Good news: with the announcement of the new edge driver architecture, a community member has just released a new beta version of an edge driver for the hue dimmer switch.
Note that if you use the hue dimmer switch in this way, it will no longer be connected to the hue bridge and it will not show up in Hue app.
Also, I don’t know if this will work with Webcore or smartlighting: you might have to use the automation creator in the smartthings app. But you can ask the author.
And this is very early days for the new architecture, it is still in beta, so there may be glitches or changes over the next couple of months.
Finally, it doesn’t work with all smartthings hubs because Edge drivers don’t. For example, it won’t work with the Samsung Wi-Fi model. it should work with the V3 model or the new Aeotec hub.
