Install & use
Let AI help you install
Connect the device and give AI the detection results together with this firmware information.
1
Confirm the device and connect USB
USB chip information cannot distinguish monochrome from four-color screens. Confirm the model first.
Connect USB and detect the device
Read the chip and capacity first, so AI needs fewer follow-up questions.
Detection may restart the device into download mode. It does not flash firmware; you still need to confirm the display model.
Not detected yet. You can also copy the task first and ask AI to help connect.
2
Give the installation task to AI
Codex on your computer can install dependencies and run programs locally.
What AI will do next
Check compatibility → Prepare firmware and a full backup → Assist with local installation → Verify first run
After copying, start a new chat in Codex on your computer and paste the task.

Only project information and the device details selected here are included. Network addresses, accounts and keys are configured locally during installation.

After installation, check this
The device shows the expected JazzTrix interface and continues to update correctly.
Ask AI to report the installation location, verification results and how to start again. Continue in the same conversation if something goes wrong.

NOTE4 / NOTE4C · ESP32-S3 / 16 MB Flash · ESP-IDF 6.0 · USB-C data cable · Wi-Fi
Back up and build the application firmware
Preserve a full Flash backup and verify the existing partition layout and recovery path. No GitHub Releases package is currently available. Build the ESP32-S3 application in firmware with ESP-IDF 6.0 following the README. The author specifies application-only flashing at 0x20000, preserving the existing bootloader and partition table. This is not a full image for 0x0 and must not be applied to an unverified partition layout.
Pair a phone and configure Wi-Fi
Hold the round button for about 2 seconds or double-tap, join JazzTrix-Setup, open http://192.168.4.1 and enter the pairing code. Configure home Wi-Fi, weather location, time zone and radio. Built-in cities or manual coordinates work for offline setup.
Confirm the panel model and test operation
The project includes NOTE4 / NOTE4C panel detection and manual selection. Confirm the detected model; monochrome panels map red/yellow elements to black. Test weather, radio buttons and volume, then add a brew via phone NFC. Nine interface languages are available, while haiku remain English.

Frequently asked questions
Is this a local-push plugin?
This is standalone community firmware that replaces the device system. It does not run through the official local-push SDK or ZECTRIX Cloud Open API. Radio, online place search and data updates need their corresponding network services. The source is MIT-licensed, retaining notices for Karim, Tomasz Fiedoruk and third-party components.
What do the image and review cover?
NOTE4C project photo from the author’s repository; not evidence of our own hardware testing. Source, dual-model implementation and author images reviewed; build, flashing and hardware not independently tested
