Wow! These devices on eBay shot up in price big time!
I should of just bought 12 right away.
Oh no! I'm glad I got mine when I did, then. I hope you're able to find some at a good price. If I see anything on other sites, I'll send them your way.
I use the IKEA Tradfri outlets and USB repeaters. The outlets are pretty cheap but they are really big. I have 5 of the USB repeaters in my house.
What battery does the V1 contact sensor use, I'd like to stay with the same batteries as I have for other sensors?
1x CR2 battery.
Good, I believe that is the same battery as the 3320-L's so I'm in luck!
It is! I'd purchased a score of them awhile back and was pleasantly surprised to see they are the same.
I only have one of the 3320-L's and bought a 10 pack of batteries (good deal on EBay) and it was the only device I had that used it, so this actually is a bonus in my book, plus the v1's being so cheap!
