Not sure if you were able to try out 'Dim with Me".
I just started to look at Trend Setter and I thing I see why it’s not going to work with Trend Setter. From the release post [quote=“Kriskit, post:1, topic:31286”]
the master device is not a physical device

So basically the master device is a virtual dimmer. Since it is it’s own device, to make it mirror any other physical device, you would need a smartApp that controls both the on/off and level. So you would still need an app like Dim with Me to control the trend setter virtual dimmer.
Since “Dim with me” already can control a group of light, that seem a bit redundant (unless I’m missing a key feature in Trend Setter).
IF you really want to use Trend Setter and the OSRAM switch, the either merge the OSRAM device type with Trend Setter dimmer, so they are one device or use the Device Type below, which bind directly to devices. You could bind the Trend Setter dimmer to the OSRAM switch.
