YoLink LoRa 1/4 Mile Wireless Range Smart Motion Detector, Indoor Motion Sensor, Motion Detector, Alexa, IFTTT, YoLink Hub Required
1/4 MILE EXTREME LONG RANGE, thanks to our unique LoRa-based wireless system. LoRa, short for Long Range is a new technology, superior to WiFi and older RF types, in range and obstruction-penetration. Capable of covering multiple floors, as well as multiple buildings on large properties.

Android phones offer similar functionality, depending on phone manufacturer). SMS messages are limited to the total of 5 times each device plus 5. A hub and two motion sensors provides you with 20 free SMS per month.
