changes in the “salderingsregeling” too (if you live in the Netherlands) but again this is a completely different topic.

All my solar systems is installed since more than 10y and it’s know by the authority. So I don’t have any issue. This is just the rule they applied, either you choose the taxes based on your inverter power (1Kw = 108eur) with the old gen counter or you upgrade to numeric without taxes, with reinjection for ridiculous price and keep just energy groing when you take from the grid, no more reversed way like old gen.

Ah, those are the rules in Belgium, right? I understand why you want to keep your analog kit…

zigomatic · August 5, 2023, 7:13am

Correct, Belgium with ridiculous amount of sun

We are charged a utility cost each day regardless if we use electricity or not.

How do I add this fixed cost to the energy panel so it adds it to the total cost.

OzGav · August 28, 2023, 3:28am

Use a template sensor to add it all up for you but some people (like me) are having issues with what is displayed on the dashboard How should i use "Use an entity tracking the total costs"? (Currently comes through negative) - #4 by blalor

Zilla · January 9, 2024, 2:02pm

Can it be added a gauge card to the energy daskboard to report and track over days the offpeak usage ratio over total imported energy?
It has a lot of cost and energy saving benefits.
Cheers

Hi all,

Love the system and love the intergrations, dashboards and metric. Due to some failed messages my storage was full and my database corrupted.

After alot of work an effort i got bigger storage and running it again. But now i have the following problem:

21-01-2024 evertyhing is oke

22-01-2024 i get bad data

The insight of the bad data

Day after it keeps working like normal

Because of the faulty data of 22-01-2024 my yearly overview and monthly for januari is broken.

How can i fix this… or what are my options? im thinking of deleting everyting from 31-12-23:59:59 and just skip form those metric to the current p1 data. It should have the sum of all up untill now.

Is there a way to find this false data? and edit/remove/delete the specific data?

kleinerhobbit · February 17, 2024, 10:53am

You should be able to find the faulty data in the statistics tab in the developer section.
Search for the sensor and finde the right timespan. Then you can edit the values.

BebeMischa · February 17, 2024, 3:06pm

The solar panels production (yellow) and gas usage (red) are both negative values. That per definition is not right. Why? I don’t know. But they have to be positive values.

edit:

Actually all your sensors have negative values…

They all should be positive:

Hapjespan · February 18, 2024, 11:03am

i know, cause of this faulty data at this exact moment my overviews are bad. but 23-01-2024 it worked as it should.

So i need to get rid of the faulty data.

Hapjespan · February 18, 2024, 11:12am

that did the trick, didn’t know you can do it within HA.

mr-gosh · March 28, 2024, 11:37am

Hey - that works perfectly - yiu just need to change your device-serialnumber…
Du you see a way to integrate the % of the battery charge into that view? Couldn’t find a variable to put the fill-state in…

ramdisk · March 28, 2024, 1:31pm

how do you show the gauges on the right edge?

I used the volkszaehler project - especially the vzlogger: howto:getstarted [wiki.volkszaehler.org] for the powermeter:

but I grab the information via this config entry:

Thanks but I was talking about these gauges

ziepoeskenetnie · April 10, 2024, 6:35am

Any one else having trouble with Shelly EM?
I guess since i updated ESPHome yesterday, my Shelly EM is offline, but it keeps tracking usage?

Here you see a big gap.

And here it’s just tracking energy usage?
I don’t understand.
I have cut power from Shelly but it doesn’t solve it

ziepoeskenetnie · April 10, 2024, 1:03pm

Was a wifi issue, all fixed now.

ialexyi · April 14, 2024, 5:48pm

Hi,

I am not sure if this a right place for this request.
But, there is a little issue, while configure the battery instance and the grid. The only two entities is involved, the ‘Grid Consumption’ and the ‘Home Consumption’. So, by configuring the Grid section with the ‘Grid Consumption’ entity and the battery section with both the entities, the Energy Dashboard does create two different grid consumptions. In this case there shouldn’t be a connection between grid and the house.

Please advise how to tell the Energy Dashboard that’s the same entities and it needs to be linked as a single one?

moritzgoebel15 · May 19, 2024, 10:48am

@fhopley Can you please share some code details on your dashboard?
