PLEASE Read before purchase.

LoRaWAN is propriety standard and the senor on this listing will only work if you have LoraWan Gateway, a Network server and an Application Server to make sense out of it. This device will not work with any other home automation product. It will only work with LoRaWan compatible products. Device is only suitable for people who are interested in LoraWan technology.

The current meter interface (4-20 mA DC) is designed to offer a large selection of easy-to-use current 4-20 mA data loggers for load monitoring. The wireless communication is compatible with LoRaWAN® protocol (ClassA).

Features

  • Wireless range of up to 10 km (depending on environment)
  • Requires 2 x ER14505 AA Lithium batteries (No included)
  • LoRaWAN® Class A compatible
  • Frequency Hopping Spread Spectrum (FHSS)
  • Improved interference immunity
  • Improved power management for longer battery life
  • Encrypt-RF Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
  • Over-the-air updates (future)
