Switch creation / Wake on LAN

Teuflor · December 15, 2021, 10:50am

hello, im very new to Home Assistant but i really to to learn as much as possible.

i want to wake up my NAS, it already works if i do this via shell script or shell command.

my problem is thad my config dont create any switch!
it doesnt matter if i write my code in an new .yaml file and include this or directly in configuration.yaml.

in my case it looks like this:

#top config
wake_on_lan:

switch:
  - platform: wake_on_lan
    mac: "AC:XX:XX:XX:XX:XX"
    name: "Hostname"
    host: "192.168.0.7"

i checked the spaces (2 in front of -platform, 4 in front of name,mac,host) checked the config, rebootet hassio etc. etc. i really dont know my problem.

thank your for your time!

greetings

i tried with ---- instead of ::::. nothing changed

probable I have expressed myself incorrectly.

My problem is not the wake_on_lan function!
My problem is that the switch is not created. Doesnt matter if i write the mac with : or with -. the switch does not apear…

# Example configuration.yaml entry
switch:
  - platform: wake_on_lan
    mac: MAC_ADDRESS

i am one step further now.

i copied my config 1 : 1 to another instance of Homeassistant, and hey… the switch apears there!
Also the standard switch from the switch documentation works for me. only the WOL switch doesnt apear.

any idea?

dirtymike0330 · December 15, 2021, 9:29pm

You’re not looking for anything specifically that says WOL right? Your switch will be named switch_yourcomputername

Teuflor · December 15, 2021, 9:30pm

yes. when im searching (after restart) for “switch.” it wont apear… my blind switch apears…

dirtymike0330 · December 15, 2021, 9:40pm

Can you try and just put the switch in your config file, rather than calling back to the switch.yaml? I know it should work the way you have it, but maybe a different method will knock something loose. For example, in my configuration.yaml, I have:

switch: 
  - platform: wake_on_lan
    mac: "xx-xx-xx-xx-xx-xx"
    name: "MewMew"
    broadcast_address: "xxx.xxx.x.xxx"

I have another PC below that as well. Both switches show and work with WoL

thanks for replay, i allready tried this. but nvm here again! i just edited like you wanted:

still no switch after restart…

Check your logs. Are there any errors?

Teuflor · December 16, 2021, 9:45am

Hi @ondras12345,

also checked! No Entry…

i dont get it what the problem is… same code on other instance works.

ondras12345 · December 16, 2021, 10:09am

Ok, this is probably not going to help, but try refreshing the frontend with ctrl+F5. That should ignore your browser’s cache and reload everything. It sometimes happens to me that when I add a new entity, I cannot access it from the entity filter quick bar. Maybe this is something similar.

Teuflor · December 16, 2021, 10:55am

also dont works i think i try a reinstallation…

ondras12345 · December 16, 2021, 11:09am

Try changing the name of the switch. Maybe there’s some weird name conflict.

Teuflor · December 16, 2021, 11:30am

good idea! tried it, but dont worked

You have quotations for both name and mac address and the host is commented out - this is wrong.

Here is what I have in mine and it works:

switch.yaml

- platform: wake_on_lan
  mac: 00:11:22:33:44:55
  name: server
  host: 192.168.1.X
  turn_off:
    service: shell_command.turn_off_server

configuration.yaml

## wol ##

wake_on_lan:

shell_command:
  turn_off_server: "ssh -p 59622 [email protected] 'sudo systemctl start systemd-suspend'"

and add this to point your configuration.yaml to the switch.yaml file

# Configure a default setup of Home Assistant (frontend, api, etc)
default_config:

# Text to speech
tts:
  - platform: google_translate

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

## New entries

switch: !include switch.yaml

That pretty much it and ensure you follow the WOL guide for the rest as previously posted above by @krskrab:

Good luck and hope this helps

Note: I am using fedora for my server with NVIDIA card so my command to suspend differs from the WOL guide in HA

I have a problem getting the shell script to work to turn off the server. The current code is:

switch:
  - platform: wake_on_lan
    mac: "00:11:32:26:xx:xx"
    turn_off:
      service: shell_command.turn_off_kanga

shell_command:
  turn_off_kanga: "/usr/bin/ssh -i /config/scripts/id_rsa -o UserKnownHostsFile=/config/scripts/known_hosts [email protected] 'sudo shutdown now'"

I have automatic login into the synology server based on key pairs and “sudo shutdown now” can be used by the user on the server without password. known_hosts and id_rsa has been copied to the /config/scripts directory.

When I turn the switch off I get an error 255 so it seems the login into the server seems not to work. Anyone understands what goes wrong?
