Okay I got the display displaying a test image, it is buggy and unstable though. Config below.
If anybody knows how to interact with touch interfaces to drive commands in home assistant it would be appreciated. I started looking at the lvgl stuff but that looks like its far too early in development to be useful.

I loaded your code and the screen is flickering all over the place. There must be something missing.
I tied a few different settings to match this code that is supposed to work but it didn’t help.
The touch screen pin is listed as GPIO4 here.
So I added this code. But that did not seem to do anything

);

Using 80MHz seems to get rid of the screen flickering.

After a few flashes/toying with settings I was able to get it to stop flickering too, at least with the RGB BW fill in Real.Problems post.
Tried adding image or graph display components and maybe I missed having to add an include or something for it?

has anyone had any luck with this device?
Yes, the display is supported in the current ESPHome release: RPI_DPI_RGB Display Driver — ESPHome
You realistically need to use LVGL, the ESPHome display drawing operations are too slow for the size of the screen, and LVGL is still in PR, but usable as an external component. See LVGL implementation for ESPHome by clydebarrow · Pull Request #6363 · esphome/esphome · GitHub

I just got mine from Amazon today. Going to use what everyone has posted as a starting point, and once I have a decent integration going, I’ll post up the code here and on my github

Hey folks,
just got mine as well. Any updates here on how to get it running?
Just got my ESP32-S3-Touch-LCD-7 in today – I’m able to get the clock display using the config above, now checking for 7" specific settings.
You need to define touch screen under section lvgl
Touchscreens:
Is there a way to lower the backlight or turn of the screen on the 4.3" model when inactive? My unit gets hot running 24/7

Hello, do you know if it is possible to connect multiple sensors to the board? I would like to connect one relay and one DHT sensor.
You can connect as many sensors as you like on the I2C bus, and you could use an I2C relay board as well. There no other GPIO pins available though.

Has anyone managed to change the brightness level on this device?
I’m missing something – I can detect touches on the screen but I’m not clear how to wire the touch events to lvgl buttons so they can be pressed.
Add a touchscreen key to the LVGL config. The display is auto-detected, but not touchscreen, it has to be specified explicitly.

Tips I learned for calling a service (such as turning on a light) from Home assistant using a button:
The “touchscreen” comments from Clyde and styphonthal above need to be included (see code snippet below) as this was not part of the clock code above.
The device has to be configured back in home assistant to allow it to make a service call (see note below from the esp lvgl cookbook - LVGL: Tips and Tricks — ESPHome ).
For weird compile failures relating to c library code and not YAML, make sure to “clean build files”.
