This is an extremely fast little screen. It seems like a good one for ESPHome. It has dual noise canceling microphones for Voice Assistant.
We now have a working config here
I haven’t spotted any post - looks like a serious bit of hardware.
If all you need is a 7 inch display with adequate resolution for 7 inch, this one has tons of support:
But if you can get the one you posted running that would be interesting…
That’s a nice screen but it does not have built in dimming for the backlight LED. This is a requirement for me. There are a lot of hardware mods to get it working.
There is a good thread on this form for that screen already
Let’s keep this thread about the Waveshare ESP32-P4-WIFI6-Touch-LCD-7B only so as not to create confusion.
The Discord team got it working!!

Hi @andrew_NH Andrew i looked at your github and i tried several times to get your code up and running i always got the error message “NFO Package configuration completed successfully
INFO Package configuration completed successfully
INFO Successfully compiled program.

ERROR ESP requests password, but no password given!” but i did not set any password for ota but beside that there is an ota password in my secrets.yaml. so my question is where is the part where your configuration is asking for an ota password? Thanks in advance for an hint 
Nothing in my repo has a password set. But you can set one if you want. It is not required.
yes, i got it working more or less but it seems that the waveshare ESP 32 Touch LCD 7B (without P4 and wifi 6) in general a bit buggy. By the way, is there any documantatation how your modules are working and how to bring them up to an display to like the light buttons, the weather? I’ve tried but got nothing to work.
Yeah sure everything you need to know on how to set it all up is here in the readme file.
Start with the demo that matches your screen.
The code is very well documented so you can see the lines that control the buttons. Just change them to match a light you have in your HA setup.
example just change the entity_id to match a switch you have. That’s it.
# Button 2 - Standard light button with state updates
- button: !include
file: esphome-modular-lvgl-buttons/buttons/switch_button.yaml
vars:
uid: button_2
height: $button_height_single
text: Button 2
icon: $mdi_lightbulb
entity_id: "switch.athom_smart_plug_v3_50ebc0_switch"

I think over all the waveshare-esp32-s3-touch-lcd-7B is a very nice screen. It’s a bit slow to do swipes but other then that it works great!

Hey, thank you so much for your response. I’ve now managed to get the display running, and the page with the buttons is also showing up.
What I haven’t quite figured out yet is how to integrate individual modules, for example for the weather. Do I need to add a new page in the main configuration under LVGL to display the weather data and weather icons? From what I understand, the pages are added in the main configuration under LVGL & Pages. I just don’t have any idea how I need to insert the individual weather YAML, or what the LVGL code should look like. Would it be possible to provide the code for the weather module? That way, I could understand the structure based on the example and adapt it to my configuration – that would really help me a lot. I’m unfortunately not yet deep enough into LVGL and ESP Home to understand it right away.
I know these are a lot of questions, but I hope you can give me a little nudge in the right direction.
When compiling the firmware, there were a few deprecation warnings regarding the select option.

My code is quite flexible you can make a new page with the weather or add it to an existing page.
I have examples of both here
This one shows both the weather and a tide clock on the same screen.
Turning the Display Completely Off
I was annoyed with the display remaining on/dim when the backlight is turned off. Unfortunately, turning the display on/off by adjusting the voltage of the LDO caused the HSYNC/VSYNC (and other parameters) to be incorrect when turned back on.
The ESPHome mipi_dsi component does not implement the on/off commands for the display, and the handles necessary to send the MIPI DCS commands via lambdas are protected. So I created a class to access the mipi_dsi protected members by creating it in the same namespace and using inheritance.
This has been working for me without issue, so I thought I would share what I have so far.
Prerequisites: This requires a configured
mipi_dsidisplay in your ESPHome configuration.

Sorry for the delay to answere but i was a bit busy because of my job.
Really thank you more then a million times. That pushed me in the right direction and i got it working. Again thanks a lot for your support and your hard work which you have done for the esphome-modular-lvgl-buttons repo.
That is really nice. Do you want to add a feature request to ESPHome? I think this would be a great upgrade.
Awesome - got it working thanks to this; I changed the board to variant, the same as I did with the first gen Waveshare touch 7 inch.
Has anyone got the display working with RGB rather than RGB565? I’m not sure how this works - but looking at Add WAVESHARE-ESP32-P4-WIFI6-TOUCH-LCD-7B driver the init sequence seems to be a lot smaller than the others and I wondered if that could be preventing it from using RGB.
I did some digging and found the EK79007 datasheet from the EK79007 readme which has a decent description of how to use the init sequence.
Probably barking up the wrong tree and I’ve missed something obvious (not the first time lol)
A big gotcha for me was that the image: component doesn’t inherit the LVGLs endiness.
Edit: The espressif page for the device I believe is: waveshare/esp32_p4_wifi6_touch_lcd_7b • v1.0.2 • ESP Component Registry but @andrew_NH to confirm this is the exact version etc.
Second Edit: I’ve successfully built and flashed the LVGL demo from the waveshare github repo to see if that reveals anything.
Thanks,
Charlie
Just an update - I was completely barking up the wrong tree with this.
24bit mode is only supported in lvgl@9 - and the settings for using the display are:
pixel_mode: 24bit
color_depth: 24
Thanks,
Charlie
By any chance, did anyone manage to make the audio work?
I got to a point where I hear something, but the sound is heavily distorted.
…and no mic.
What I have seen from the schematics is that the codec and mic are on the same i2c bus.
Found a repo that extends the audio module of esphome with pipelines and, according to the docs… It /should/ work… But did not get that far.
32bit should work with LVGL 8.4 (I played with it before on other devices), but ESPHome’s mipi_dsp driver only supports 16 or 24 at the moment.

Have you tried the audio configuration from here?
I just tried the Media Player from Home Assistant using those settings and it seemed to work well. The mic was also receiving data, but I haven’t done much testing with it yet.
RGB888 is new for lvgl 9: Changes in master (v9 development) · Issue #4011 · lvgl/lvgl · GitHub
Also from https://forum.lvgl.io/t/color-depth-24-is-deprecated/10618/2:
Actually a 24 bit color depth was never truly supported. Earlier it meant (X)RGB8888.
However, in v9 native rendering to RGB888 format will be supported.
Not sure if it made it into [lvgl] Migrate to library v9.4.0 by clydebarrow · Pull Request #12312 · esphome/esphome · GitHub or not.
Also - doing a quick scan, there’s 32bit for one display driver for lvgl.
