I have an http command that works in my browser to change a camera position.
I created a rule in RM so a door contact is open them action is to send this HTTP command to position the camera. Logs show RM is triggered, but no cam movement.
Any ideas?
You can send from terminal and it works?
Click on the rule, click on the gear icon and click on events. Just double check that the event is being sent correctly to the rule. You want to see something like this:
|RM||Tool Closet is now True|2019-03-25 04:03:11.677 PM EDT|
|RM||Zone 024 - Tool Closet Door contact open|2019-03-25 04:03:11.534 PM EDT|You can also try Dan's HTTP switch to troubleshoot.

But the http command is not moving the camera, whereas in the browser the command works fine.
Permission needed
This command works in browser- no cam login required.
Do you mean some other permission?
What headers are you sending in your get?
On one of my custom devices I had to properly define "contentType" and "requestContentType" for an "asynchttpPost" in order to get it to work... maybe there is some more info you need to send along?
Yeah it was Camera login, I meant
Like I said, the http call works fine using a browser. My cam moves to a preset just fine.
If you are talking about something else HE needs, I have no clue what that would be. I assumed HE simply pushes the http call onto the network. This stuff used to work fine with my Vera controller. What would HE be doing differently?
Yes and that's because the browser sends certain additional information with it's http get request. Stuff like "USER-AGENT" etc.. what I'm suggesting is there is a difference between what the browser is sending and what your call is - maybe it's missing some of this information that the cam's webserver expects.
Have you tried using the postman utility? You could independently confirm the http call and isolate the issue to HE.
Did you try it from a virtual switch device page? I had issues with my HTTP Get so I removed the try response part of code since I don't think my HTTP was providing a response. I will try and go back and figure out the right way later but for now it is working for me.
def on() {
if (logEnable) log.debug "Sending on GET request to [${settings.onURI}]"
sendEvent(name: "switch", value: "on", isStateChange: true)
// try {
httpGet(settings.onURI){ resp ->
// if (resp.success) {
// sendEvent(name: "switch", value: "on", isStateChange: true)
// }
if (logEnable)
if (resp.data) log.debug "${resp.data}"
}
// } catch (Exception e) {
// log.warn "Call to on failed: ${e.message}"
// }
}I tried Dans test switch and it logged

It looks to me like RM is sending correctly. Correct me if I'm wrong.
Sorry, I don't know how to use this app.
So try setting the content type to: "text/html" in your parameters in the http get call maybe?
"application/x-www-form-urlencoded" is usually associated with form data..
It's not all that hard to figure out postman, you don't need to sign up or anything and it will let you do a get/post/put with whatever parameters you need. Very handy and worth learning if you are going to be doing http/REST call development etc.
I appreciate all your help and suggestions. I did figure out what is wrong. Auth fails. and the reason is that FW change in the cam.
Some bonehead dev with Amcrest has decided that it will lock out any ability to auto login "for security". The
Before my http code worked fine. Today it shows me a login screen first. So my cam must have been already logged in before and my code worked.
So heads up! Amcrest cams are amazing. BUT no more http control! Amcrest said they will not change this decision.
That sucks to hear!! You might be able to automate with something like Headless Chrome and puppeteer or selenium but it would take some messing around with..
Thanks for the suggest but I'm done screwing with this. I put in a ticket to Amcrest and see what they say but I am not expecting anything.
There isn't a network ACL in place is there? Both my LaView cameras and iSpy server allow me to setup ACLs for what devices can access them . . . (trying to think of anything)
I double-checked mine just to make sure it wasn't something in one of the recent releases that broke the http get from Rule Machine . . . mine are still working fine.
