Hi, I sympathize with you. I also went through 2 PLM's and had numerous problems. Smarthome tech support, in my humble opinion, is good at exchanging products rather than solving problems. Universal Devices was very responsive to my problem. Michel worked tirelessly and finally found that Avast Antivirus software was causing most of my problems. Try disabling your antivirus and if that doesn't work ask for Michel. Good Luck!

Question If I program the 2420 to have a 4 minute "On" time, does that mean that the 2420 does not recognize movement again for 4 minutes or does is reset to see motion after 1 minute as it does from the factory with the "on" time set at 1? Thanks for any reply.

I have not had good experiences with the 2420 M. The good news is that the low battery sensors do work and do send signals and trigger programs. The bad news is that my unit goes through batteries like my GTO went through a tank of gas. The sensor indicates that the battery is low and the unit stops functioning! My simple battery tester says both are good, and my amprboe indicates that the "dead" batteries are generating 8 volts each. The ISY-99 does allow one to reset the off time which is a great thing, although the ISY doesn't alway see the 2420. I believe it may be a conflict with Avast antivirus. Sorry I don't have any solutions. I spoke with smarthome and they offered to warranty them out. We shall see what happens.
