STUMPED! Onvif - PTZ service call - Errors!

Rural_assist · May 25, 2019, 3:36pm

Hello.
I’ve integrated an onvif camera. Image works well!
After writing this script:

ptz_tilt_up:
  sequence:
    - service: camera.onvif_ptz
      entity_id: 'camera.onvif'
      data:
        tilt: 'UP'
ptz_tilt_down:
  sequence:
    - service: camera.onvif_ptz
      entity_id: 'camera.onvif'
      data:
        tilt: 'DOWN'
ptz_pan_left:
  sequence:
    - service: camera.onvif_ptz
      entity_id: 'camera.onvif'
      data:
        pan: 'LEFT'
ptz_pan_right:
  sequence:
    - service: camera.onvif_ptz
      entity_id: 'camera.onvif'
      data:
        pan: 'RIGHT'
ptz_zoom_in:
  sequence:
    - service: camera.onvif_ptz
      entity_id: 'camera.onvif'
      data:
        zoom: 'ZOOM_IN'
ptz_zoom_out:
  sequence:
    - service: camera.onvif_ptz
      entity_id: 'camera.onvif'
      data:
        zoom: 'ZOOM_OUT'

when calling the script I get this error:

Error executing service <ServiceCall script.ptz_tilt_down (c:f7ce3c0440f14f45a295ecc64937e622)>

Any ideas?

It would be great to indicate what camera you’re using.
Have a read

Will take a look at your link. Thank you!

AhmadK · May 26, 2019, 12:41pm

CGI commands work for my camera so it might help you too.
and if you modify your script according to the second link, it should do the job.
don’t know how the camera.onvif_ptz suppose to work though, but I’m my case it says “PTZ is not supported” in HA log despite the camera being fully controllable via various apps/its web fronted.

Rural_assist · May 26, 2019, 2:25pm

Unfortunately. Those CGI commands didnt work for this device.

I’ve uploaded some screenshots of the TideTech Camera web interface. Which basically looks like a generic camera companies buy to logo up and sell!

There are options in the PTZ settings to change the type of PTZ communication. I’m hoping these shots may help someone point me in the right direction to get HASSIO to work it. The camera is set on Palco-D to work with the apps I’m using so far.

100% has nothing to do with that camera. I have a Foscam camera and it has ONVIF. I altered the script to that entity and it does the same.

As stated in the HA manual

If you remove any entity reference then the “camera.onvif_ptz” service will target all.

Targeting entities FOSCAM and The ONVIF CAM or none at all give the original error message.

Failed to call service camera/onvif_ptz. Cannot be called from within the event loop

Not quite sure how to go forward. Anyone got any ideas?

AhmadK · May 26, 2019, 6:57pm

open a new issue on GitHub?

Rural_assist · May 26, 2019, 7:04pm

Thats an idea mate. But I think I’ll just keep using an app to move the PTZ.

Also looking at flashing another system (on the side) with one of the other open source systems like OpenHab to see whats achievable on them. I’m finding quite a few un-solveable glitches on HASSIO.

AhmadK · May 26, 2019, 8:41pm

yeah, that’s always down to the balance of pros and cons…

signaleleven · June 25, 2019, 7:52pm

I’m having the same problem.
Looks like it has something to do with async calls.

mclaudiopt · July 4, 2019, 3:46pm

HELLO to all
anyone has made this work?
thanks

Rural_assist · July 4, 2019, 9:40pm

Nope! TBH it sounds like they should really un-publish the feature…

mclaudiopt · July 6, 2019, 8:44pm

i get this error:
Falha ao chamar o serviço camera/onvif_ptz . Cannot be called from within the event loop

manthoR · August 24, 2019, 6:35am

Same here.
Any news ?

REALogics · August 25, 2019, 12:45am

I have FOSCAM FI9928P ONVIF PTZ Camera and get the same results… “Cannot be called from within the event loop”. I am able to PTZ with “ONVIF Device Manager”.

Has anyone made progress on this?

manthoR · August 25, 2019, 9:03am

I think full onvif support is one of the key feature that lacks to HA…
Onvifer and onvif manager easily rotate my cameras…

But HA…

REALogics · August 31, 2019, 12:57am

My ONVIF camera PTZ does not work. I am not a HA Python coder. Can someone answer why this directory/file does not exist in HA… and should it? It appears wsdl is the method for accessing PTZ service.

/usr/local/lib/python3.7/site-packages/onvif/wsdl/

This is the file being fetched around line 148 in ONVIF/camera.py:

"{}/wsdl/".format(os.path.dirname(onvif.__file__)),

I am using HA 0.92.2. I am trying to understand the code in order to fix it.
