CoolMasterNet Binding

The CoolMasterNet binding is used to control CoolMasterNet HVAC bridge devices (opens new window), using the "ASCII I/F" plaintext TCP control protocol.

Discovery

The CoolMasterNet protocol does not support automatic discovery.

Thing Configuration

• controller is a openHAB "bridge", and represents a single CoolMasterNet device. A single controller supports one or more HVAC units.
• hvac is an HVAC device connected to a controller. Each hvac thing is identified by a CoolMasterNet UID (refer to CoolMasterNet controller documentation).

Example demo.things configuration for two HVAC devices connected to a CoolMasterNet device found at IP 192.168.0.100:

Bridge coolmasternet:controller:main [ host="192.168.0.100" ] {
  Thing hvac a [ uid="L1.100" ]
  Thing hvac b [ uid="L1.101" ]
}

Channels

Channel	Item Type	Description
on	Switch	Turn HVAC unit on and off.
mode	String	HVAC mode (cool, heat, auto, dry, fan). Unit may not support all modes.
fan_speed	String	Fan speed (l, m, h, t, a ) for respectively "Low", "Medium", "High", "Top" or "Auto". Unit may not support all speeds.
set_temp	Number	Temperature target setpoint in Celsius.
current_temp	Number	Current temperature in Celsius at HVAC unit.
louvre	String	Louvre angle (0, a, h, 3, 4, 6, v) for respectively "No Control", "Auto Swing", "Horizontal", "30 degrees", "45 degrees", "60 degrees" or "Vertical". Unit may not support all angles.
