It's my understanding that you won't be able to use a dimmer for the outlet to dim the LED strips. The power supplies do not handle dimming well. They prefer on or off. The only real way to set the brightness of the LED strips is to use the remote that works with the controller. Then you can use an Insteon switch to turn them on and off. This is how I am doing mine after asking nearly this same question in my thread. Kinda sucks but the credit card size remote that you can get with the controller isn't bad to use.
