Since SENEC Application v0825,v0826 & v0827 no STATISTIC data is provided [No Data for multiple Sensors]

[marq24]

Problem

When your SENEC.Home will be updated to v0825 (also after the update to v0826) the integration is not able to provide data for a couple of sensors..

Affected Sensors (that's all the total sum data displayed in kWh):

• House consumed
• Solar generated
• Battery charged
• Battery discharged
• Grid Imported
• Grid Exported
• Wallbox charged

The reason behind is, that SENEC has decided to exclude 'STATISTIC' information from the response of the 'lala.cgi'... That's quite sad, since these sensors are mainly used for the Home Assistent Energy View...

Right now there is no quick fix to this situation - but since also data for 'DISPLAY' is missing my guess is, that SENEC is just building so called Banana-Software. Without "DISPLAY" information from the lala.cgi the /Display.html does not work at all - so I have hope, that the empty response parts have slipped through QA/QC

Current Solutions to access your statistics data

Please read the complete post/Issue text - since at the bottom you will find important information for you Energy Dashboard

'mein-senec.de' WebAPI

UPDATE 2025/07/15 THIS IS NOT WORKING ANYLONGER with the WebAPI part of this SENEC-Integration

When you update this Integration (ha-senec-v3) to the latest version you have the option to add an additional integration entry. When you start the process you have to select 'WEB.API: mein-senec.de Portal (usable with all SENEC.Home variants)' from the selection list and then provide your mein-senec.de credentials. This will add 13 additional Sensors to your Home Assistant (currently wallbox data is missing - cause I don't have one (yet)) - when you know the fields in the web-api - just let me know. Thanks to @mstuettgen!

Mapping lala.cgi to web-api Sensor names

Please find below a table comparing the sensor names between the classic integration and the web-api based integration - this comparison assume, that you did not change the names ['senec' & 'senec_wabapi'] since they will be used as prefixes

Name	lala.cgi based	web-api
House consumed	sensor.senec_house_total_consumption	sensor.senec_wabapi_consumption_total
Solar generated	sensor.senec_solar_total_generated	sensor.senec_wabapi_powergenerated_total
Battery discharged	sensor.senec_battery_total_discharged	sensor.senec_wabapi_accuimport_total
Battery charged	sensor.senec_battery_total_charged	sensor.senec_wabapi_accuexport_total
Grid Imported	sensor.senec_grid_total_import	sensor.senec_wabapi_gridimport_total
Grid Exported	sensor.senec_grid_total_export	sensor.senec_wabapi_gridexport_total
Wallbox charged	sensor.senec_wallbox_energy	-not-implemented-yet-

Riemann Sum Integal Platform

AS WORKARROUND you can add the following section to your ha configuration.yaml (if you have already a sensor section obviously you just need to add the sensor's itself) - unfortunatly the the integration platform does not allow to provide icon's - so you have to edit them manually later via the GUI (if you need/want them)...

Please note, that the source sensor names based on the default integration name 'senec' - if you modified the name during the initial setup you need to adjust the source sensors.

Handling the change of the EntityIDs in the Energy Dashboard

Since we have the situation, that some SENEC.Home Systems still return STATISIC data (since they are not updated) and that this data might come back with another Update - who knows? - the EntityIDs of the new Sensors (that have been added in both cases (WebAPI or Riemann)) are different by purpose.

When you want to keep your historic data in the Energy Dashboard (and I guess you want) then the current known best way is described here in an additional issue: How to configure Energie Dashboards (after SENEC.Home have been updated to 0825+)

Oh no ....

[neubi4]

If i got is correctly, these are all "daily usage" statistics data, e.g. how many kWh House consumed today.

This should be replaceable by using an Home Assistant Riemann sum integral (https://www.home-assistant.io/integrations/integration/#energy) which simply can summarize House Power (W) to kWh like in the linked example.

Since this counts infinitely higher, to get an daily used you can use Utility Meter (https://www.home-assistant.io/integrations/utility_meter/) to get an sensor on the integral which is resetted daily/monthly value.

These Utility Meter sensors then could be used in Home Assistents Energy View.

We cloud provice YAML examples for this in the readme of this repo.

[neubi4]

After looking at the old data, it seems that the Utility Metern is not needes since the old data also only counts upwards infinitely.

So it should be fine only using the Riemann sum integral sensors. I will try this.

FUNNY - while I am tyring - you already provide the info...

the values (that are still available in my environment) are constantly growing - so there is no need to reset them on a monthly/weekly/daily/hourly basis - so looks like using the suggested integration from @neubi4 sounds like a decent replacement...

Once the http-v3 build is confirmed as "working" I can spend some time working on example yaml parts that you can copy&paste in your ha configuration.yaml...

[electricdelicate]

Sounds great, thank you for your support!

[egonkab]

hello marq24,

thanks for your hard work. It works very well.
I use Powercalc to calculate the total sensors, this also works well.

[sigcarunchio]

Hello marq24, just discovered your fork after firmware update, great work!

1. About missing entities, i also redo them using custom sum integration templates, but instead using yaml code, i use helpers; do you think it's the same?

2. My problem is that i have a master and a slave senec v3; i think that missing statistics gave already total values, now (but i confirm this later) with custom sensor i have only data about master senec (the one that i register in the integration); do i need to register also slave battery and do total custom sensors?

3. Worst thing when i change sensors in energy panel with custom ones, I LOST all past data of about one year!!!!! sigh!!!!

anyway again great work, thank you!

[neubi4]

Hi @sigcarunchio

1.: yes, using Helpers and the yaml code is the same.

3.: i left the old sensors with their current VARIABLE_NOT_FOUND value in the energy dashboard and only added the new helper sensors. This way i still have the old stats data in my energy dashboard.
I dont know exactly how the dashboard works internally, it is possible that readding the old sensors will not work for you.

2.: This is an interesting one since not many users have multiple systems. Does the slave senec also has an seperate IP and the webinterface? If yes, then i would try to add the slave additionally to the master.
To get the total stat values of both systems, you could try to calculate the sum of the values from both senecs and calculate the Riemann sum integral on this value.

[sigcarunchio]

2. Yes, it has a separate IP with the same web interface, try this way!

3. Ok, i replaced them, try to reinsert also old sensors

[sigcarunchio]

Readded also old sensors, past stats availables again!
As soon as i will add also slave senec, I will report if it works

Good job, work also like a charm.
One question, is the "Riemann sum" exact enough for a proper calculation?
I will compare that to the Senec App.

I wrote a cautioning comment over on the old integration about Riemann sums: mchwalisz#47 (comment)

So here just a short summation: Riemann sums will start to differ from what the battery reports with time and a better solution would be to simply get that data from mein-senec.de.

mein-senec.de only updates every 5 minutes, but it's only for the totals, so that should be fine. The other values can still be queried from the lala.cgi if possible.
