Hello,
I have a problem with that when I go outside the home wifi (to which homey is connected) I can’t connect to homey via mobile data (phone)
Can you please advise me what to do with it?
Is your Homey reachable through the developer site: http://developer.athom.com/
Your homey is linked to your account.
Are you using the correct account?
Otherwise you should contact Athom support.
