Steps
Use Chrome or Edge on a computer
(phones and Firefox/Safari can't talk to USB devices).
Connect the scale with a USB-C cable.
Click Connect & Install, pick the scale's port from the list,
and confirm. Flashing takes about a minute.
When it's done, the scale creates its own Wi-Fi network for first-time setup
— connect to it and enter your home Wi-Fi, then calibrate with a known weight.
See the scale guide.
No port in the list? Try a different USB-C cable (some are charge-only),
or hold the scale's BOOT button while plugging it in.
