How you will use the My Leviton app
If you are using or were previously using the Decora Smart Home app, you can now use the My Leviton app for maintenance of your Decora Smart 1st Generation (DH***) and 2nd Generation (D2***) HomeKit® devices. You DO NOT need to create or log into a My Leviton account.
Instead, you will select the "Use with HomeKit® Only" link on the My Leviton Login screen.
