Evolve Dimmer Switch To Control Sylvania IQ Bulb

Hello all. I’d like to be able to have my dimmer switch also control a sylvania iq bulb (that is attached to a permanently on sconce on a different circuit).

I seem to be having trouble getting an event to trigger (and then handle it) when the dimmer changes levels. Any ideas on the best way to do this? Thanks!

Adding onto this is a sort of secondary set of questions.

Would I need a switch that supports “instant status” to do this (I want to be able to physically touch the z-wave switch and dim the zigbee bulb on a different circuit) with relatively good feedback?

Or does SmartThings support the trick where a device will send out a “poll me now” type message when it has physically changed? If so is there anything special that needs to be setup to do this?

Thanks again!
