Preview of Blink mini thumbnail

Question

Preview of Blink mini thumbnail

sungilaka opened this issue 2 years ago · comments

Describe the bug
When trying to preview the thumbnail of a blink mini in a picture card, no image is shown and errors are generated.

To Reproduce
Steps to reproduce the behavior:

Add a picture card with blink mini thumbnail to your dashboard

Expected behavior
Show the last picture of the camera.

Home Assistant version (if applicable):
Home Assistant 2022.4.0b3

blinkpy version (not needed if filling out Home Assistant version):
0.19.0

Log Output/Additional Information
I was hoping to be able to show images of the camera in my dashboard (as I already know, that i live view is not possible?)

I already updated Home Assistant, because of all the reports of a similar bug, but in my personal case (maybe I did anything wrong, as it never worked before and I just started with Home Assistant) it does not work.

Error when looking at the dashboard with the preview card:

Sometimes, but not when clicking on the button to trigger the camera, another error appears:

seems a bit like this?

Kevin Fronczak · Answer 1 · Sun Apr 03 2022 21:40:19 GMT+0800 (China Standard Time)

Are you positive you're running the April beta of home-assistant? This was confirmed to be fixed by multiple users with the 0.19.0 library and the thumbnail url you have should not even be possible anymore #551

sungilaka · Answer 2 · Sun Apr 03 2022 21:48:06 GMT+0800 (China Standard Time)

Wow, you are fast :D
I´m sure with the HomeAssisstant version, but not sure if it uses a old version of blinkpy...

Kevin Fronczak · Answer 3 · Sun Apr 03 2022 21:53:06 GMT+0800 (China Standard Time)

Ha not all the time, I just happen to be on right now.

Yeah that version of HA is using the latest of home assistant. My only two guesses would be to simply try and force a refresh via the service (blink.blink_update I believe) or to try just re-installing blink. You shouldn't have to do that, but I really don't know why this bug would persist otherwise.

On blink_update there is a warning:

And still the same error with camera.py

I already removed the blink integration and re-installed it, but it also did not help.

Same problem but in 2022.3.8 I already removed the blink integration and re-installed it, but it also did not help.
My camera is Blink Outdoor.

I have 0.19.0 version installed.

Good news, when updating to version 2022.4 everything works again. Thank you very much

@sungilaka - I have a Mini camera and it looks like I have the same problem: no picture updating in home-assistant. However, when I try the library as standalone, I can download the image just fine. So can you try the following:

Start blinkpy via command line (view readme for quick start guide)
Report the value of blink.cameras[<cameraname>].thumbnail
Run the command blink.cameras[<cameraname>].image_to_file('/some/path/for/image.jpg')
See if it saved an image and you can open it.

Running through those steps on my end results in a successful image and Home-Assistant should be doing the same thing, but I don't see any thumbnail in the GUI. I just want to confirm we see the same issues.

sungilaka · Answer 9 · Sun Apr 10 2022 13:18:44 GMT+0800 (China Standard Time)

It seems to be working as standalone.

The thumbnail functions gives the following URL: https://rest-e006.immedia-semi.com/api/v3/media/accounts/14978/networks/14585/catalina/14041/thumbnail/thumbnail.jpg?ts=1648990353&ext=

And the image_to_file function save a image of the camera which can be viewed.
Even taking new images is working there.

sungilaka · Answer 10 · Sat May 07 2022 22:15:19 GMT+0800 (China Standard Time)

@fronzbot Did you already find some time to have a look on it? I updated to Home Assistant Core 2022.5.0b5 in the meantime, as I saw, that the fix for the issue you mentioned was merged to this version. As far as I can say, it did not fix my problem.

Is there any way I can help you? I have the mini outdoor cam and also the error on the latest version.

For anyone else wandering in here looking for a solution, use the blink app on your device to force a refresh of the captured image used for a camera (the [ ] button). Then, in Home Assistant, go to Developer Tools -> Services and type in "blink" and select the line for blink.blink_update and the use the [Call Service] button. That should pull the latest images from Blink. This eliminated the missing thumbnail error for me.

Well, triggering an update of the camera thumbnail works (I think with errors, but it works). The main problem might be, that homeassistant can´t load the image. When I trigger "camera.snapshot" for my blink mini outdoor (and maybe the outdoor is the problem?), the following error appears:
