I want to start using an Homey 1.0 that has been powered off for several years. He boots and connects to my wifi as he had been installed in the past. However I am unable to add him to the Homey app or to my account.
I tried using an old phone with the old homey app but that also did not work. Are there possibilities to do a forced upgrade or upgrade the firmware via USB so that I can start using it again?
Removing all the data is not a problem as everything needs to be set-up anyhow. Who can help me?
