Trigger HTTP call with @ sign in the url

• Issue of the topic: trying to trigger a HTTP call

Hi everybody,

I’m getting back on track with OpenHAB. I’m trying to link a Doorbird to my OH2.4.
I’ve searched the posts in this community but everything is related to pre 2.x and not working correctly.

I have a “doorbird.items”

Switch doorbird {http=“>[*:GET:http://192.168.1.x/bha-api/open-door.cgi?r=xxxxxx@1?&http-user=xxxxx0001&http-password=yyyyyyy]”}

and a “default.sitemap”

sitemap default label=“My First Sitemap”
{ Switch item=doorbird label=“Doorbird Switch”
}

And this shows the sitemap with a switch.
But, when I push the button, OH does trigger the API but the API returns

{
"BHA": {
"RETURNCODE": "0"
 }

This means authentication is ok but nothing has happened.
I’m using a Doorbird I/O controller, so to trigger the external relays that are linked to the doorbird I have to add “?r=xxxxxx@1” to my call.
When I leave this part out of my call, the API returns

{
“BHA”: {
“RETURNCODE”: “1”
}

So for some reason, the “?r=xxxxxx@1” isn’t sent correctly to the doorbird API. If I do “?r=pepepexx@1” it also returns “0”. So it’s a kind of 404 not found error.

It works in a browser, so I’m sure the url works.
I have the same issue when I try to curl to my doorbird, so I have the idea that something is wrong with the encoding. Does anybody have the same issue?

Try to replace the @ with %40 in your URL (URL encoding).

@imbrechtsjurgen

?r=xxxxxx@1?&http-user=xxxxx0001&http-password=yyyyyyy

In addition to what bbock wrote, there should not be a second question mark in the query string:

?r=xxxxxx%401&http-user=xxxxx0001&http-password=yyyyyyy

You should be able to do this with the ipcamera binding as I added the ability to open doors via one of the channels. It may have been an alarm channel I re-used. By using the ipcamera binding you should be able to stream the video to multiple devices as normally the cameras are limited to a single stream.

IpCamera: New IP Camera Binding

This binding is now merged into openHAB 2.5.9 and newer. See below for more details on what each brand of camera has working as often choosing the right camera will save you from needing to purchase an extra video server (both the cost to purchase the server, plus the ongoing electricity costs) to process the video feeds. Features for Generic cameras with only RTSP (no snapshot url): Snapshots (jpg) can be created from RTSP with low CPU overhead but requires non stop network traffic to keep …

Also there is also a new Doorbird binding here…

Doorbird video doorbell binding

Important Update: The binding was merged into to the openHAB distribution today, Oct 17. It should be available in a snapshot release after build 1728, as well as the next milestone release. We made several changes to the binding throughout the review process: The restart and sipHangup channels were removed. They were replaced by the thing actions restart() and sipHangup() that can be called from within rules. There’s an example in the README. The doorbell channel was redefined to be a s…

@bbock Already tried the %40 encoding, didn’t work.
But the question mark that @namraccr saw was the issue.
Thanks for the reply, the problem is fixed now.

My items file now contains this.
Switch doorbirdvisitorgate {http=">[*:GET:http://192.168.1.10/bha-api/open-door.cgi?r=xxxxxxx@3&http-user=uuuuuuuuuu&http-password=pppppppppp]"}

Going to try the suggestions from @matt1
