@Spl4sh, Look at the calendar.get_events
action in Home Assistant to pull more than the next event from the calendar.
Thank you for your response. What changes should I make, please? Iām not sure I fully understand the article
Right now, youāre showing just the next event using the default calendar entity, which only exposes one upcoming event at a time. To display the next 3 events, youāll need to take a slightly different approach using a built-in Home Assistant service called calendar.get_events
.
This service lets you fetch a list of upcoming events (e.g. next 3) within a time range, like the next 7 days. The idea is to call this service regularly, store the top 3 events in some helper entities like input_text, and then read those values from your ESPHome display.
Hereās a general breakdown of the steps youād need to follow:
- Create a script in Home Assistant that calls the calendar.get_events service and saves the results (like event title and time) into helper entities. These can be input_text entities that act as placeholders for each event.
- Set up a way to regularly update them. You can automate this by running the script every 15 minutes or so, using a simple time-based automation.
- Update your ESPHome display so it reads from the three new input_text entities, instead of just one calendar sensor.
This approach gives you a lot of flexibility, you can format the event details however you want (date/time, summary, description) and decide how often to update them.
Hello!
Iām experiencing an issue with my Waveshare 7.5" e-ink display connected to an ESP32 Waveshare board mentioned here.
For a while I had zero issue, but tonight I ran quite a few refreshes for debug purpose (roughly a 100) and adding more stuff to it.
When displaying minimal content (text over half of the screen), the blacks appear deep and proper. However, as I add more content to the screen, the blacks become increasingly washed out and gray. Interestingly, during the refresh cycle when the screen flickers, I can see proper deep blacks momentarily. I would think to either a power distribution limitation in the e-ink display when handling larger amounts of black content, or potentially a physical connection issue with the ribbon cable (which I double checked). Iāve checked my configuration but havenāt been able to resolve the problem. Also this morning having the same text displayed on 2/3rd of the screen didnāt seem to be an issue, but tonight, its washed out. If I go back to half of the screen (top part or bottom, makes no difference), deep blacks are back.
Iāve got the āv3 stickerā screen.

Has anyone experienced similar issues or have suggestions for improving black levels when displaying more content? Have I messed up my screen?
