Hi, I'm hoping someone can help me with this as its driving me potty!

Basically, as with the example on the forum using an Aviosys 9100, I use an axis M7014 connected to my sky box and pull images from it that are displayed. I've been trying to find a way for Demopad to know the current power status of the sky box. Because sky won'rt release API and I can't find how to do this using IP commands to the sky box (which I know it does because the most recent update of the box and sky+ app pulls data from the sky box including power status), I had a brainwave that I could poll the axis to see whether it is receiving video on the input the sky box is connected to and sure enough, there is a command that can be sent - http://<axisusername>:<axispassword>@<axisipaddress>/axis-cgi/videostatus.cgi?status=1 This is sent as <send data to a website> on page load. The response is Video 1 = video or Video 1 = no video and I know this works because this is displayed when I put http://<axisusername>:<axispassword>@<axisipaddress>/axis-cgi/videostatus.cgi?status=1 directly into a browser. I thought it would be straight forwards to set up a 2-way feedback matching <feedback matches specific data> with the date as Video 1 = video and then having to actions to set SkyPowerOn to ON and SkyPowerOff to OFF and the associated image is turned on. Equally, I had data as Video 1 = no video and then having to actions to set SkyPowerOn to OFF and SkyPowerOff to ON and the associated image is turned on. But it doesn't work

I've tried various device response terminators including \xOD, >, \r, \r\n etc etc and I can't get my head around regex.
Any help would really be appreciated

Thanks, Chris

The first thing is to be sure exactly what data comes back from the camera server - issue the HTTP GET request via Hercules & see the data (including the hex characters) that comes back. Common response terminators for html / xml data are \x0D, \x0A or worst case >

Quick reply as usual

I had tried using Hercules but had problems because I didn't seem to get the format right with what is sent. For example, I just tried;

You can try & get this working via [email protected] - the GET request would seem to be the way to go, but problems are probably being caused by the username/password. Here is a sample GET command for a similar device that requires very basic username/password authentication:

GET /Set.cmd?CMD=SetPower+P60=1 HTTP /1.0\x0D\x0AAuthorization: Basic YWRtaW46MTIzNDU2Nzg=\x0D\x0A\x0D\x0A

where the username/password is simply Base64 encoded

Thanks, I've emailed support.
I've just managed to successfully send a GET request via Hercules;

Connecting to 192.168.0.xx ...
Connected to 192.168.0.xx
GET /axis-cgi/videostatus.cgi?status=1 HTTP/1.1\x0D\x0AHTTP/1.1 200 OK

Video 1 = video
Connection closed

So there doesn't seem to be anything in the response apart from Video 1 = video, or do I have to include Content-Type etc?
Cheers
Chris

Hi
Sussed it!

I hadn't put the "\" in the response terminator, d'Oh!, so it works with \x0A as the response terminator and including it at the end of the data; Video 1 = video\x0A and Video 1 = no video\x0A

Works well and means I now have feedback for sky box power status, yay.
Thanks again for your help.
Cheers
Chris
