One HA plugin doesn't get updated #31

Closed vdbrink closed 2 years ago

vdbrink commented 2 years ago

I got it all working and everything got updated exept one plugin, https://github.com/aex351/home-assistant-neerslag-app He keeps the data from the first initial call. I set my browser to 800x600 but there it all looks correct. Can this be related to puppeteer cache? Or maybe the headless browser in combination with this plugin?

Hi vdbrink, thanks for creating an issue for this.

Just to make sure: other components on the page update properly, so it's really just this one component?

If so, I unfortunately don't have a solution for this. It doesn't look like the plugin caches something in the browser's localStorage and it doesn't introduce custom ways to fetch the data. It relies on the HA APIs and doesn't seem to do anything weird on a first glance at the code.

Since the rendering opens a new page each time and then closes it, it should also fetch the data from HA each time.

One thing you could try would be to set RENDERING_DELAY=30000 (= 30s) and check if it helps to give the browser page and thus also the lovelace card more time to settle before the screenshot is taken.

Let me know if this helps! Otherwise it will be necessary to run the Node.js server locally with the DEBUG flag to be able to debug the page with the browser's dev tools.

Hi @sibbl,

Thanks for your quick response. I had to put the delay already to 30 seconds otherwise the image didn't get generated so that's not the case.

I removed this docker container and recreated it so I can't have any cache issues. Now I see one hour offset in the graph.

After I added the environment property TZ=Europe/Amsterdam it works!!

Can you add it to the list of your defined environment variables?
