valumi 1.1

A crypto price ticker for the Waveshare 1.47" ESP32-C6 boards: live prices and charts from OKX, configured via device-served web pages. Firmware supports both touch and non-touch board versions.

Install

Easiest: in your browser. Plug the board into a computer with a USB-C data cable and open the valumi web installer in Chrome or Edge. Click Install valumi, pick the board's port, and wait about a minute.

Or by hand, with esptool and the valumi-1.1.bin below:

pip install esptool
esptool.py --chip esp32c6 write_flash 0x0 valumi-1.1.bin

If the board's port doesn't show up, try another cable (many carry power only), or hold BOOT while plugging it in.

Then

The ticker shows a QR code for its own Wi-Fi hotspot, VALUMI-XXXX. Join it with your phone, tap Sign in to network (or turn mobile data off and open http://4.3.2.1 after connecting), and add your Wi-Fi. The ticker joins your network and shows its address and panel password; afterwards the panel is at http://valumi.local.

Updating

A ticker already running valumi updates from its own panel: Device → Firmware update, with the same valumi-1.1.bin. That keeps all settings. (Installing over USB starts fresh.)

Highlights

• Up to 15 coins, checked with the exchange as you add them; drag to reorder
• 1D / 7D / 30D charts: closing prices, a smooth line through each swing's highs and lows, or closes over a low-high band

• Touch board: swipe between coins, hold a finger to pause, picture follows the board's orientation
• Several Wi-Fi networks in order of preference; setup hotspot with QR code; firmware updates with automatic rollback; settings backup and restore
• Over-the-air firmware updates
