Installing ESPhome on GEEKMAGIC Smart Weather Clock (smalltv/pro)

ESPHome

Hi everyone, does anyone have a working code? I’m going in circles with the configuration of my SmallTV (green or blue motherboard). If someone could share a code that just displays “hello world,” I should be able to figure it out.

I fixed it, thanks to several other posts.

I created an ESPHome configuration for the low-end GeekMagic TV. It supports displaying three text pages with basic formatting and includes a notification service. The page rotation speed can be adjusted, and a specific page can also be set as fixed. It might not be completely bug-free, but it has been working well for me so far. I wrote it with a lot of help from Copilot. :wink:

I’ve made some updates to my ESPHome configuration for the low-end GeekMagic TV:
• Added support for five pages (up from three).
• Included a number input to set a max page for rotation.
• Implemented an error message if the sensor for the text isn’t set up in Home Assistant.
• Added more buttons and services to switch pages.
• Changed the font and font sizes.
• Improved the calculation for new lines, making it better and cleaner.
• Included a startup message since sensors from Home Assistant need to load before the first display.
• Added an action to update the display content whenever the sensor text value is updated in Home Assistant.
• Included a switch to activate/deactivate this last behavior.

These changes make the setup more flexible and user-friendly. Let me know what you think or if you encounter any issues!

I edit the code on the first post.

I’ve made some updates to my ESPHome configuration for the low-end GeekMagic TV:

  • Removed Large Font and restricted glyphs the because the fonts needs to much of the ram
  • Added two progress bars on top and bottom. The values are loaded from home assistant number sensors
  • added a display buzzer for alarming
  • changed the font rendering
  • added the status led light
  • changed the name schema for the home assistant sensors to make it easy to support more than one device
  • Removed unnecessary sensors and the logger to save RAM.
  • Added an option to create two columns on a page.
  • Enabled displaying a page initially in the bottom right corner.
  • Included the API key in the API configuration for potential REST API functionality (not thoroughly tested yet).
  • Updated the web server GUI to a newer, more user-friendly version.
  • Added sorting to the web server UI.
  • Settings are now saved between reboots.
  • Fixed issues with display and sensor updates.
  • Notifications are now queued for better handling.

I edit the code on the first post.

Not sure what the ULTRA version is, but it pops up from time to time [in the bundle-deals of Aliexpress]

Congratulations, Great job!!
I can show several HA sensors but I don’t understand how you can modify the size, position, color, etc.
