Confirm the four-color device and back up
This project supports NOTE4C only. Back up the complete Flash and record the existing partition layout.
Choose an installation method
For first installation, use the project's matching complete merged image. App-only updates apply only when the partition layout is compatible. This site has not checked the current Release and installable files, and does not offer flashing here.
Initialize time and Wi-Fi
Follow the project's first-boot flow to join its hotspot and configure home Wi-Fi and time. Afterwards, use the buttons to change messages or reopen settings.
Information organized · Release version and installation await review. Generating a task does not send it or run an installation automatically.
Frequently asked questions
Is this the same as the monochrome weather plugin?
No. This is firmware installed on NOTE4C. A computer-based weather plugin that retains the factory firmware is a different workflow.
Does it need a constant internet connection after installation?
According to the listed documentation, the RTC keeps time offline and the device refreshes and synchronizes time on a schedule. Check the selected version for exact behavior.
