NOTE: *Maximum number of devices according to protocol specifications and guidelines.
NOTE: **There is one onboard RS485 port, an additional can be added via USB.
NOTE: ***LoRa distances - LoRa is noted for its long range and deep penetration. LoRa transmissions can penetrate glass, metal, and concrete found in most buildings. Radio's antenna and installation can affect the range of LoRa sensors. You must test the transmission and signal strength, when you install wireless devices.
