Flash a Homey wall panel

Plug the panel into this computer with the cable that came with it and press Install. It takes about a minute, and it is the only time a panel ever needs a cable — after this, updates come from Homey over Wi-Fi.

This browser cannot talk to USB devices. Use Chrome or Edge on a computer — phones and tablets cannot do this. Flashing needs a secure connection (https).

Then what?

  1. Install Wear OS Controller on your Homey if it is not there yet: that is where a panel gets its cards, and where the pairing code below comes from. Panels need version 1.34 or newer, so for now take the test version.
  2. The panel restarts and shows Wi-Fi setup, with a network name and an eight-digit password on screen.
  3. Join that network with a phone. The setup page opens by itself; otherwise go to 192.168.4.1.
  4. Pick your network, type its password, and paste the pairing code from Homey (Wear OS Controller → app settings → Copy pairing code).
  5. Add the panel as a device in Homey, then open Repair on it to choose the cards it shows.

Nothing here is sent anywhere: the image is downloaded from this page and written to the board by your browser. The panel never learns your Wi-Fi password from Homey — you type it into the panel itself.
