Types

type Config 

type Config struct {
	// NilanAdress is IP address and port of Nilan heatpump. Factory
	// default address is "192.168.5.107:502".
	NilanAddress string
}

Config holds network settings of Nilan heatpump.

func CurrentConfig 

func CurrentConfig() Config

CurrentConfig reads NILAN_ADDRESS environment variable and returns configuration. If environment variable is not present, function returns standard config.

func StandardConfig 

func StandardConfig() Config

StandardConfig returns factory-default adress of Nilan heatpump

type Controller 

type Controller struct {
	Config Config
}

Controller is used for communicating with Nilan CTS700 heatpump over Modbus TCP.
