I purchased some Zigbee Iris 3320-L contact sensors for myself but I didn't need this many and the seller didn't want to break it up.
I am selling off the remaining 3320-L that I won't be using. It's new open box complete kit and it does include the battery and magnet. I already have paired a few to hubitat and the battery life are still at 100%
If you want to purchase one or more 3320-L, send me a message.
