Wake-on-LAN

Add-on Marketplace Block Libraries

logo

This library adds a block to wake a Network device with a Wake-on-LAN packet. You need the Network binding installed and a configured device Thing. If you wish to use the MAC method, you should also provide the MAC address in the thing configuration.

This block will send a Wake-on-LAN packet to the specified network device, which you can select in a popup by clicking inside the thing block. Only choose a Network device when picking the thing.
Watch out for log messages if the operation doesnā€™t seem to work, for instance:

java.lang.IllegalStateException: Cannot send WoL packet because the 'macAddress' is not configured for network:servicedevice:mycomputer

Hi Yannick,

thank you very much for this binding, thats very cool and helpfull.
I have one problem and iā€™m stuck with it. I have a Ubuntu server which is not necessary to run 24/7. With my Openhab3 i would like to start it, which is working under some circumstances as followed.
I have a Openhab 3 Instance (3.2.0) running at a windows server VM on Ubuntu 18.04, installed via openhabian, which is running fine and without any problems so far. Actually i updated to 3.3 but the Problem seems to stay.
When i shut it down and send the ā€œmagic Packetā€ via Openhab within a few Minutes after the shutdown, the WOL works perfectly fine and the server start booting.
If i wait for example for more then 30 minutes and send the WOL packet from openhab, the server does not wake up any more.
If i send the WOL package from my pfSense firewall or straight from the router 30minutess later or more, the server respond straight ahead and start booting. I donā€™t have any error messages inside the logs. Iā€™ve implemmented the IP and MAC magic packet option inside the same rule to try both at the same time, but nothing changed. Iā€™ve already tryed to send the magic packets multiple times with a delay in between, but no success. Iā€™ve configured the server as a networkdevice, and selected port 9 inside the networkdevice binding settings to make sure the packet will send on the right port.
Do you have any idea or recommended settings for the binding i could try?
I would appreciate you help and/or feedback on that.

Regards Marcel

Hi Marcel,

Unfortunately I cannot help you with this issue, as this is just a Blockly script block that calls the Rule Actions of the Network binding:

You might want to open an issue on GitHub (Issues Ā· openhab/openhab-addons Ā· GitHub) to have the right people be aware of it and eventually have a look at it.
