IoTaWatt Binding

This binding integrates IoTaWatt™ Open WiFi Electric Power Monitor (opens new window) into openHAB.

Limitations of this version:

• No authentication support

Supported Things

The IoTaWatt binding supports one Thing called iotawatt.

Discovery

The binding does not auto-discover the IoTaWatt device.

Thing Configuration

IoTaWatt Thing Configuration

Name	Type	Description	Default	Required	Advanced
hostname	text	Hostname or IP address of the device	N/A	yes	no
refreshInterval	integer	Interval the device is polled in sec.	10	no	no
requestTimeout	long	The request timeout to call the device in sec.	10	no	no

Channels

The binding detects configured inputs and outputs and creates channels for them.

Channel	Type	ID	Read/Write	Description
Amps	Number:Power	amps	RO	The current amps
Frequency	Number:Frequency	frequency	RO	The current AC frequency
Power Factor	Number:Dimensionless	power-factor	RO	The current power factor
Apparent Power	Number:Power	apparent-power	RO	The current apparent power
Reactive Power	Number:Power	reactive-power	RO	The current reactive power
Reactive Power hour	Number:Power	reactive-power-hour	RO	The current reactive power hour
Voltage	Number:ElectricPotential	voltage	RO	The current voltage
Power Consumption	Number:Power	watts	RO	The current power consumption
Phase	Number:Dimensionless	phase	RO	The current phase
