Wake On Lan not working with HA 2024.2.0

[Langelus]

After updating my HomeAssistant to 2024.2.0 it seems that calling Wake On Lan does not work anymore, no sure what else to provide except the log so please let me know if you need anything more from me.

-- Servicecall that has worked until now --

Also experiencing the same behavior in 2024.2.1. It’s not just Wake On LAN, seems like it’s something with the service configurations that are busted.

This more generic service also fails with a similar log message:

service: pfsense.exec_command 
data:
  entity_id: binary_sensor.pfsense_home_pending_notices_present
  command: ping -c 1 google.com

While we wait for a fix to this custom component, here's another way to do this with Home Assistant and pfSense. This may actually even be a better long term solution for WOL that way it isn't dependent on an API connection to pfSense. Inspiration came from here.

1. Within pfSense, go to Services > DHCP server, select your interface, then scroll to the bottom and "Add Static Mapping"
2. Enter ff:ff:ff:ff:ff:ff as the MAC Address, and enter an IP address that is currently unused in your network.
3. Check the option for "ARP Table Static Entry" and save the entry. No other information is required to be entered.
4. Call the wake_on_lan.send_magic_packet service in Home Assistant that uses the Broadcast Address as the IP address you entered in step 2, like this:

service: wake_on_lan.send_magic_packet
data:
  broadcast_address: 192.168.2.252
  mac: 00:51:ed:39:1b:ce

That works well assuming the hass installation is on the same network (generally the case)!

It does actually work across vlans even though L2 is normally not routable

[bdf0506]

That works well assuming the hass installation is on the same network (generally the case)!

This method will also work across subnets, providing pfsense has a FW rule to allow UDP traffic over port 9 between Home Assistant and the target network. You just need the static arp to be on the network where your desired WOL device is.

Yeah I used the term network too generally there. I meant more broadly physical location. ie: won’t help if you’re connected to an instance of opnsense from a hass install over the public internet (I am aware of folks who monitor many opnsense installs broadly dispersed with a single hass installation).

The PR linked below is what caused the code to break and the fix is shown in the isy994 integration code changes from the same PR: https://github.com/home-assistant/core/pull/106759/files

Should be fixed in v0.6.5. Thanks to @raman325 !
