SENEC WebAPI cant add/reconnect to

[indikat0r]

With which version of the integration you have an issue?

WEB.API: mein-senec.de Portal

Multiple Systems Environment?

• I have multiple SENEC Systems (master/slave configuration)

Checklist

• I have installed the latest release (or BETA) version of the integration and home assistant.
• I have prepared DEBUG log output (for technical issues) | In most of the cases of a technical error/issue I would have the need to ask for DEBUG log output of the integration. There is a short tutorial/guide 'How to provide DEBUG log' here
• I understand the SHIT-IN - SHIT-OUT principle (in case of implausible data) | It will happen, that the data that is displayed by this integration does not make much sense (to you) - Of course this could be always the case, that something in this integration has been messed up - but so far - in all reported issues the root cause of implausible data was/is, that the SENEC.Home device itself already provided this data
• I confirm it's really an issue | In the case that you want to understand the functionality of a certain feature/sensor Please be so kind and make use if the discussion feature of this repo (and do not create an issue) - TIA

Add a description

Hello,
my WebAPI intgeration stopped working.
I have removed it, and now i cant it readd.
i have added the Debug Log.
as far as i understand, the url returns empty data?

Add your DEBUG log output

[REMOVED LOG cause of privacy issues - but I have a copy]

[marq24]

a bit tricky from the log output to tell what's going wrong (since local access is also running) - nevertheless - please update to the new release...

Is there another way to get Daily Total Generated Value? that is the only reason i would need webapi...

[marq24]

What I don't understand is, that the APP-API requests run into an timeout - looks like that the master_plant_id that is received during the initial setup is not the correct one [253699] - can you check in the webportal what's listed there as your number?

And if it's different - then please: a) let me know the 'correct' one & b) remove the web-api part again - enable debug logging of the integration - and then add the web-api part again - and send me (by mail) the complete log output - I hope there are traces from the correct number...

Also something you might like to check, if there are no internal firewall's DNS-blockers running in your network - I assume the default Senec (MobilApp) still works fine?

[indikat0r]

Where and how can i find my master_plant_id?
is it: "Seriennummer Steuerung" or "Gehäusenummer"?

and yes, app is working and from my PC i can open mein-senec.de and login...

[marq24]

I am sorry - just checked myself, if I can find my master_plant_id on the mein-senec.de website - or in the requests/responses - but had no luck :-/ -> looks like it's time to use Bruno (aka Postman) and debug your account...

[indikat0r]

Installed Bruno and found that on google:

https://www.postman.com/blue-moon-277072/senec-workspace/documentation/4940eni/senec-app-api-4-3-3

And thats what i get:
[ { "id": "253699", "steuereinheitnummer": "XXXXXXXXXXXXX", "gehaeusenummer": "DE-V3-H-XXXXXXXXXXXXX, "strasse": "Am xy", "hausnummer": "xyB", "postleitzahl": "xy", "ort": "xy", "laendercode": "xy", "zeitzone": "Europe/Berlin", "wallboxIds": [], "systemType": "V3" } ]

Seems correct, if i am correct

Will send you an Mail with full Log

[marq24]

and can you also do a request to:

https://app-gateway.prod.senec.dev/v1/senec/systems/{{SENEC_ANLAGE}}/technical-data

-> so in your case:
https://app-gateway.prod.senec.dev/v1/senec/systems/253699/technical-data

or the other request that was reported as "failed" in the HA log...

my current assumption is, that "another" integration is messing up the shared ha websession - e.g. brute force deleting all cookies or other 'shit'... that an integrations should (IMHO) not do - or create/use an own/separate Websession...

The log you shared with me is full of other error messages... I just can recommend, that you disable all current integrations [except for the Senec's] (or at least the ones you installed in the past few weeks) - and then check/confirm, that the webapi-integration return to normal operation.

Thank you for looking over it.
I Think i will try it with a new install of Home Assistant but not now =)
