Custom interface design
Customization of the screen is implemented in test mode. You can now convert and upload any image through the device's control panel and adjust the "widgets" position.
Upload is available at http://[Device IP address]/upload/image (via the menu "Custom design" -> "Upload custom image"). After uploading set your saved filename in "Custom design" - "Preset" to use it instead of default UI
Advanced widget display options ("Show hidden options")
- -f - clear the background area under widget position
- -m - mini version of the widget (available for Temperature & Humidity widgets)
- -hpa - [pressure widget] pressure in hPa (default - mmHg - мм.рт.ст)
To check if the display supports 2-bit graphics (images with 4 shades of gray), refer to the display comparison table
When using ESP8266 we are limited by a small amount of RAM and to display 2-bit picture when switching modes of operation (initially for example 15kb was already allocated for 1-bit buffer) may require rebooting the device (performed automatically) to allocate the necessary block of RAM
To avoid regular reboots you need to use images of the same bit rate or a microcontroller with a large amount of RAM ESP32
Default interface (4.2' and 1.5')
Custom interface examples
This functionality is still in beta testing, and the format for storing widget placement on the device may still change. If widget positions reset after a firmware update, you just need to re-upload the original JSON design file.
