I have some X10 light switches for my outside lights. I'm running
ActiveHome to schedule them on and off at dusk and dawn. From time to
time they come on in a dimmed mode. Any thoughts why?

You need to give us more information. What model/make switch? Some switches
are designed to come on at the level they were at when turned off. Others
can be programmed to come on at a certain level. Still others have no
dimming but only on/off.

Dave,

One of the switches is an XPDI3-IW and the other is an XPD3-IW. It's
weird the way they are coming on at dusk in a dimmed state. For
instance, last night they came on at 30%, but both were the same, they
always are.

You mentioned that some of the switches are on/off only. Which ones?

I've found the part numbering schemes of X10, X10 Pro, and apparently
some other lines quite confusing.

AFAIK those are both only one way and I don't believe they have "memory
dim". However, I do not try to keep up with all of the latest features.

Do you have motion or dawn/dusk sensors that turn on the lights? Do you have
a phase coupler? It could be that you're experiencing collisions of PLC
commands with the result being a Dim command.

SmartHome's ToggleLinc PLC switch is On/Off only.

They also have a non-dimming ICON switch that can be configured for X-10.
