I reset the homey pro 2026 to factory. It is breathing blue. I click on the setup process link in that article and I get the authorization error above.
I iPhone app just says 'Cannot connect to Homey Pro 2026.
Seems to be a dead link. Anyway, you’ll need to perform the setup process in the Homey app on your phone (not via a link in the support article). Make sure Bluetooth is enabled on your phone.
I see you’ve already solved this, but for anyone else reading: you can’t connect to that device from your phone’s Bluetooth settings. Only the Homey mobile app can connect to Homey Pro
