Main highlights

•READ BEFORE YOU BUY: The Z-Wave stick is for advanced users only, NOT for beginners. You must be comfortable with programming and have expert computer and Z-Wave knowledge to use this device. NVM back-up from 500 or 700 series Z-Wave sticks will brick the device. Do NOT apply NVM backups or firmware updates published outside of the Zooz support portal to avoid bricking the stick and voiding its warranty.
•NEW 800 SERIES Z-WAVE LONG RANGE: Take advantage of the latest wireless innovation with Z-Wave Long Range that extends your network coverage up to a mile. NOTE: Your home automation software needs to support the Long Range implementation on the interface side as well as the end Z-Wave device you add to the network for the Long Range functionality to be fully unlocked.
•WHAT YOU NEED: This 800 Series Long Range Stick adds Z-Wave Plus and Z-Wave Long Range capability to your DIY smart home set-up. You'll need a dedicated computer (PC, laptop, or Raspberry Pi, sold separately) and home automation software of your choice (not included) to complete the system.
