Worst decision I made was buying a Wemo dimmer. What company provides Smartthings compatibility with their switches but not their dimmers? Aside from that, use a virtual dimmer switch in Smartthings and your Wemo dimmer will work until you dump it. I use Inovelli and have zero problems. Like the fact I can program the lighting on the switch for different uses. I have one flash yellow if the garage doors are open. Another flashes red when the alarm is set.
