I have had Lutron-Caseta In-wall dimmer for almost 2 years and all of sudden, I see it lost power, that means no LED lights on. It has stopped working. I checked using power tester that current is coming fine to that outlet. I'm clueless on what might be working. Is this dead now? These are expensive switches to be honest, I don't want to spend another $65 to replace this if this is not that reliable and with life span of just 2 yrs..Any advice?
