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

ESPHome

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.

Nice work. There seems to be a million types of these little Chinese screens out there. And a lot of people getting them all working with ESPHome!

Make sure you reference the screen by it’s label on the back that way others can help you more easily. This seems to be a “Guition JC4827W543R” if you reference it that way more people will be able to help you and people searching for how to get their screen working can find this post.

Let me know if you get this screen working and I’ll add it to my esphome modular lvgl buttons system.
