OH3 - SOAP connection for Saxonian "Hochwasserinformations- und Managementsystem (HWIMS)"

hello together

I am trying to integrate the flood warning system of the state of Saxony into openhab, I have the free access and the interface description (see below), I could also use a local PHP server. But I just can’t get any further - I just don’t know anything about SOAP :slight_smile:

With the first idea, to go via HTTP binding, I can’t get any further, do you have a better idea?

Finally, I would like to implement an alarm that triggers upstream from a certain level. A nice to have is the display of the water levels in the graph. I just need a number that is updated every 15 minutes.

THANKS :slight_smile:

What is your preferred programming/scripting language ?
E.g. for python, perl, php there are SOAP client libraries available.
You need to build request structures like shown in the example to get back the responses like in the example.
I personally would use the exec binding or a cron entry which is triggered every 15 minutes.
The returned value then can be stored via REST API or in a file.

as far as I see, the HWIMS uses SOAP, which is a pain in the a$$ to use.
you could try to use something like here in that python:

not sure, if MOWAS also has those information, but I import the MOWAS emergency broadcasts like this with openHAB:
