Let me first thank for the great plan44 gateway with all its possibiities! Just great!

Goal: I would like to import digitalSTROM sensor values to plan44. I would like to do so because one can easily perform calculations in plan44. For instance in plan44 one can compare a humidity in a room against a humidity outside and then open an airvent depending on the outcome of the comparison.

The idea in short is as follows:
(a) I plan to access the digitalSTROM-Server through the JSON API. This seems to work.
(b) This JSON API is then called in p44Script to make the values known to plan44. Here I have a problem.

Subsequently, I comment on how I performed the two steps up to the point where I am failing.
(a) Acessing the digitalSTROM-Server:
(This works sommothly. Yet, I am describing the whole process here. Just to be complete)
I have already access to the digitalSTROM-Server through the JSON API. Towards this end, I have created a token based digitalSTROM login as described in the "digitalSTROM System Interfaces" manual v1.7, chapter 6. The token is then used to call a session token. The session token can then be used to retrieve information by JSON calls.
For getting access to the DSS I then have to perform the two steps
i) Login with my permanent token. So for instance I can type in my browser
https://192.168.178.21:8080/json/system/loginApplication?loginToken=[my permanent token]
The browser will respond by delivering a session token:
result
token "e18d99e5bcf7abcdf32a9d399779919b5263a725fd66dd47412ba8008f1b560a"
ok true
ii) Subsequently I can use this session token to perform JSON API calls.

The digitalSTROM JSON nomenclauture has been described in the manual “digitalSTROM-Server JSON”. I am now using the following command to retrive the sensor values
HTTP GET /json/apartment/getSensorValues
In my case this translates into typing in a command of the form
https://192.168.178.21:8080/json/zone/getSensorValues?id=17&groupID=1&token=[session token]
where id=17 is the number of the room
As a response I get:
result
id 17
name "Garage"
values
0
TemperatureValue 15.05
TemperatureValueTime "2022-11-06T14:14:32.471Z"
1
HumidityValue 79.525
HumidityValueTime "2022-11-06T14:10:20.032Z"
ok true
So, all the desired values seem to be accessible. All that needs to be done is to import them by a p44Script.

(b) Calling the digitalSTROM JSON API with a p44Script
Here, the problems start!
I am using the REPL shell to test the p44Script. My calls of the form
var a='https://192.168.178.21:8080/json/system/loginApplication?loginToken=[private token]'
geturl(a,30)

Just lead to error messages of the form:
// *** Error: SSL connection error (HttpComm::civetwebError[20000])

I now wonder how to properly type in the geturl command. I am somehow puzzled. As this seems to work for sites like the "https://api.openweathermap.org/..." - an example under https://plan44.ch/p44-techdocs/custdevexamples/ . But somehow this does not work for digitalSTROM. What is wrong here?

Kind regards
