Wake on LAN Binding (WoL)

Documentation of the Wake-on-LAN binding Bundle

Introduction

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

Generic Item Binding Configuration

In order to bind an item to this binding, you need to provide configuration settings. The easiest way to do so is to add some binding information in your item file (in the folder configurations/items). The syntax for the Wake-on-LAN binding configuration string is explained here:

wol="<broadcast-IP>#<macaddress>"

To prevent same mistake made by several people - the IP address is not the one from the machine you wanna wake up - this is identified by MAC address. IP is the broadcast IP from the SubNet; Here some examples for a typical C class network: - 192.168.1.255 for the destination IP 192.168.1.10 - or 127.0.0.255 for 127.0.0.15.

Here are some examples of valid binding configuration strings:

wol="192.168.1.255#00:1f:d0:93:f8:b7"
wol="192.168.1.255#00-1f-d0-93-f8-b7"

As a result, your lines in the items file might look like the following:

Switch Network_OpenhabWebsite	"openHAB Web"	(Status, Network)	{ wol="192.168.1.255#00:1f:d0:93:f8:b7" }

The item binding can be combined with an exec binding to be able to switch the system on and off. The example below works if openHAB is running on a windows host.

Switch networkPC "Computer" (network, gOGBuero) { wol="192.168.10.255#00-DE-AD-BE-EF-00", exec=">[OFF:shutdown -s -m \\\\192.168.10.23 -t 0 -f]" }

The example below is for openHab running on a linux host.

Switch networkPC "Computer" (network, gOGBuero) { wol="192.168.10.255#00-DE-AD-BE-EF-00", exec=">[OFF:net rpc shutdown -C MESSAGE -I 192.168.10.23 -U USER%%PASSWORD -f -t 120]" }

Note: For windows computers not in a Domain the firewall must be configured properly (allow remote shutdowns) and the DWORD-Regkey LocalAccountTokenFilterPolicy in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System must be set to 1.
