I cannot login with my username and password. I’m sure they are correct and I successfully activated my account.

At the moment only 16 unique smartphones/tablets can have access to the Out-of-Home functionality with 1 Out-of-Home account. This limitation is introduced to increase the security of the Out-of-Home functionality.

Currently it’s not possible to remove the access for certain smartphone from your Out-of-Home account in order to have access with another unique smartphone. To clear the list of allowed smartphones/tablets, please remove your user account and perform a factory reset on your Daikin LAN adapter.
