Requires an Ethernet Tag Manager.

• Immediate motion detection In "door mode", also detect garage-door/mail box door and other vertical door open-close (but not horizontal). 
  
• Programmable sampling frequency from 1Hz to 400Hz to balance between detecting fast movement and battery life. 
• Two types of motion event: "Moved" and "Carried away": The tag can distinguish short vibration that lasts less than a second from longer movement lasting more than 2 seconds.
• Less false alarms: The accelerometer is not susceptible to electro-magnetic interference from nearby appliances turning on/off. This allows you to increase the sensitivity to detect small vibration such as dryer running/not running, not possible with regular 3D compass based motion sensor tags.
  
• Beep to help find missing items
• Temperature logging and notification with 0.0625°C resolution temperature sensor (1°C error/noise in reading, after manual calibration. please choose products with higher grade temperature sensors for temperature monitoring)
• Logging interval programmable from 15 seconds to 4 hours.  
• Long wireless range allows placing inside most refrigerator/freezer to monitor temperature & door
• Out-of-range/back-in-range notification
• Unlimited storage of motion event data and logged temperature on cloud (can be deleted any time)
• Not optimized for usage in freezer, for detail see temperature Feature comparison matrix
