Fridge Dashboard

Firmware flasher for the reTerminal E1002

A live render of the dashboard, as the panel will show it

Before you click

  1. Use Chrome or Edge on the Mac (Safari can't talk to USB serial).
  2. Plug the reTerminal into the Mac with a data USB-C cable, not a charge-only one.
  3. Click Connect, pick the port that appears (usually usbmodem or usbserial), then Install.
  4. If no port shows up: hold the device's BOOT button, tap RESET, release BOOT, then retry.

This replaces the firmware Seeed shipped. Seeed's Firmware Hub can put it back any time.

Step 2 — live dashboard (v0.4)

Joins your home Wi-Fi, pulls a fresh dashboard on the schedule (every 15 min 6:30–9 am, hourly till 3, every 30 min till 9:30 pm), and sleeps in between. Any button = refresh now.

This browser can't flash over USB. Open this page in Chrome. Web Serial needs an https page.

Step 1 — static test image (v0.1)

No Wi-Fi; draws one baked-in frame. Useful for checking the panel.

What happens next

With the live firmware: the device reboots, joins Wi-Fi, asks what's flying over the house, has the dashboard rendered, and draws it — about 20–30 seconds from boot to picture. Then it sleeps until its next slot. If Wi-Fi fails it says so on screen and retries in 10 minutes.

Unplugging the USB cable afterwards is fine; it runs on battery between refreshes (plan on charging every couple of weeks at this schedule).
