It seems like PCS, Simply Automated and HAI each has tried to differentiate their product from the others. When you really start digging, there are really lots of differences between the three lines. LEDs look different, what they control (LED, CFL, relay, etc. ) is segmented deferentially, how they operate is different, etc. I'm sure that the business geniuses at these companies that this would be a great plan, to me it seems like a big mess.
HAI makes relay switches, which you need to control an outlet correctly, SA doesn't. SA came out with a kludged ceiling fan switch, which others don't have. SA has one switch which dims or not, HAI has one for CFL/LED and another for incandescent although they never seem clear what the difference between them is, and both CAN control any type. (I have both types from HAI, CFL/LED and non-CFL, and honestly, the differences between them is minimal at best. The LED one seems to dim LEDs slightly lower before they flicker out, but the difference seems minimal at best.)
I suspect that the HAI timer issue is a UPStart bug, but I don't know for sure. Probably UPStart changed, and it broke this feature, and nobody from HAI bothered to do any testing.
I guess its good many years later that all three lines are still are still while they split a rather limited market, but it sure would be nice of they could unify things. The real competitors are not each other but rather Z-Wave, RadioRA, Zigbee, etc.
