These changes are not firmware dependent. We have just released the beta for the new SmartApp model. Developers may start porting over their apps today and provide feedback. Groovy SmartApps do not have an end of life date and will continue to be supported for some time. Given we are still in the very early days of development I cannot even speculate as to when any switch over might happen.
You cannot do this with a local IP address but the new API’s allow much more control over your account than the old SmartApp Model.
- You can rename or update locations
- You can rename devices
- You can create and modify scenes and behaviors
- You can create edit and change modes
A developer could create a web interface that allows you to do most of the configuration/maintenance in a web browser.
