The well documented BACnet MS/TP and Modbus RTU cmmunications make it easy for system integrators to connect into existing building automation systems. The device has RS485 by default which can be configured to communicate using Bacnet MSTP or Modbus RTU protocols. There is also the Airlab Wifi model which supports communication over the Wifi lan using both Bacnet IP or Modbus IP protocols.
