hass-addon does not render png about hass-lovelace-kindle-screensaver HOT 11 CLOSED

The best issues are those which resolve themselves 😁

Thanks for the feedback. Only the battery webhook environment variable was added, but maybe also a new hassio base image was used when building - which might include bug fixes I don't know about.

Feel free to continue this thread if you encounter the issue in the future again!

Hi @Pattern91,

thanks for your kind words!

Failed to render TimeoutError: Navigation timeout of 50000 ms exceeded

It seems that the machine is not able to open the page and finish rendering it within 50s. The value is already quite high, so it could be possible that your machine is too slow for running this project.

You can try to increase the RENDERING_TIMEOUT to something above 60000 milliseconds (maybe try it in 10s steps). Please also adapt CRON_JOB accordingly, as it will try to render a new image every minute - which might fail if the rendering takes longer than 1 min. The cron job value */2 * * * * will trigger the rendering of a new image every 2 min instead of 1 min.

I hope you can get it running! I'll keep in mind to make this a bit more easy to a) figure out and b) configure the values in the Hass.io addon.

Hi @sibbl ,

thanks for you fast reply. I already have the cron job value so that in only runs every 10 minutes. I just want to move my installation from the docker container to the ha-addon. In the container the rendering was about 2-5 seconds.

The system is running on a RPi 3b+

from hass-lovelace-kindle-screensaver.

Just for my understanding: the docker container was also running on the same device before, or do you want to move it from another system?

from hass-lovelace-kindle-screensaver.

yes, the docker container was running on the same device using portainer. I stopped the container and installed the ha-addon instead and copied the values from the old configuration.

Very strange, indeed. Unfortunately I'm not that familiar with the Hassio addon development details, so I don't know what's technically different to running the container without the addon base image.

The only thing I could think of is that the IP might not be accessable from the docker instance due to security constraints of the HA addon sandbox - we don't request the permission to run in the host network. Even though the IP leads to the same device, the docker network is a bit different and probably the request ends up being sent to your router, which sends it back to the device. But the addon doesn't know that...

Do you have a public domain set up, which you could try instead of the local IP and give it another try?

from hass-lovelace-kindle-screensaver.

unfortunately i don't have a public domain. Is there another way instead of using the local ip-address of the pi?

i can access the used lovelace dashboard from other devices in my network.

Maybe this compose file helps, as I also use docker on a Pi 3b:

@814d3 thanks for the file. You also have troubles or do you say it's working for you and just wanted to provide a working docker compose file? Because if I understood the issue above correctly, the docker compose way is also working fine - but that there are problems when moving to the Hass.io solution on the exactly same device. Which obviously should work as the resources were there before.

@sibbl Did you change anything in your new version 1.0.5? It is somehow working after the update! Big thanks"
