An alert from esp_screens_show_alert takes a `camera` (a camera.* or image.* entity): a Guition with firmware 0.2.57 shows that moment's picture across the top of the card, and a tap opens the camera full screen. A camera or image tile opens the same full-screen view, refreshed every four seconds at a steady pace. ESP Screen Manager fetches the snapshot with its own access, sizes it for the screen and serves a 24-bit BMP under a random, short-lived link on port 8098; the screen loads it with ESPHome's online_image and holds no Home Assistant token. BMP because ESPHome decodes it per chunk, where a full-screen JPEG held the loop 0.6 s. The CYD keeps its alerts without the picture and gets no camera tiles. The Guition also builds with ESPHome 2026.8+ again: backlight_fade.h derived from ESPHome's LEDC output, which 2026.8 made final, so the backlight now dims through ESPHome's own light transition. Tested on the bench boards and a local add-on on the Home Assistant Yellow; docs/TEST_RESULTS_0266.md. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

|
||
**A touch screen for every room that you lay out yourself, and manage from Home Assistant.**
|
||
|
||
**Why.** Your phone is in the other room and a tablet on the wall is expensive. A small ESP32 touch
|
||
panel costs a fraction of that, sits on a table or in a wall box, and is always at hand for the
|
||
lights, the heating or the vacuum.
|
||
|
||
**What.** Firmware for two affordable panels, the 2.8-inch CYD and the 4-inch Guition, with up to
|
||
twenty tiles over four pages: lights, climate, blinds and curtains, the vacuum, media, the weather,
|
||
history graphs, clocks and timers. An automation can put an alert on every screen when someone rings
|
||
the bell, and a Guition shows who is there with the doorbell camera's picture.
|
||
|
||
**How.** ESP Screen Manager is an app inside Home Assistant. It flashes a new screen over USB, updates
|
||
it over Wi-Fi and sends it your tiles. Changing a screen is pick, drag and **Save & send to screen**:
|
||
no reflash, no YAML to write, no blueprint, MQTT or token.

## Installing from Home Assistant
|
||
|
||
### Which screen
|
||
|
||
| Screen | Resolution | Display / touch |
|
||
| --- | --- | --- |
|
||
| CYD ESP32-2432S028 | 320 × 240 | ILI9341 / resistive XPT2046 |
|
||
| Guition ESP32-S3-4848S040, 4 inch | 480 × 480 | ST7701S RGB / capacitive GT911 |
|
||
|
||
Use these exact board variants: similar-looking product names can have different
|
||
controllers or connectors. Wallbox relays are not controlled.
|
||
The firmware and built-in CLI are tested with **ESPHome 2026.6.2**.
|
||
|
||
### Do I need ESPHome?
|
||
|
||
**You don't need to install the separate ESPHome Device Builder app.**
|
||
ESP Screen Manager already includes the ESPHome CLI and can build firmware itself,
|
||
install it via USB, and later update it wirelessly over OTA.
|
||
|
||
**You do need to pair the flashed screen via the ESPHome integration in HA.**
|
||
That pairing lives under **Settings → Devices & services**, not in the
|
||
App store. Add the discovered device there. If it doesn't appear automatically,
|
||
choose **Add integration → ESPHome** and enter the screen's IP address.
|
||
If asked for a key, use the `api.encryption.key` from your own device YAML,
|
||
and grant the device permission to perform Home Assistant actions.
|
||
|
||
| Component | Needed? | What for? |
|
||
| --- | --- | --- |
|
||
| ESP Screen Manager app | Yes, for this installation route | Installing firmware, managing tiles, and sending current data to the screen |
|
||
| ESPHome Device Builder app | No, optional | Alternative editor and firmware installer; the same CLI is already in ESP Screens |
|
||
| ESPHome integration in HA | Yes, pair every screen | The connection between Home Assistant and the physical screen |
|
||
|
||
So a fresh installation without ESPHome Device Builder also works. If there's
|
||
no ESPHome `secrets.yaml` yet, our wizard asks for Wi-Fi once and
|
||
stores it locally. Existing Wi-Fi secrets are reused. API and OTA keys
|
||
are generated per new screen and stay in that device's own profile.
|
||
|
||
### Step by step
|
||
|
||
For Home Assistant Container (Docker) without the App store, follow [ESP Screens with Docker](docs/DOCKER.md).
|
||
|
||
For Home Assistant OS with Apps/Add-ons on **aarch64 or amd64**:
|
||
|
||
1. Open the App store and add this repository:
|
||
`https://github.com/MaxGramser/homeassistant_espscreen`.
|
||
2. Install **ESP Screen Manager**, start the app, and open **ESP Screens**.
|
||
ESPHome Device Builder is optional: the ESPHome CLI is already in this app.
|
||
3. Connect the screen with a USB data cable to the **Home Assistant machine**
|
||
and choose **Settings → New screen**: CYD or Guition, a name, the USB port, and
|
||
**Install**. If Wi-Fi is missing from the ESPHome `secrets.yaml`, the window
|
||
asks for it once and ESP Screens only adds the missing lines. The profile
|
||
with unique API and OTA keys goes into the ESPHome folder; the build
|
||
and flash run in the same window (a first build takes a few minutes on a
|
||
Raspberry Pi). Each screen gets its own profile.
|
||
4. **CYD:** go through the calibration on the screen. **Guition:** uses GT911
|
||
without resistive calibration. Then pair the discovered ESPHome device in
|
||
**Settings → Devices & services** using the API key the window
|
||
shows after installation (copy button). Grant the device permission to
|
||
perform Home Assistant actions.
|
||
5. Select the screen in ESP Screens, choose your tiles, and click
|
||
**Save & send to screen**. Then test the physical controls.
|
||
|
||

||

|
||
<img src="docs/images/editor-tiles.png" width="59%" alt="Choosing tiles: every page in the screen preview, next to the entity picker with filters">
|
||
</p>
|
||
<p align="center"><sub>New screen (step 3) and choosing your tiles (step 5).</sub></p>
|
||
|
||
You can install new firmware later from **Settings → Firmware & USB → Wi-Fi / OTA**.
|
||
For an existing screen, always use the existing profile; creating a new
|
||
installation profile generates new keys.
|
||
|
||
