Insteon dimmers and keypads dying

Hi,

I have many Insteon dimmer and Keypad in my house.

Those devices caused to much light in room at night.

Since we have an option in the plugin to adjust the brightness, I set an event that dimmed every dimmer and keypad at night and set them back in the morning.

Lately, I had to replaced 2 keypads and one dimmer. They started acting wired, buzzing. Wife and kids were earring some noise coming from one of the keypad.

Tonight, the bathroom dimmer start flickering the load upon ramping on or off.

Is it possible that reprogramming the brightness 2 times a day could cause Insteons products to die?

It's starting to cost to much...
