It wires to the HVAC communication bus (outdoor or indoor line, depending on brand) and exposes every indoor unit in ETS as group objects: on\/off, mode, setpoint, room temperature, fan speed, louvers, error codes and more, with no per-unit interface needed in the ceiling.\u003c\/p\u003e\n\u003cp\u003eBuilt for high-end residential and small-to-medium commercial projects with up to 32 connected units, it keeps Modbus RTU\/IP, BACnet IP\/MS-TP and REST API available on the same device, so a KNX system, a BMS and the CoolAutomation cloud apps can share one gateway.
