sibbl / hass-kindle-screensaver Goto Github PK

There's already a Docker container but ideally, this application should be easy to integrate into any Hass.io instance.

The HA connection details and access token should be automatically requested from the supervisor.

However, it might be necessary to improve some performance as well as it might be possible that Puppeteer might not run very well on supported Hass.io devices like the Raspberry Pi.

First off, this is awesome. Thanks so much for writing it, publishing it, and letting others use it.

I built a lovelace dashboard that included the OpenWeatherMap integration. I was putting my thermostats and the weather forecast onto the dashboard that would go to my kindle. I added the MOMENT_TIMEZONE environment variable (set to EST5EDT for me). But I was still getting UTC/London time. To help me troubleshoot, and to help me know when the image was last captured, I added a time_date card to the lovelace dashboard. I was seeing the correct local time (e.g., 15:32) in the time/date card, but I was seeing UTC/London time in the openweather card. The forecast was right (i.e., it's forecasting for my city), it's just that the times were wrong (where you see "9:00 PM" and cloudy, my image would show of "9:00 PM"). The attached image shows what it looks like, except that it's correct. (Still haven't gotten around to beautifying it...)

I needed to add TZ=EST5EDT to my docker-compose.yaml file when I deployed it. After adding that environment variable, the images come as you see them.

Interestingly enough, if I visit the URL for the dashboard using a web browser on my laptop, all the dates and times came out correctly. It was only the hass-kindle-screensaver that was rendering the forecast times incorrectly.

So you might want to update your README file to mention the TZ variable. I suspect others will run into something similar.

Currently unfortunately the °C unit is hard coded. This should be read from the HA entity and displayed accordingly.

A new config option KINDLE_MODEL should be introduced, which should allow various values like kindle4, k4, pw or paperwhite.

Depending on this value, the screen size should be set to the correct resolution.

The screensaver worked fine for me for a long time, but it stopped after I updated Home Assistant and now I get the following error:
