Is it possible to dim smart bulbs (when switch is in Smart Mode) at the switch itself? Or is it only triggered as ‘scenes’ for up/down buttons
Right now it is only with scenes triggered. I believe the inovelli team has stated that you would need matter bindings for this to work. Matter bindings are in the matter spec but are not supported by any of the matter hubs at the present time. So if one of the matter hub vendors adds support for matter bindings the switch firmware could be updated to allow it to be bound to the smart light and you would have the dimming control you are looking for from the switch.
You can with “convert to shortcuts” automations but it’s still clunky and wouldn’t be a hold the switch for a smooth dimming.
BUT, you can program any of the single, double, or long buttons to run if statements and do xx,
You can do something like long hold down, for the button assignment you go down to select accessory and scroll to bottom and click convert to shortcut. Then you do IF light brightness is equal to or higher than 91%, set light to 90%, OTHERWISE, IF light brightness is equal to or higher than 81%, set light to 80%, OTHERWISE, IF, etc etc all the way down to 10% or whatever.
You can make that as granular as you want. Do the opposite for increasing brightness.
Downside is you have to keep initiating it. So you can only go down one level, then hit the switch again to jump to the next level. For that reason I would set it up to the most common brightness levels you use so you’re not at the switch for a minute trying to get it past levels you never use anyway.
Like I said extremely clunky but only way to do it at the moment to simulate actually dimming
