Implementing esp32 7" Display ESP32-8048S070 - need Help

[Grieche]

Hello everyone,
i found a blog where a 7" TFT powered by a esp32 was implemented into Home Assistant to show … HA stuff.
I thought that it is a good idea to use this big screen and improve my smart mirror with it. (LINK to he current one)
My first idea is to use espHome to and just reuse my code but unfortunatly I have no idea how to properly get it running in espHome.
The Hardware:

• esp32-s3
• Display chip: EK9716
• The whole system in alibaba: LINK (There is also a link to arduino.io libraries and schematics etc.)

The code (14.05.2023 doesnt work for now):

esphome:
  name: "smart-mirror"
  friendly_name: "smart-mirror"
  on_boot:
    priority: 199
    then:
      - light.turn_on: back_light
  project:
    name: "jb.Smartmirrorwithesp32"
    version: "0.4.0"

My first issue is the:

display:
  - platform:
    model:

Sadly i couldnt find any espHome support for the display chip EK9716. Maybe iam blind or there is really nothing.
I tried just du reuse the ili model because it was somewhere mentioned in the arduino libraries from the manufacturer.
The Backlight is working proberly but there is nothing displayed. I dont know if it is a platform/model issue or i dont use the correct pins.

Here is a schematic of the layout:

Note: Top left is the esp32 layout, top right is the display connection layout.

Has here somone an idea how to figure out if i use the correct pins or use the correct display componend?
Or maybe it is all not supported by espHome and i have to find a espHome independet solution.

A big thanks in advance if somone could help me!

[zoogara (Daryl)]

Unfortunately you won’t get that going with ESPHome, not only because of no driver support, but also because of memory limitations.

ESPHome is quite memory hungry. To get an ILI9488 running an 480x320 resolution, you need to use an ESP32 with a fair amount of PSRAM. Your display has a resolution of 800x480 - many times that of the ILI9488.

That doesn’t mean you can’t integrate with ESPHome. Just write some C++ code and use MQTT to communicate with HA, just as the person in the blog you linked has done.

[nickrout]

These work with openhasp and it has great home assistant integration.

https://openhasp.haswitchplate.com/0.7.0/hardware/sunton/esp32-8048s0xx/

[zoogara (Daryl)]

Ah yes - good thinking. I used it with a couple of my ILI9488s before ESPHome supported them.

[Grieche]

Thank you for your answers.
Not the answers that i wanted to hear but they help me to continue with a solution.

Regarding the ili9488: Is there a good system combined with an esp32 that you would recommend?
Iam looking for a big as possible display that is usable with an esp32 and easy to implement into my HA environment.

[nickrout]

You have such a system. It just requires you to use openhasp rather than esphome.

[Grieche]

Thanks for the confidence. The next days iam going to dive into openhasp

[fsadak (Fikret Sadak)]

But OpenHASP supports only one font. Is there any way to use several font with OpenHASP?

Best Regards…

[nickrout]

@fsadak

But OpenHASP supports only one font

Nonsense. Fonts - openHASP

I am using Arial Bold on one at present.

[andrew_NH (Andrew)]

openHASP does not work with this screen. They have a build for the Sunton ESP32-8048S070C this seems to be a slightly different screen then the Sunton ESP32-8048S070 ESP32-S3 even though the part number is only different by one letter “C”.

The people over at Tasmota seem to have the ESP32-8048S070 working and they have detailed info on how they got it working. I don’t know enough about codding to translate their code to ESPHome.

Assistance needed in adding Sunton ESP32-8048S070 ESP32-S3 7inch Display support

Can somebody do this translation?

[andrew_NH (Andrew)]

This works!

Hi,
thank you for the late answer. I actually dove into openHasp and manged to build my smart Mirror with the Sunton Display.
If you are interested, look into my post where I explain my code:

Smart Mirror with HA, openHASP a 7" Display powered by esp32

Hello everybody, I just want to show you my (just another) smart mirror project. Look here for my first iteration: LINK The goals: I wanted to build energy-saving smart mirror witch is showing data of my HA System and is completely in open software. Material that I used: ESP32-8048S070 A 7inch LCD display powered by an esp32 without touch one sided mirror glas 4mm thickness, coatet with chrome with 8% light transmission Display housing is an own 3D print USB-C Cable Frame is a special bui…

But Iam looking forward to the possibility to use it also with espHome. Thank you for the example.
Kind regards.

[andrew_NH (Andrew)]

That looks great! Did you use some kind of tool to build the “Star Trek” style display?

[Grieche]

Nope, it was manual coding of rectangles and cycles in openHASP. See the code that i posted in my “guide”.

[doubleU (willem)]

I’ve been looking at this display, would it be possible to run kind of a lightweight webbrowser on esp32 (and/or offload rendering to host running ha)

[nickrout]

I don’t know of a browser that runs on esp32. Are the existing systems not working for you?

[andrew_NH (Andrew)]

You can make some really neat displays with the new LVGL code. You can display gauges and other types of Homeassistant output to make very nice info screens.
