IOT Link - Windows Management using MQTT

Fally · January 15, 2020, 9:30pm

, they look like this in the config.yaml

Ciquattro · January 16, 2020, 6:42am

yes it was the solution

Pittini · January 16, 2020, 2:57pm

Hi everybody,

i try to connect my desktop-pc with iobroker via mqtt. My first try was Eventghost, its nice, but…the mqtt client there is junky and works just half of the time. The other time it produces errorlogs.
So i thougt, lets try iotlink and i’m happy the mqtt seems to be more stable.
Now, after installation and configuration it works how i need it, exept one thing:

I wish to send my monitor in sleep mode. In the commands addon this is possible via:
mqtt.0.iotlink.workgroup.mainframe.commands.displays.off
and
mqtt.0.iotlink.workgroup.mainframe.commands.displays.on

This is working but has a strange behavior.
First problem: Why are there two datapoints for it? I think a “screenoff”=true/false should be enough?
Second Problem: Those two Datapoints are switching on every switching flank, so if i want to use them, i first have to determine was the old state is.
Third Problem: It seems, that there is no Datapoint which tells me, the monitor is sleeping or not.

Isnt it possible to make this work like the mute function? There is an info datapoint and an switch datapoint with true/false - perfect.

Any suggestions?

@alexslx Unfortunately, the service crashes randomly after a while. This also happened with 1.x and now also on latest 2.x version, so it’s not an issue introduced in 2.x.

@Pittini

Screen commands can be improved for sure. I’ll take a look on it.

@lkhdas

Hi, sorry for your problem. This is known issue for me because of underlaying library used to communicate between the Windows Service and Client Addon used to issue commands to your current running user. I’ll try to improve on this but as it is now it should be reconnecting after any fatal errors.

@All

I’ll try to improve discovery and ‘undiscovery’ more. Also, pull requests are always appreciated.

NEED HELP:

If someone can help me writing a better and user-friendly documentation I would love that help. Sometimes I feel it is too much complicated for new users as I’m too technical

lkhdas · January 22, 2020, 6:17pm

@alexslx It does not reconnect after this unfortunately. The service will show as stopped in the Service Control Manager until manually restarted.

alexslx · January 26, 2020, 8:17pm

Hi,

I’ve released version v2.0.3 with some fixes related to service crashing and sleep/hibernate.

@lkhdas
You can try the new version as well.

grokshot · January 28, 2020, 12:57pm

I have an issue where when I restart Home Assistant the values from my servers are not populated until I RDP to my servers and restart the service. If the values change they are updated but this may not happen for a long period or at all. Is there a way to send a command to those servers from a button on home assistant to restart the service? Is there a better or different way to accomplish this?

I did look for an answer to this but couldn’t find one.

Thank you for the extremely useful application.

alexslx · January 30, 2020, 1:43am

@grokshot

Yes, there is a refresh command.

Let me link the wiki page:

You can use it with the start event from HA:

  - id: IOTLink_Startup
    alias: IOTLink Startup
    trigger:
      - platform: homeassistant
        event: start
    action:
      - service: mqtt.publish
        data:
          topic: "{prefix}/{domainName}/{machineName}/refresh"
          payload: ""

grokshot · January 30, 2020, 11:59am

PERFECT! Thank you!

bjorn1 · February 16, 2020, 4:35pm

Hi,

I have a problem where the service always crashes after around 2 mins. I can initally see the sensors and values in Home Assistant, and they were discovered automatically, but then no updates after the service has stopped. I have Mosquitto on the same Windows machine as IOT Link.

Here is the config:

  credentials:
    username: 
    password: 
  tcp:
    enabled: true
    hostname: 127.0.0.1
    port: 1883
    secure: false
  websocket:
    enabled: false
    uri: 
    secure: false
  messages:
    qos: 1
    retain: false
  lwt:
    enabled: false
    qos: 1
    retain: true
    connectMsg: "ON"
    disconnectMsg: "OFF"
  discovery:
    enabled: true
    topicPrefix: homeassistant
    domainPrefix: false
  clientId: homeserver
  prefix: IOTLink
  cleanSession: true

logging:
  enabled: true
  level: 4

and here is the log file:

Within ServiceLog, I’m getting spammed with:

(note, this is with log level 10)

Is this normal? Over and over. “Instance is already running. Skipping”

Second question:

Do the logs rotate automatically?

guice · February 16, 2020, 7:17pm

One more:

I just tried the Notification function. It works, almost. I’m getting THREE notifications per single call. Any clues as to why?

fantangelo · February 21, 2020, 9:32pm

Thanks for this excellent program. Ever since I updated to the latest version v2.0.3 I am getting this error in my logs and the Idle Time sensor no longer works. The other sensors do work. Can I provide any additional info?
Thanks

VMCosco · March 12, 2020, 4:39pm

Working great and love the new HA Discovery option.

Is there a way to grab external IP or to detect if a alternate network adaptor is connected? I would like to use this to create a sensor to monitor if my VPN is connected.

Greenhouse · March 18, 2020, 10:46am

Firstly, awesome bit of software - thanks very much

I’m struggling to ‘run’ programs using the run command. My script is:

my_computer_switch_to_tv:
    alias: "My Computer - Switch to TV"
    sequence:
      - service: mqtt.publish
        data:
          topic: "iotlink/workgroup/adampc/commands/run"
          payload: '{ "command": "C:\\ProgramData\\Microsoft\\Windows\\Start Menu\\Programs\\AMD Catalyst Control Center\\TV.lnk", "args": "", "path": "C:\\ProgramData\\Microsoft\\Windows\\Start Menu\\Programs\\AMD Catalyst Control Center", "user": "", "visible": true, "fallback": true }'

Which throws up the error:

[WORKGROUP\ADAMPC][2020-03-18 21:39:16 +11:00][ERROR][IOTLinkAPI.Platform.Windows.WindowsAPI]: WindowsAPI::Run() - CreateProcessAsUser failed. Error Code: 193

If I substitute the example run google chrome (from here: https://gitlab.com/iotlink/iotlink/-/wikis/Addons/Commands), it works fine (opens chrome with " https://iotlink.gitlab.io" tab open).

Am I not able to run a shortcut? Otherwise I tried this (where the shortcut is point to), with no luck:

payload: '{ "command": "C:\\Program Files (x86)\\ATI Technologies\\ATI.ACE\\Core-Static\\CLI.exe", "args": "Start Load profilename="TV"", "path": "C:\\Program Files (x86)\\ATI Technologies\\ATI.ACE\\Core-Static\\", "user": "", "visible": true, "fallback": true }'

Edit: Did it! Didn’t realise that you can only run .exe (and command line files?). The last one worked for me removing the " around “TV”.
