I am using UART2 (GPIO 43 and 44) and have set the toggle switch to UART2. However, even after disabling the log component output or turning off the ESP Console, the sensor still does not work on the UART2 interface. Has anyone been able to get the sensor working on UART2?
I made my own HMI design for this device.
It’s currently mounted on the wall in my garage.
All the code is shared.
For the past couple of weeks, I’ve been cooking up a HMI for my garage. The motivator was to cover the area that was previously occupied by a very old alarm keypad I removed the panel a couple weeks ago. And you know, provide cool features to my home automation setup while doing so!
First attempt at using ESPHome’s LVGL component.
Quick video of it in action:

So far it’s working OK. A couple of bugs and glitches I hope to get fixed i…

I wanted to reduce the copy and pasting that needs to be done to use this display, so I created an ESPHome package you can use. Hope it helps someone! GitHub - inytar/waveshare-esp32-s3-touch-lcd-7-esphome: ESPHome package to use with waveshare-esp32-s3-touch-lcd-7
Hi, could someone possibly help me? I have Waveshare 7" and 4.3" displays, and I’m trying to add an XL9535 2-channel relay using the YAML code below.
I’ve tested the code and relays on an ESP32 WROOM using SDA: 21 and SCL: 22, and everything works fine. So I connected it to both my 7" and 4.3" screens, changing to SDA: 8 and SCL: 9. For the most part, it works.
The problem I have is that I cannot control Relay 1 - Relay 2 works. I’ve tried changing the pin number from 0–7 and 10–17, but nothing works. I’ve also tried changing inverted: false to true, but there’s no change.
Any help would be greatly appreciated!

Hello Derham, can you please tell me the RS485 pin details in ESP32-S3-Touch-LCD-7? i just need to interface the QR scanner through the RS485 so please guide me the tx and rx then if need rts pin.

Hi leev, sorry i haven’t used the RS485 connections yet. Perhaps someone else can chip in with the answer?
Leev, the following has been working for me on the ESP32-S3-Touch-LCD-7.
uart:

tx_pin: GPIO16
rx_pin: GPIO15
baud_rate: 9600

I really need som help with my ESP32 S3 Waveshare 7" touch display. It stoped working for a couple of month ago. I tried to reflashed with my latest yaml config but the screen is black. I also bought a new screen and that one is also black no matter what yaml configuration I load up. Now I tried with a configuration that worked before - also black screen but I can se some kind of background light. The code that worked before but now gives me a black screen is this: GitHub - runevad/waveshare-esp32-s3-7inch: ESPHome with Waveshare esp32-s3 7inch tablet

Is the code compiling OK? Because if I remember correctly i needed to add this under esp32:
cpu_frequency: 240MHz
before it wouldn’t compile, then every time it is updated it gives a black screen. I then unplug it and it restarts fine. If I restart using the restart button it doesn’t boot. A quick unplug and plug in and its fine again. I gave up trying to find out why.

I am no expert in this yaml esphome stuff though so I may be very wrong.

thanks. That fixed it lol. I also added a wire so I can control the backlight brightness.
