Anel Binding

Documentation of the Anel binding for NET-PwrCtrl devices.

Introduction

Anel NET-PwrCtrl HUT	Anel NET-PwrCtrl IO	Anel NET-PwrCtrl HOME

NET-PwrCtrl devices are power sockets / relays that can be configured via browser but they can also be controlled over the network, e.g. with an Android or iPhone app - and also with openHAB via this binding. The NET-PwrCtrl HUT and NET-PwrCtrl IO also have 8 I/O pins which can either be used to directly switch the sockets, or they can be used as general input switches in openHAB. Here is a video demonstrating a switch and a dimmer (voice is German), explanation of the setup is given in the diagram below:

Note that the binding is still untested for other devices than the NET-PwrCtrl HUT, because I do not own any of the others. I suppose the binding works well with the NET-PwrCtrl IO because it has the same features, but it may not yet work for the others!

For installation of the binding, please see Wiki page Bindings.

The Anel binding is included since openHAB 1.6.0.

Binding Configuration

Configuration is done in the openhab.cfg file (in the folder ${openhab_home}/configurations):

########################## Anel NET-PwrCtrl Binding ###################################
#
# <name> must be an identifier that is also used for the item bindings.
# Example configuration: anel:anel1.host=net-control
# Example item binding: Switch f1 { anel="anel1:F1" }

# IP or network address (optional but recommended, defaults to 'net-control')
#anel:<name>.host=anel1

# UDP receive port (optional, defaults to 77)
#anel:<name>.udpReceivePort=7777

# UDP send port (optional, defaults to 75)
#anel:<name>.udpSendPort=7775

# User name (optional, defaults to 'user7')
#anel:<name>.user=user1

# Password (optional, defaults to 'anel')
#anel:<name>.password=anel

# Global refresh interval in ms (optional, defaults to 60000 = 1min, disable with '0')
#anel:refresh=60

# Cache the state for n minutes so only changes are posted (optional, defaults to 0 = disabled)
# Example: if period is 60, once per hour all states are posted to the event bus;
#          changes are always and immediately posted to the event bus.
# The recommended value is 60 minutes.
#anel:cachePeriod=60

Some notes:

• At least one option must be set for an identifier for the binding to work.
• The most obvious and important option is host, it is in fact mandatory if multiple devices are used.
• The host name, ports, and credentials are device-specific settings that must be configured via the device's browser interface.
• Port numbers above 1024 are recommended because ports below 1024 are typically reserved and their access restricted on some devices/networks.

Item Binding Configuration

There are different types of item bindings, all of them are qualified with the device's identifier used in the openhab.cfg file:

The device's name is a string type, the device's temperature is a number:

String anelName "Anel1 network name [%s]" { anel="anel1:NAME" }
Number anelTemperature "Anel1 temperature [%s]" { anel="anel1:TEMPERATURE" }

The actual relay states are also switchable if they are not locked. Note that the locked states and the relay's names are read-only.

Switch f1 { anel="anel1:F1", autoupdate="false" }
String f1name { anel="anel1:F1NAME" }
Switch f1locked { anel="anel1:F1LOCKED" }

The I/O states are only switchable if they are configured as 'input' (point of view of the anel device), otherwise they are read-only. Again, the names are also read-only.

Switch io1 { anel="anel1:IO1" }
String io1name = { anel="anel1:IO1NAME" }
Switch io1isinput { anel="anel1:IO8ISINPUT" }

Note: all read-only properties must be configured via the device's browser interface.

Example Rules

Although the device's configuration can be used to directly switch a relay with an input channel, the very same can be done with this rule:

rule "regular switch on Anel1 IO1 input for relay 1"
when Item io1 changed then
	sendCommand(f1, io1.state)
end

An input channel can also be used as a push button (also demonstrated in the video):

rule "push button switch on Anel1 IO2 input for relay 2"
when Item io2 changed to ON then
	sendCommand(f2, if (f2.state != ON) ON else OFF)
end

In combination with the MiLight Binding, this rule uses I/O 3 as dimmer for MiLight bulb milight_zone1 (also demonstrated in the video). As long as I/O 3 is pressed, the bulb dims up until its brightness reaches 100%.

import org.openhab.core.library.types.*

var org.openhab.model.script.actions.Timer timer2

rule "switch dimmer on Anel1 IO3"
when Item io3 changed to OFF then
	sendCommand(milight_zone1, 10)
	timer2 = createTimer(now.plusMillis(333)) [|
		val int newValue = (milight_zone1.state as DecimalType).intValue + 5
		if (newValue > 100) {
			timer2 = null
		} else if (timer2 != null) {
			sendCommand(milight_zone1, newValue)
			if (io3.state == OFF)
				timer2.reschedule(now.plusMillis(333))
		}
	]
end
