CoolMasterNet Binding

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

Discovery

The CoolMasterNet protocol does not support automatic discovery.

Thing Configuration

• controller is an 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
