Bkenobi, I would never consider a DS10 or any X10 product for SENSOR for a driveway alert either! We use two different ones as we live 1/2 mile off the rd in the middle of woods and must know when someone turns down our driveway at the street. Have used for 30 years a winland electronics system (buried inductive pickup for metal vehicle detection). It has been near 100% effective. Then to tell progress of incoming vehicle or people, we have had for 20 years 3pc Chamberlain 1000 ft. Wireless Driveway Alarm Guardline Security sensors along the way, each beep coded 1,2,3 to identify their progress - good if they come in and do not make it all the way to the house... IRRC their receiver has a N.O. contact output available. Furthest sensor is 1,000ft away - directly thru the heavy forest trees. I feed the beeper signal from the street sensor thru an unused pair in phone line I ran throughout everwhere, run sonalerts. But it would be cool to feed THIS sig into HG so I could do things like send an email when not home if someone went down the driveway, etc...
Like Tuicemen, I do not have range issues with my DS10's, but for a different reason. When I first began using them, I DID have the normal range issues so they were not 100% reliable. That makes them totally useless iin an alrm system, so I moved ALL of them to an alarm panel, 6 feet away from my DS1200 and CM15a. Used pairs for each in old cat5 cable I have run everywhere (switched to mainly wifi so no longer used for network) to bring the actual door/window switches up to the DS10 panel. I have a few extra DS10's mounted, ready for other things - like this.
