I bought batches of them from ebay.com - lots of to choose from there. and sometimes cheaper. makes it easier to add multiple switches to one ds10 sender....
I do have a DS10 question for the wizards tho: after loosing my 100k ahp file (I know shud have backed up better) and rebuilding it, I am now down to the last stuff, and that is the DS10's. I have them all mapped thru V572RF32 and they all work there and their remapped standard x10 16bit codes all work in ahp. But the Onalert add-in refuses to see any of them! I stick DS10 into a room, hit the install button, and wait for signal but none see any. I took one up next to the cm15 to see if my antenna was bad; nothing. my ant is good as I can see plenty of RF activity otherwise. I had to remove and reinstall ahp and all add-ins multiple times in order to try to get my old ahp file to work (before I gave up and started building a new one). Just reinstalled onalert again and ds10s still are not seen. any one seen this before?
