Hello,
I am a novice in scripting.
Is there Anyone that can help me in reading out my doorbell status to link to object in KNX?
My Dorrbell is the 2N IP Verso and it has its own HTTP API (Testtool).
I need the status of the relay switch or the validation of the rfid card. Both would work.
My goal is following problem: If the relay switch status of the doorbell turns to 'true' then the knx group adresss (boolean) should write to 'true'.
I can start with "https://<ip-adress>/api/switch/status?switch=1" an request from the doorbell. The doorbell uses TLS and the type "digest" for https.
The response is:

Also enable Send Basic auth header in Remote services.
Yes, the point is the url works in a browser, then the LM works.
But i cannot make it works from 2n sending the http requests....
Good afternoon,
I am trying to set up this integration to know from the Logic Machine when there is an access attempt or an authorized access, and I’ve been communicating with 2N for several days. However, the conclusion they reach is that the Logic Machine redirects with a 302 and requests authentication. I’ve been running several tests and sending them the logs from the 2N device, but there’s no way to make it work.
I’m attaching a screenshot so you can see the configuration that I also sent to j.martinez. Did you manage to get it working?
2N is asking me to modify the Logic Machine API, but I know there must be something in the 2N access controller, because it should work with the same parameters as a normal POST.
The URL you see in the image is: http://192.168.2.205/login?ref=scada-remote
The text/plain is: m=json&r=grp&fn=write&alias=35/1/12&value=Prueba2N
I have tried several approaches — putting username, password and body in the URL; only body with username and password separately… but nothing works.

Hello DGrandes!!
The point is 2N devices didn't works with http request with headers where the user and password is sended...... 2N says they will includes headers to work with ASAP..... for that reason i used other way script they don't use passwords until we could do it in a safest way....

Thank you very much!
I’m going to try it.
Hi,
Activating “Send Basic auth header” on the reqbin.com page works the same as before, but from the 2N server it doesn’t work.
I also tried creating the file “write.lp” and placing it inside the public folder, accessing with "apps" user, but it doesn’t work even from reqbin.com, although it does respond with “200 OK” when I make the GET/POST request. With GET and POST it responds OK, but it doesn’t write anything to address 35/1/12.

This is the code:
Code:
<?
require('apps')
addr = getvar('addr') or ''
value = getvar('value') or ''
value = json.pdecode(value)
if type(value) ~= nil then
grp.write(addr, value)
end

Good afternoon,
That is not the issue. I’ve changed the script to analyze what the Logic Machine returns, and for some reason, it only receives the first variable within the string. If I put addr first, it receives addr, and if I put value first, it receive value (without "").
With this write.lp:
Code:
<?
require('apps')
addr = getvar('addr') or ''
value = getvar('value') or ''
> curl 'http://192.168.1.16/public/write.lp?addr=35/1/12&value=test'
Addr: 35/1/12
Value: test
Type: string
Value: test
> curl 'http://192.168.1.16/public/write.lp?value=test&addr=35/1/12'
Addr: 35/1/12
Value: test
Type: string
Value: test
Same thing when testing via browser.
If you call grp.write(addr, value) without decoding value as JSON then string values don't need to be escaped. But then if you send "false" the resulting value will be true because the input is not a boolean but a string (1/0 can be used instead). Sending complex values like date/time won't be possible as well.

Argument order does not matter:
Code:
> curl 'http://192.168.1.16/public/write.lp?addr=35/1/12&value=test'
Addr: 35/1/12
Value: test
Type: string
Value: test
> curl 'http://192.168.1.16/public/write.lp?value=test&addr=35/1/12'
Addr: 35/1/12
Value: test
Type: string
Value: test

The only way the string is accepted is like 3th option:
