I have replaced almost every switch in my house with Caseta Wireless Dimmers and Switches, and most work totally fine. However, the under-cabinet lighting in my kitchen does not work properly. It consists of seven "WAC Lighting" dimmable LED units (LEDme® Light Bars) that are all controlled by a single switch. I had tried using a Caseta Wireless Dimmer but it did not work at all and WAC lighting claims that you can wire together at most 4 when using a dimmer. So I swapped out the Caseta Wireless Dimmer for a Caseta Wireless switch, PD-6ANS-WH.
The switch works and is wired properly including neutral and ground. However, even when the Caseta switch is "off" it seems to be bleeding enough current to (very) dimly light up all 7 under cabinet units. I fail to understand what is going on here - I expected that a dimmer would be slightly more complex, and that even when on fully a dimmer is never 100% and when fully off it's not 0% but I expected a $55 on/off **switch** to act like an actual relay, where the circuit is disconnected fully when "OFF".
Is this likely a faulty switch or a flaw in the design? Why is the Caseta switch bleeding/leaking current when it's off?
Thanks,
Jack
