Has anyone got ESPHome working with this (Guition ESP32-S3 480*272) display?

This is the display I’m trying to get ESPHome onto.

So far, I’ve used this yaml. I wasn’t able to use the ESP Flasher tool. However, I was able to download the binary and flash it using Adafruit ESPTool.

esphome:
  name: experiment-thermostat
  friendly_name: Experiment thermostat

esp32:
  board: esp32-s3-devkitc-1
  variant: ESP32S3
  flash_size: 4MB

psram:
  mode: octal
  speed: 80MHz

# Enable logging
logger:

# Enable Home Assistant API
api:
  encryption:
    key: "..."

ota:
  - platform: esphome
    password: "..."

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Experiment-Thermostat"
    password: "..."

captive_portal:

web_server:

It does connect to wifi and the web server is working.

The next step is to try getting the display and touch working. From a review on the listing, I can see that the lcd controller is NV3041A and touch controller is GT911.

I see that people have gotten ESPHome working with GUITION 4” 480x480. I don’t see any mention of this device.

Why are you using third party flashing tools?

But more fundamentally I can’t find any support for the display chip in the esphome docs.

Does this help at all?

This is the first device I’ve had trouble with the ESPHome flash tool.

It gave an error about it not being an ESP 32.

I saw the Reddit post before posting this. I didn’t see anything that I was able to translate to ESPHome.

Unless you can find someone who has incorporated the driver for that graphics chip to esphome, you’ll have to port it yourself.
