Is it possible to substitute an existing Z-Wave device with an other comparable Z-Wave device? I have two dimmer switches which I am not happy with, they do not dim low enough. Both of these dimmers are scene controlled and are also controlled by several Luup snippets. I would like to be able to remove the old dimmer switch and add a new dimmer switch using the old dimmers Device ID; this would/should allow all my scenes and code to function as if nothing changed.
No. Sorry.
The issue is the node and device ID number. You cannot control the assignment of these numbers at inclusion. Their later use in scenes is stored in a proprietary database, so changing things there is also not an option.
Your best option is to include the new switch, add it to the desired scenes, then exclude the old switch.
