I now have

a button that can turn my pc on and off.

automation that turns my pc on when I turn on my office light at night.

All while my units speaks to me…literally.

There used to be automation that would turn on my pc at morning time on weekdays but that proved to be somewhat counter productive.

Will add video in a sec.

There is built-in support in the forum’s editor for formatting source code, no need for images of the source code and people can just copy-and-paste your configuration.

dennisaion · April 22, 2016, 3:53pm

Tried copy and pasting it in (hence numerous edits) but formatting was off.
So I was stuck doing the image thing. Sorry.

danichispa · April 22, 2016, 3:56pm

To format messages try putting three backticks ( ` ), then a new line, paste your config, and on another new line, three more backticks.

dennisaion · April 22, 2016, 3:58pm

Thanks. Will give that a whirl…

Done!

darthninja18 · July 18, 2016, 5:19pm

Here is a total newbie and dumb question for you. In your setup is the host: 192.168.x.x, is that the computer being woken up, the router, or the HA host. I’ve seen host used in all three instances so I’m a little lost. Thanks

dennisaion · July 24, 2016, 5:02pm

Thats the target that needs to be woken up yes. And only questions unasked are dumb.

darthninja18 · July 24, 2016, 5:21pm

Ok follow up, is there a special program that needs to download to make that work. I have the Computer begin woken up ip address and it’s not showing any change at all. Thanks

FitzZZ · July 24, 2016, 9:32pm

Just a quick note: WOL isn’t supported since Windows 8 - it collides with fast-boot as far as I can recall. You might need to disable this feature in order to get WOL back.

dennisaion · July 25, 2016, 1:42pm

Your network card needs to support WOL. If onboard card check your BIOS for WOL feature being enabled.

darthninja18 · July 25, 2016, 4:13pm

I can turn on and off my computer, it’s just the feedback that doesn’t work. I didn’t specify that very well. It made sense in my mind. I followed your set up at the begining of the post and that works great. I can turn it on and off from anywhere. The feedback saying if it’s on just doesn’t work. At the moment I’m using a template to change being home to on and not_home to off then doing it that way. It works, but it takes 2-3 minutes to get the actual reading.

dennisaion · July 26, 2016, 4:18pm

Ah yes you mean the tts part. For that you need to install a tts engine which you can call from commandline.

darthninja18 · July 26, 2016, 6:11pm

not quite, I’m having a hard time expressing my question. The switch once I turn my computer on the switch shows it as off, and doesn’t change to on. I have to use a template sensor to make the switch move, which takes 2-5 seconds to show a change. If the switch doesn’t change I can’t turn it off cause it’s saying it’s off.

host (Optional): The IP address or hostname to check the state of the device (on/off). <— this is what I can’t get to work. Checking the state of my computer being woken up.

I appreciate the help so far. Now I can also do the tts stuff, I wasn’t planning on it, but now I have a direction to to when I want to. That is what I love of this community. There is always someone somewhere willing to help. Thanks for all the info guys.

dennisaion · August 6, 2016, 4:02pm

So switching on work but you can not check the state of your PC is what your saying?

You are running HA on a Raspberry correct?
And you have device tracker setup using nmap?
Nettools installed etc?

That is what is needed to check online status based on IP or MAC.

Add the PC as to be tracked device in known_devices.yaml

I am getiing the following error:

homeassistant.bootstrap: Invalid config for [switch.command_line]: [offcmd] is an invalid option for [switch.command_line]. Check: switch.command_line->switches->pc->offcmd.

platform: command_line
switches:

turn_on:

turn_off:

Any ideas?

Mister-Espria · September 14, 2016, 10:55pm

There was a breaking change in the update 0.28 for de command line switch component.
“offcmd” needs to be changed to “command_off”
“oncmd” needs to be changed to “command_on”

check for more information the command line switch component page.

I hope this helps.

mefistofelis · September 16, 2016, 6:35pm

thx that fixed that issue but my switch isnt appearing although i see it in the entities.

I have also created a group for it in order to show up.

I have seen in other threads that there are people facing the same problem.

Any ideas for that?

Mister-Espria · September 16, 2016, 9:45pm

hmm, i assume you checked your config with:

hass --script check_config

you did also setup the customize part correctly. so that the switch.copy is not hidden.

Then what you can try is to temporarily delete the default_view: group. (if you have that one).
You should see alle your devices in de home tab after restart. So the missing switch should pop-up also.

mefistofelis · September 16, 2016, 11:15pm

thx , so stupid of me, it was set to hidden

silvrr · September 24, 2016, 11:17pm

First off thanks for posting this, I hadn’t thought of using net rpc to shutdown computers.

However, I cannot seem to get it running. Using YAMLlint I have a valid setup but Home Assistant doesn’t like it.

16-09-24 18:09:53 homeassistant.bootstrap: Invalid config for [switch.command_line]: [Desktop] is an invalid option for [switch.command_line]. Check: switch.command_line->switches->Desktop.

My swtiches section looks like:

switch 1:
  ## 433 Mhz Radio Switches ##
  platform: rpi_rf
  gpio: 17
  switches:
    Living Room Lamp 1:
      code_on: 12345
      code_off: 12345
      protocol: 1
      pulselength: 194
    Living Room Lamp 2:
      code_on: 12345
      code_off: 12345
      protocol: 1
      pulselength: 194
    Front Porch Light 3:
      code_on: 12345
      code_off: 12345
      protocol: 1
      pulselength: 194 
    Garage Lights 4:
      code_on: 12345
      code_off: 12345
      protocol: 1
      pulselength: 194
    Spare Switch 5:
      code_on: 12345
      code_off: 12345
      protocol: 1
      pulselength: 194

switch 2:
  platform: command_line
  switches:
    Desktop:
      command_off: net rpc shutdown -I 192.168.0.0 -U user%password

Username and password (removed above) and IP address are all correct and work in putty to shut down the computer. The error seems to be somewhere in how my switches are setup. I tried using a phrase other than desktop but that didn’t help.

Thanks in advance!
