# 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 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. Eachhvac
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" ]
}
