You’re great Dennis! With the first one I resolved my problem with the driver (actually, that one contains its own driver, I guess that helps, and it’s only posted yesterday?). I can now see the custom Dashboard I have in homeassistant, so the buttons and the style is exactly the same whichever screen I use.
Here is the code:
esphome:
name: mini-screen
friendly_name: Mini Screen
# Boot Sequence to set backlight and make a noise to test those functions
on_boot:
then:
# Turn down the backlight
- delay: 1000ms
- light.turn_on:
id: display_backlight
brightness: 50%
- delay: 500ms
- switch.turn_on: board_buzzer
- delay: 1000ms
- switch.turn_off: board_buzzer
