I just realized my values are wrong.
The sensor read 9533 which was shown as 9.533 on the dashboard.
It should be 9,533 kWh.

I divided the sum by 1000 in line 183:
s = sum([y["value"] if y["value"] is not None else avg for y in yesterdays_consumption["values"]]) / 1000

The daily consumption gets reported on the next day. So today I receive the value for yesterday.
I would like to have an option to tell the integration to add the value for daily consumption to yesterday 23:59.

Sensors with the Longitude and Latitude attribute are displayed on the map in the Home Assistant by default. Can you delete these attributes or make them switchable? The icon overrides the home zone.

Hello, i've installed and configured your integration yesterday but unfortunately i do not see any data displayed in the energy dashboard. Is there any extra steps i perhaps missed? The entity itself does contain some data/attributes.

The log file also returns some exceptions

Hi,
I'm having issues with the login, immediately after adding the integration.
I've successfully copied the custom components over, found it in HACS, downloaded, restarted and tried to add the integration under the "Devices and Integrations" tab in Home Assistant.
The credentials I'm using work fine when logging in directly on the website, but I get an error "Username/password invalid" when using the same credentials for the integration.
What am I doing wrong?
Thanks!!

In order to better keep track of dependencies and stay compatible with potentially breaking changes of home assistant core,
we should

• introduce semantic versioning
• use package release of github
• add a dedicated github action or "step" for releasing those
• integrate the release management into HACS

This error originated from a custom integration.

Checking smartmeter homepage show the smartmeter dat even if they have not been updates since 2 months which is an other issue but from WN this time.
Have they changed the API again?

Hi DarwinsBuddy,

thank you for this great integration and for your effort.

I have a problem with the values I got. According to the integration the consumption was 9.822 kWh yesterday.
However the Smart Meter Webportal shows me 9.381 kWh. Previously I was also using the Vienna Smart Meter integration and there was always a gap between the values. What could be the reason for this difference?

My other question is related to the energy usage dashboard. I see either negative values or small differences between consumption of the day before yesterday and yesterday. As far as I understood SensorStateClass.TOTAL_INCREASING is meant for energy meters showing totals.
E.g.
Monday: meter shows: 10.000 kWh, daily usage: 10.000 kWh
Tuesday: meter shows: 15.000 kWh, daily usage: 5.000 kWh
The increasing value is the total consumption, the daily usage is the difference between those two values. A decreasing value means a new meter cylce. Since we already get daily consumption from the Smart Meter Webportal, this sensor class seems to be the wrong approach.

Honestly, I did not found a suitable state class for this scenario in the developer documentation. https://developers.home-assistant.io/docs/core/entity/sensor/

What is your experience?

I get the following error after adding the WNSM integration:

It seems that Wr. Netze updates the data unregulary with weeks between updates. Previous update was with data including 9th April.
New update visible on the smart meter portal was ~3rd May. However, in Homeassistant the new data is not visible, it is still stuck at 9th April.
Is the integration catchin up with older _statistics data when it gets new data?

          Please add a test for this

Originally posted by @DarwinsBuddy in #101 (comment)

Hi,

I noticed that the energy dashboard is one day off displaying the daily consumption data. I suppose this happens because

1. Integration gets the meter value for yesterday (at least for me) between 12:00-14:00
2. HA says "alright, so today's consumption is meter value latest - meter value latest-1" even though that's yesterday's consumption

Please see the screenshots for more details. I am not sure if this is related to this integration or rather to the way HA calculates delta values for aggregated sensors. I am still researching how I can change this behaviour for a particular entity in HA.

Right now, the API is logged in every time it is triggered. However, I think the token can be used for much longer time than 15min.
Is it possible to store it and re-use for longer time?

Hey there,

I'm not sure if this is the best, or even the right place to report this. If it isn't, please let me know.

I was trying to configure the WienerNetze integration, and noticed the v1.0.2 release 2 days ago. After updating via HACS, I now the get the following error.

I am not familiar with Python. I tried googling the error, but that didn't bring up any useful results. I looked into the Python documentation, but didn't find anything obvious either. I'd be grateful for any pointers on what might be causing this and how to fix it.

Hi @DarwinsBuddy
I have the issue, that the entity is not updating. When adding the lines to configuration.yaml and secrets.yaml, I get the actual Zählerstand of my smart meter but after that the entity is never updating.
Do you have any ideas why this is not working?
Many thanks!
Andreas

Detached from here: #89 (comment)

The problem can be, that measurements are delayed in the API and the next day enters the system earlier than the previous day.
That could then lead to days missing consumption data.

The biggest question is how they could be added, as the statistics import does not really allow to insert data between already inserted data.
One proposed idea was to delete all imported data back to the missing date and then start the import again.

This custom integration uses deprecated DEVICE_CLASS_* constants in its codebase.

The DEVICE_CLASS_* constants have been deprecated and replaced in Home Assistant Core 2021.12 (over a year ago). I would highly suggest updating/migrating this integration to the new enums.

For example, for the device classes supported by the sensor platform, there is now a SensorDeviceClass enum. So if a sensor previously used the DEVICE_CLASS_ENERGY constant, it should now use SensorDeviceClass.ENERGY. Other platforms (like binary_sensor, and number) provide similar enumerations for their supported device classes.

The migration thus only consists of replacing constants with an enumeration member and is, therefore, very low impact and should be fairly straightforward.

If I can help resolve any questions regarding this change or migration, feel free to ask or respond to this issue. I'm happy to help!

Kindest regards,

../Frenck

Looks like the API changed again. I haven't had any sensor updates since last Friday and when I enabled debug logging for the integration, I get this in the logs:

Not sure what failed there... Apparently the Location was in the header but not the &code...
I guess it would not hurt to put in some more checks in the login function, as this might be related to #23 (which is the exception just two lines earlier)

Hi!
Loving the simplicity of this and would like to contribute!
Unfortunately, it is not quite obious to me from reading the code how the api communication is set up and what the different endpoints provide. I see two different api tokens and have no clue how and what they are used for and how they are aquired.

It would be nice to have a bit of documentation about this to make it easier to get started!

Something like this would toatally suffice:

/api/zaehler

Example Request:

{
    "apikey": "asdf"
}

Example Response:

{
    "values": [1, 2, 69]
}

I can try writing some of this if you show me where to look :). Chrome Devtools on the smartmeter dashboard?

Crosspost from https://community.home-assistant.io/t/create-daily-monthly-yearly-reports-for-energy-consumption/476352/2

This is a question related to #20 maybe someone has an idea...
I tried to get a mean value for the daily consumption as a UI panel. However, I can not select Mean in the statistic panel.
Maybe that is because I do not import the correct data into the statistics table? Do I have to use the mean as well? But what use is a hourly mean when I want the mean consumption per day of, say the last year?
Anyone has an idea how this could work? Does it work at all?

Data is provided on the next day. So daily import of yesterdays 15 minute consumption data would be a nice feature.

I have three meters connected to ha via two different accounts.

T3 is running on the first account and shows the total consumption of the meter.

T14 running on the second account is defined in the "Wiener Netze Smart Meter portal" as "Favorit" and also shows the total consumption.
T7 is also running on the second account and shows the consumption of the last day (what i like much better than showing the total consumption). When setting this one to "Favorit" the behavior of Meter T14 and T7 flips.

Is there a way of only showing yesterdays consumption?
Thanks for your help,
Andreas

After adding the Integration & entering my UN/PW; I don't get any new Entities in HA - but some errors in the Log.
(I only did opt into the 15 minute interval yesterday & the values do look pretty strange/off in the wienerNetze online portal).

Screenie from the online portal:

(did defenitly not use 7000 kWh yesterday; probably the smart meter returned the aggregated usage since its installation in feb 2020?; before yesterday I have no measurements at all)

I'm sorry, I should have made this clearer. I am not using any sort of oauth, but an email and password directly when logging in via https://smartmeter-web.wienernetze.at/
The same credentials are rejected by the integration.

I noticed this the first time in the log.
I constantly get errors like Update of sensor.at10.... is taking over 10 seconds but that one is new.

The API is actually quite slow, but it seems that in this case, it hang in a request for over 15min - at least that is what I can reconstruct from the logfiles. 🤯

Probably it is a good idea to set a timeout in requests.Session.request to like 60s?

Hi,

I have connected my HA with this plugin via HACS to the Wiener Netze Smartmeter.
The meter with the "Bezug" I am correctly receiving daily.
I also have a second meterpoint for the produced PV. This I can see in the smartmeter website from Wiener Netzte and the integrations reads is correctly, but the data is always "unknown".
The attributes in the integration are correct shown.

And a second question: Is it possible to get also the 181 and 182 values instead only the 180?
thanks a lot for any help.
Mark

Instead of having a total sensor per Zählpunkt, it would be nice to have a sensor capable of providing the same granularity in measurements as WN delivers. Unfortunately, WN delivers them not as they appear, but merely once a day.

Find the right way in HomeAssistant to store those measurements in bulk for the individual 15minutes/hourly intervals per day, when the API is returning them finally.

Integration was working will since 3 days..

Maybe you can make the URLs configurable from the UI, because most of the energy companies are using the same API for smartmeter data.
Would be nice, so there would be no need to fork the repository for example in my case.

Hi @DarwinsBuddy

IDEA:

Make use of the Wiener Netze csv export endpoint
Implement an import of csv into statistics module of HA
hook it up to config flow (so it can be triggered on demand)
call it on initialization of the integration (when setting up the sensor)

Thanks @reox for this idea!

If I compare the data in the Home Assistant and on the Smartmeter website, the data in the Home Assistant is shifted back by one day, i.e. the 10.515 kWh from Friday appear in the Home Assistant on Saturday and the 11.313 kWh from Saturday appear in the Home Assistant on Sunday . Thus, the weekly total data displays are not correct! (see printscreens)
Please check it.

Added the attribute to the energy tab, receiving the following error:

for reference:
in the smart meter portal the "newest" data for my smart meter is from 15 days ago.
My data history starts on the 24. February 2023

Hi,
as the integration stopped working some days ago I realized there was a newer version available.
After the latest update it shows a high minus value "-3.164,95 kWh" for this day.
Do you have an idea why this is happening and how to solve this?
Is there a way to start from scratch? I tried to remove the integration and add it again but the value is still there.
Thanks in advance!

Hi teams,

thanks for developing this integration.

I get a correct value for sensor.at001xxx but it is not shown in my engery dashboard.

How can I get it to be shown there?

Thanks
Ralph

when activating the integration it would be fine if there is a switch, or a service, or a button, or any other way to trigger the import of historical data.

Could you please provide more information on how the energy dashboard has to be configured so that you can see the daily usage? After adding the integration via HACS, I am unable to get any meaningful data from the entity besides the total usage meterReadings:value and hence I assume the energy dashboard won't show anything either.

I checked my /welcome api result and it does show data in consumptionYesterday and consumptionDayBeforeYesterday so the issue must be with the integration itself?

Got the following Error message in the log file:

Since this was requested multiple times already, let's get going with it.
This depends imho on #35

which will alter the way we are setting up sensors.

Every now and then WN doesn't return any data or due to a sensor error we may miss days of usage.

Extend the sensor, s.t. it somehow recognizes which days have been missed since the setup of the sensor and try to pull them retrospectively

It would be great if the integration could support another Zählpunkt for measuring exported Energy towards the network i.e. from a PV

I have used the integration succesfull till yesterday . Today was my router changed because of any other issue. My Smartmeter was after the change unavaliable. I have deleted the integration, restarted the server and tried to reinstall. At login i am using "log wien" . Till today i did not have any problem with this method.

Ez a hiba egy egyéni integrációból lett származtatva.

Error validating Wiener Netze auth

Hello,

I have reinstalled my Home Assistant last week. With the old installation the reading of the SmartMeter worked.

Now when setting it up I get the following error:
"The configuration flow could not be loaded: {"message": "Invalid handler specified"} "

Can this possibly be related to the Python version (3.10.1)?

Kind Regards

Maik

Seems like another hick-up of the API...
