Battery not included. For sale a new in open box Xiaomi Aqara Zigbee Window Door Sensor. I bought this originally with the intent of setting up a Zigbee security system but never got around to it. Now selling on, please note that while the battery is shown in the pictures please assume that this is empty and needs replacing as had this sit a while. You will need a Xiaomi Zigbee hub or Samsung Smarthings Hub in order to connect this to it and set it up, additional drivers may be required if you are you use a Zigbee hub not manufactured by Xiaomi. I also have for sale a bunch of door sensors and a vibration sensor for sale, see my other listings, can combine postage if you buy a couple. This listing is for a single door sensor
