IOT Link - Windows Management using MQTT

freakshock · March 18, 2020, 6:46pm

Is it possible with IOT Link to monitor when a Windows 10 PC has been locked or not?

mattstein111 · March 20, 2020, 2:55pm

Does IOT Link expose camera on/off state to MQTT? I don’t need a screenshot of the PC screen or to take a picture with the camera, but I want to integrate with HA based on the status of camera on/off.

In this time with many of us working from home, I’m trying to fashion a simple ‘on air’ light kind of thing, and want to turn on/off with HomeAssistant based on the MQTT presented status of my Win10 desktop camera’s being in use.

Thoughts?

This is realy good program.

I also have mac computer and I wanna control it like this.

Is there similar program for mac os x?

incredible!
I am trying to implement that same casustic …
I would like to detect when I am in a video call to prevent someone from entering the room where I am working.
What type of light have you thought to use?
thank you @mattstein111

There are a number of good options on Amazon, ranging from the amusing (that literally says ON AIR) to the basic (simple small red light). The other thing I was considering (but have moved on from) was to use an Innovelli zwave dimmer with RBG notification bar to go red when on a call, vs green when off.

Once I get this working I’ll also turn on the in-fill lighting I have that makes my video conferencing look less filled with shadows.

Hi,
i managed to install this and get it up and running.
i have an issue that when I run a program it doesn’t focus on it, is there a way to force the focus?

also, does anyone has a script for increasing\decreasing volume by 1?

edit: changed to send.keys method and it works better

Having the same issues, any luck?

Having the same issue. Already tried disabling most of the sensors in the monitor addon but doesn’t seems to work. Only mqtt message I see is LWT. Did you have any luck solving this?

Fma965 · April 4, 2020, 11:21am

unfortunately not, i assume it to be a issue with our builds of windows 10, i have contacted the creators discord, git repo etc but no reply from any of them, think the project is dead, atleast for now.

For whatever reason mine worked for about 10 minutes and then it just stopped. To resolve this I used task scheduler to restart the service. To play it safe I’m doing every 5 minutes and for the last six hours it has worked great with no issues.

To learn how to use task scheduler to do this here are the instructions I followed, except with the service name being “IOTLink”.

Good luck!

Sorry, no. I have given up on this option for now.

Hi all, I’ve just had a breakthrough with getting this to work.
Firstly, uninstall and delete all previous IOTLink software (windows), it doesn’t appear to update very well,
then remove or #comment out the iot sensors, integration etc in HA.
Start again from scratch, the present IOT is 2.0.3 I believe. Even though I had installed it as admin on windows I still had to find the IOTLink server process in Task Manager, open it’s properties and set it as ‘Run as Administrator’ - I did both IOT entries to make sure.
Use Integrations to discover the MQTT sensors or un-comment the entries from before.
Now it works. Mostly. I can’t get CPU info yet but that’s next to sort out. Hope that helps.

I have an idea to monitor Zoom Meeting (My Son is having online classes) to check is he is on meeting or not. One way could be to find window by name. Another way could be to execute command tasklist /v /fo list /fi "imagename eq zoom*"| find /i "window title:" (or something like this). So when there is window with title beginning “Zoom Meeting ID” it means that meeting is ongoing if no such window then it is not started. Can someone advice me on how to achieve this?

My next automation will be to use NodeRed to push reminders to Amazon Echo to remind him to start class.

KAjFASH · April 22, 2020, 4:17pm

Solved my issue, anyone can use my solution https://github.com/exKAjFASH/IOTLink

I’ve tried to work with Zoom API, but their APIs do not provide “In A Meeting” status, for example GetUser returns “active” status when you are on the meeting or not. Another APIs related to meetings provide only meetings created by this user and do not show meetings where user is joined so I’ve ended up digging their API.

Then I’ve spent some time to understand how addons are working in IOTLink and as for me it better to provide sample project which anyone can use as a base to start, so I’ve copied commands addon, removed unnecessary code and implemented functionality using FindWindowClass. As Zoom do not show meeting ID in title I’m unable to get it. But able to check Zoom video window by it’s class “ZPContentViewWndClass” - when it exist and visible then meeting is ongoing which is enough for me.

Hope it will be helpful for someone. Thank you for IOTLink - I’ve added several sensors to my HA.

Pretty neat! Not sure that I have a use case for this but I like the idea.

James_Huang · April 23, 2020, 7:30am

Is there any mechanism to run a batch file and return the outputs via sensor?

davidmateos · April 26, 2020, 10:59am

Same issue here.Did you find a fix for this issue?

Looking for something similar. I have some Powershell I want to execute, and collect the output (which will always be a number). Anyone found a way to do this?A

I am having an issue when it comes to publishing to a topic.

I have my MQTT Broker set up via the Add-on.

I have the MQTT integration set up.

I have IOT Live running on my computer.

I was able to auto discover all the sensors, binary_sensors and camera entities

But if I want to run a command via a script or even the MQTT panel (developer tools -> mqtt) nothing happens. No logs in HA or the Addon. Nothing in IOT link as well.

Running the MQTT explorer and connecting using the same creds. I am able to send the command and the commands action happens on my computer. Ex. iotlink/workgroup/desktop-name/commands/lock from the explorer will lock my computer. From Home assistant, nothing happens.

Is there something I may be missing?
