Connect your PlantWave
This updates your PlantWave to firmware …. It takes about 4 minutes and keeps all your settings.
Plug your PlantWave into this computer with a USB data cable and press the button. Chrome will show a small window; choose PlantWave Serial and press Connect.
Good to know
My computer asked to let Chrome use Bluetooth
That prompt comes from Chrome itself, not this page: Chrome lists Bluetooth serial ports alongside USB ones, and macOS asks before it may look. You can safely choose Don't Allow; updating over USB works either way.
The update failed partway
It is safe to retry: every step is verified before your PlantWave restarts. Unplug the device, plug it back in, and go through the steps again.
