There are no significant new features in the initial move to 9.4 to simplify the switchover. Things like other colour depths will be added after that.

Thank you!
Thanks for the work - and confirming - I really was barking up the wrong tree on this one.
I think I am done with the final iteration of my library. You can now truly build a button on an ESP32 screen that controls a light in Home Assistant with one line of code.
This is what it looks like
packages:
button_1: !include
file: esphome-modular-lvgl-buttons/buttons/switch_button.yaml
vars:
uid: button_1
row: 0
column: 0
text: Light
icon: $mdi_lightbulb
entity_id: "switch.athom_smart_plug_v3_50ebc0_switch"
All you need after that is a simple LVGL grid to put the button on that looks like this.
lvgl:
pages:
- id: main_page
layout: 4x4
styles: page_style
<<: !include esphome-modular-lvgl-buttons/widgets/swipe_navigation.yaml
widgets:
The beauty of all this is the simplicity and flexibility. A novice can create their first screen and control a light in 20 seconds and an advanced programmer can mix a few simple prebuilt buttons on a screen with complicated ones that they design from scratch.

I guess i have to update my configuration 
This code doesnāt work - looks like the code was double pasted.
I couldnāt get the screen to display basic text even after fixing the typos, after several hours of debugging, I have a working version in ESPHome 2026.1.5. The key was adding reset_pin 33 to the display block.
I was able to get the Modular buttons Git repository working with some effort.

Are you using this test code here?
It works and give you a few test buttons. I tested this code recently with 2026.1.5 and it works well.
That demo file also has the Home Assistant Voice Assistant enabled and working.
The code in post #4 in this thread doesnāt work:
The modular buttons code works ok; my Git pull missed a couple of files for some reason - took a while to troubleshoot.
I want to make some improvements to the modular buttons package - Iāll post on Git; number one is modular cover control for the blinds in my house.
I just updated esphome-modular-lvgl-buttons recently. So refresh you git pull to get the latest.
I am making Voice Assistant modular as well so you can include it or not with one line of code.
That would be amazing! Send me a pull request and Iāll add it to esphome-modular-lvgl-buttons
Will do!
Messing around with the voice assistant now. The file fails to validate when including the voice assistant - āmy_microphone not definedā. esp32_microphone is defined in the hardware file, but I canāt find my_microphone defined anywhere.
It validates fine with this, but not far along enough to determine if it works:
Thanks, I just updated that. I fixed it for all six esp32-p4 screens that I supportā¦

2026.2.0 adds full support for this screen. I just updates my demo code for it to use the released driver for the screen.

Has anyone had success configuring portrait mode for this device? In portrait mode, it fits perfectly inside the cut-out for the Nutone intercom system Iām removing; but has to be raised above the wall in landscape mode.
After rotating the config 90 degrees, it still thinks the x is 1024 and the y is 600. The touch is stretched / displaced, and the screen display is also stretched / displaced.

But the performance is terrible! mipi_sdi displays do not have hardware rotation so this is implemented in software. Screen is very laggy and unresponsive in this mode.
Unfortunately the best way to do screen rotation would be to use the 2D hardware graphics capabilities of the P4 but there is no ESPHome drive for this yet.
Thatās really funny. That is exactly what I am using the screen for as well! Iām going to see if I can power it using the old wires from the intercom. They go to the basement so I can attach 12v to them.

Itās very simple / easy to do - here are some pics. Happy to share the 3D printed parts.
The main Nutone panel has 120v power and a transformer. I connected a 120v to 12v DC power supply, then 12v to 5v USB at the remote station. Iāll do a standalone post once all running.
Iām planning a 10" display on the main station, and 7" display on the remote stations. Using landscape mode isnāt terrible - gives space to mount a speaker and sensors. Iām planning a mmWave sensor and temperature / humidity sensor to start.
Looks great! If you put the screen the way you have it now you have room for a speaker.
What case is that?
Self designed / printed; still a work in progress. Iām planning to use the standard speaker included in the waveshare box.
Nice, I am working on a lot of projects like this. Check out my button library if you have not already. I have a lot of prebuilt widgets for a screen like this. I will have a media player soon.
That board and other P4 based boards should include all sorts of cool stuff in the future including video playback.
A hardware mod you might consider is a brightness sensor. I have a part of my library that trys to get the screen brightness so itās not annoying but I really need to have it respond to room light level.
lux sensors are cheap. Thanks.
I looked through the button library - really appreciate your work. Iām starting with the mechanicals and basic room controls to start.
I would like to do an audio intercom eventually also. I donāt use cameras inside my house, but audio only would be nice.
