Running! Complex research but elegant & simple implementation 
Ich kann nur gratulieren 
Bei mir ist Problem, meine Englische Sprache ist noch schlimmer als Deutsche. Und zum Webserver, ist möglich, dass OZW Version 6 unterschiedliche Menutree und Datapoint Nummer als Version 10 hat. Aber das gibt man sehr leicht per OZW Webschnistelle und Webapi feststellen. Und wenn möchten Sie, irgendwo in Computer habe ich noch Firmware 7 und 8 für Update. Schreiben Sie mir email, und könnte ich es schicken. Viele Grüsse aus Tschechien. Vaclav

Now I am looking into the details. There are three different outside temperatures
-
current outside temperaturemeasured via input B9: used for frost protection:P#8700andID? -
mixed outside temperaturecalculated with 1. and the building isolation constantP#6110: used for heating:P#8704andID1183 -
outside temperature low-passfilter: used for switching between sommer and winter mode:P#8703andID1182
See details in the manual on page 205.
I am not able to find the ID for 1. current outside temperature. Any idea how to get it?
Can you find it in the administration interface?
Yes, that is where I was searching. I clicked through all menus and could not find it. Here is the response based on @venca.kratky very cool idea to get the IDs:

sorry - everything in German 
… now my complete list of all IDs I can access on my system:
- OZW672-WebAPI-Response.txt and
- all html-pages webAPI.html.
Here you can do a simple text search and find the ID easier. Hence, I think the IDs are different for different systems.
You can upgrade to V11 directly. You just need to do Factory update (*.fmwz) to upgrade the web server to the latest firmware version instead of firmware upgrade.
@stefferber did you upgrade eventually? Also on V6 but planning to upgrade to V11 this weekend.
Do anyone know if there is a physical room thermostat that can interface directlly with the webserver? I don’t have the wires pulled in the house to connect a thermostat and thought this could be a good way to go through the internal network.
thanks
edit: as an alternative, could you confirm I can push the “internal measured temperature” back to the main thermostat through HAS and the ozw672?
You might want to have a look on Brötje’s IDA. But better to ask a dealer/installer.
thanks.
I ordered my device yesterday. Will probably start by simply sending back the measured room temperature so that the boiler can adjust its consumption.
Do you mean that you just ordered an OZW? You should have had a look on BSB-LAN as well.
My system is running fine. Therefore, I will not consider an upgrade 
Strange behavior in OZW672.
I have OZW672.1 with revision 10 firmware. The only controller is the heat pump controller RVS61.843F/147
We can see that rootID for this is
When you make certain changes in the controller you MAY have to do “Generate Device Web Pages”
Documents will tell you when you have to do the generation for changes to be effective.
But generation deletes ALL the Ids and creates new ones. As a result HA can no more find data point since their Id’s have been changed.
I guess this can be easily demonstrated by generating OZW itself.
RootID now:
After Generation it is
Now question is whether there is a way to use API to address data points in a more robust way which could survive Device Webpage Generation ?
Could someone be so kind as to PM me API Reference (preferably version10) so I could try to solve this?
Does someone know a workaround for this?
Hello,
Could someone please provide me with the pdf for the API, in English if possible? I am also working in trying to expose data and got to a dead end using the OZW 775 Web Server. I read online about it and contacted support but so far I have not yet received any information. I checked this whole thread and it gave some really good points as to where to start but I am not really sure as the interface is a bit different as to where to access the web api from so I can manage to make calls and get the information from all the data points.
Thanks in advance!
Kind regards,
Adriana
Hello,
Would you be so kind as to provide me with the PDF of the API Interface as I am having some issues trying to enable the web api on an OZW Web Server 775 and I am unable to. It would be really appreciated if you could share it as it is so hard to find it online.
Thank you very much in advance.
Kind regards,
Adriana
Hello,
I am currently working on trying to access the for the OZW Web Server 775 and I am having issues trying to find the exact setup for it. Would you be so kind as to send me the specific web a[o documentation that you currently have as it can be very helpful although the model is a bit different.
Thank you very much in advance.
Kind regards,
Adriana
there once was an Openhab binding for this, which never made it to production, only beta.
If I understood well, the way that binding handled this issue was by using the names instead of ID’s.
Not 100% sure but think the binding on a regular basis made a download of all the IDs and names of these and used this table to lookup the ID. So a regeneration would change IDs but once the lookup table is refreshed the binding will automatically use new ID as the name hasn’t changed.
I’m planning to update my HA instance (after more than 1 year without update 
) but I struggle with the rest integration which I use to access my Siemens OZW672 like described in this topic.
After updating, I have rest sensors that became periodicaly unavailable with is really annoying.
It seems to be due to the update of the restful integration which has been updated last year and modify the way it address the connection (at least what I understand…)
With the old rest integration there was a limit on the number of connections that the integration would make since it was sync. The async version has no such limitation and may be overloading the device.
It happens because I have many sensors related to rest integration (>35) updating very often.
The workaround would be to manage to use the rest integration to create multiple sensors using the same endpoint like mentionned there : RESTful - Home Assistant.
It would reduce the number of request to 1 each time and not overload the rest integration.
But I don’t think it is possible since each sensor need his own dedicated endpoint, and not all sensors are returned inside the same JSON.
Can someone help me with this?
thank you
Hi @inuites
I also tried to integrate a Siemens OZW772 (which uses the same JSON API) and had the same issue.
Did you already find a solution for integrating multiple rest sensors?
I’m happy to provide more details or discuss possible solutions…
Thank you!
You can solve this with nodered making no more simultaneous request but sequenced .
It will work at 100% 
.
Remember to make token request in nodered too to ensure other request work. (Saving it in a local nodered variable)
