I tried with openhasp, but it seems like I’m still at first love, esphome. how to apply for support? maybe I’ll be lucky and support will come in the next update.

I also bought a WT32-sc01 Plus. I got it working with GitHub - strange-v/ha_deck: Config-driven Home Assistant dashboard (built on top of ESPHome). I like that it is a ESPHome component and the integration into Home Assistant works well. The configuration of the UI components is a little bit limited and I had some issues with hiding components, but it works.
I tried openhasp yesterday. The UI is much more configurable, but the JSON is very complicated and I can’t add additional components or sensors. Also it’s more effort to get data from Home Assistant to openhasp than with ESPHome.
I would love to see native support for the display and touch screen in ESPHome! Especially I would like to test this component LVGL implementation for ESPHome by clydebarrow · Pull Request #6363 · esphome/esphome · GitHub

Hi there, I have added support for the WT32-SC01 Plus module to TFT_eSPI and created a pull request (3423). While it is being reviewed you can give it a spin using my fork.

hi many thanks for this !!! will have a try when back from hollidays 
I have also a wt32-sc01 plus - ZX3D50CE08S-V15 230208 and I am also trying to get it running with esphome firmware and the LVGL Graphics component.
On Aug 6 2024 [lvgl] Final stage by clydebarrow · Pull Request #7184 · esphome/esphome · GitHub was merged: The implementation of LVGL in ESPHome in a native way - configured with YAML. A big step for touch displays!
Unfortunatly, Implement i80 bus for ili9xxx displays by clydebarrow · Pull Request #6537 · esphome/esphome · GitHub, very relevent for the display driver ST7796UI with the MCU8080 8Bit bus, was closed (not merged) on Aug 7 2024. I will keep following @clydebarrow for any new PR.
Futhermore, dkalliv PR, Add support for WT32-SC01 Plus module by dkalliv · Pull Request #3423 · Bodmer/TFT_eSPI · GitHub, is stil open (Review required). Is there any way I can use it?
However, someone called bearpawmaxim mentioned he got his wt32-sc01 plus working with LVGL. He left a snipped of his esphome config yml in where he included the PR #6537. I tried to use his config snipped for my own config, but I am missing parts.
Below my config. I used the esp32-s3-devkitc-1 board and the esp-idf framework. Can anyone confirm whether that is correct?
I didn’t include the FT6336U touch screen component and the lvgl Graphics component. Has anyone an example?

Why did I got this warning?
Set --flash_size 32MB is larger than the available flash size of 16MB.
It was recommanded in the wt32-sc01 plus documentation to use this option.
Powering up the wt32-sc01 plus after flashing didn’t do anything.
In can see in the log file that esp32-s3 keeps booting over and over again:

Does anyone have an idea why the esp32-s3 keeps boot looping and how I can fix this?
Did you get the 4MB or the 16MB model?
I got the esp32-s3-wrover-n16r2, 16MB SPI flash and 2MB PSRAM.
16MB is not big enough for 32MB

You have me figured out, @nickrout! Indeed, I had not understood that the flash size should match the SPI flash size, but now it sound very logical 
Flashing it with --flash_size 16MB worked out well:
./esptool.py --port /dev/ttyACM0 write_flash --flash_mode dio --flash_size 16MB 0x0 '/home/tedsluis/Downloads/wt32-sc01-plus.factory (2).bin'

Does your example (I recklessly… lent 
thanks for that ) survive a reset of the plate / sc01 plus? For some reason, your example works brilliantly after flashing but after rebooting, the screen stays dark.
EDIT:
For some reason, it does now survive a restart - i honestly have no idea, why. Same cable / powersupply, tried it many times. After doing some more flashes but only adding RBG-light, I do not know, why it works now.
@Hubert34567 , I had a similar strange, but different, experience. After the first time flashing, streaks kept appearing on the screen, as you can see in the picture, even after a power cycle. After flashing a second time with the same configuration, I had no more stripes. I have no idea why this happened.
I am running into an other issue with my wt32-sc01 plus. With a new extended lvgl configuration, my build became larger than 2MB and I run into this error:
Linking .pioenvs/wt32-sc01-plus/ota_data_initial.bin

I understand that I can overcome this problem by using a custom_partitions.csv. I came to this partition table:
# Name, Type, SubType, Offset, Size
nvs, data, nvs, 0x9000, 0x5000
otadata, data, ota, 0xe000, 0x2000

app1, app, ota_1, 0x410000, 0x400000
spiffs, data, spiffs, 0x810000, 0x200000
And I added this custom_partitions.csv to my esphome config:
esphome:

A new build with this configuration ends with this error:

Why does the error message indicate that the flash size is 4MB, while I specified a 16MB flash size? What is going wrong here and how can I fix it?
But you didn’t tell ESPHome that. Try just setting flash_size: in your config and forget about the custom partitioning.
Thanks for your pointer, @clydebarrow! I thought it was enough by specifying the flash size with:
esphome:
platformio_options:
board_build.flash_size: 16MB
esp32:
framework:
type: esp-idf
sdkconfig_options:
CONFIG_ESPTOOLPY_FLASHSIZE_16MB: y
I have now added this:
esp32:
flash_size: 16MB
Here is my full esphome config: /config/esphome/wt32-sc01-plus.yaml
Although now I managed to build a firmware, at the end it appears that OTA partition is too small and this firmware can only be flashed with USB:

It seems to be in a boot loop.
Does anyone have an idea what is going on?
How can I fix this?
Yes, when the partitioning is changed you need to flash over USB - once that is done you will be able to update via OTA.
I posted a working config earlier in this topic - I’d suggest you start with that. Flash the known working config first (over USB) then change the flash size and reflash. Start adding your code in one thing at a time, then if something fails you will know what to look at.

And I’m still using it 
My config, if it can be helpful for you, can be found here (and everything in battery-controller folder)

Nice work. Is that the plastic screen protector still on the front

Are you supposed to remove them?
