MS Teams Status Updater for openHAB

Hi there,

i wanted to get my MS Teams Status into openHAB and use it to inform my wife wether i´m on the phone or not.
So i found this thread and the solution mentioned in the last post.

This is fine but i didn´t liked the fact that i either have a powershell window or no window at all.
The window is a visual indicator wether the script is running or not but takes space in my taskbar.
The no window has no visual indicator and i don´t know if the script is still running.

I searched for a solution to get the powershell script into a service that runs at startup and stops when shutting down the machine. This would also result in two new states that weren´t possible with the script only solution.

I found winsw and gave it a try.
After some trial and error i found a working solution i want to share with you.

What you need?

  • winsw - can be found on Github
  • Powershell ISE - should already be available on Windows 10
  • openHAB - yeah that´s obvious :slight_smile:

What you get!

  • A Windows service that updates an openHAB Item based on your MS Teams status
  • A script that reads the MS Teams logfile to get your status
  • A start and stop message to get more states for openHAB rules

1. Preparing winsw

  • Download the latest version you´re comfortable with (i used the version 3 alpha) as .exe
  • Prepare a folder where the service will work and the scripts will be placed later on
  • I choosed C:\Scripts\msTeamsUpdater
  • Place the downloaded WinSW-x64.exe inside this folder and rename it to something like msTeamsStatusUpdater.exe

2. Creating a config file

  • Start an editor of your choice (e.g. Notepad++) and create a file with the same name your choosed for the winsw.exe and save it at the same path (C:\Scripts\msTeamsUpdater)
  • In my example msTeamsStatusUpdater.xml
  • I used the following config for my service
  <name>openHAB Status Updater for MS Teams</name>
  <description>This service will update an openHAB Item based on your MS Teams status.</description>
  <arguments>-ExecutionPolicy Bypass -NoLogo -NoProfile -NonInteractive -WindowStyle Hidden -file C:\Scripts\msTeamsUpdater\Updater.ps1</arguments>
  <log mode="roll"></log>
	<arguments>-ExecutionPolicy Bypass -NoLogo -NoProfile -NonInteractive -WindowStyle Hidden -file C:\Scripts\msTeamsUpdater\Startup.ps1 -method Offline</arguments>
	<arguments>-ExecutionPolicy Bypass -NoLogo -NoProfile -NonInteractive -WindowStyle Hidden -file C:\Scripts\msTeamsUpdater\Startup.ps1 -method Online</arguments>
  <onfailure action="restart" delay="10 sec"/>
  <onfailure action="restart" delay="20 sec"/>

3. Explanation

  • <id> - needs to be a unique id for your service that isn´t used by any other service on your machine
  • <name> - the display name of your service
  • <description> - a description for your service that will be shown under services.msc
  • <executable> - in this case powershell to run the script that reads the MS Teams logfile
  • <arguments> - this list of arguments is something like a best-practice i found and it contains the path to your powershell scripts
    • In my example it´s the same path as for the service
  • <log mode="roll"> - thiss will create rolling logs with a default of 10MB per logfile and 8 rolling files
  • <delayedAutoStart> - this is very important to get the start message Online as otherwise the service would start too early and isn´t able to send this message
  • <poststart> / <poststop> - these are used to get a start and stop message with Online and Offline
  • <onfailure action="restart" delay="10 sec"/> - this will restart the service 10 seconds after it crashed and the second line will restart it 20 seconds after the second crash
  • More information can be found in the Github repository of winsw

4. The powershell scripts

  • Start the Powershell ISE
    • paste the following line for the first script
    • replace <openHAB-IP-address> with the ip-address of your openHAB instance
    • replace msTeamsStatus with the name of your status item
    • save it as Updater.ps1 in your working directory
Get-Content C:\Users\Michael.Bredehorn\AppData\Roaming\Microsoft\Teams\logs.txt -Wait -Tail 0 | ? { $_ -match "(?<=StatusIndicatorStateService: Added )(\w+)" } | % { if($matches[0] -ne "NewActivity") {& Invoke-WebRequest 'http://<openHAB-IP-address>:8080/rest/items/msTeamsStatus' -Body $matches[0] -Method 'Post' -ContentType 'text/plain' }}
  • Open a new Powershell ISE window
    • paste the following line for the second script
    • replace <openHAB-IP-address> with the ip-address of your openHAB instance
    • replace msTeamsStatus with the name of your status item
param ($method)
Invoke-WebRequest 'http://<openHAB-IP-address>:8080/rest/items/msTeamsStatus' -Body $method -Method 'Post' -ContentType 'text/plain'

5. Preparing openHAB

  • Create a new item with the same name you used in the scripts
  • In my example it´s inside a text based items file called presence.items
String msTeamsStatus "Current State of MS Teams [%s]"
  • You can also work with a .MAP transformation file to make the status more user friendly or translate it to your local language
String msTeamsStatus "Current State of MS Teams [MAP(]"
  • Example for the file
InAMeeting=In einer Besprechung

6. Install the service

  • Open a commandline with administrator rights
    • Open the start menu, search for cmd and click on Run as administrator
  • Switch to the directory were you placed the service, the config and your powershell script
    • cd C:\Scripts\msTeamsUpdater
  • Execute the following command to install your service
    • msTeamsStatusUpdater.exe install
  • The commandline should show you a success message
  • Open your services.msc and search for your new service
    • 2021-08-06 19_14_35-Window
  • Open the preferences and start your service
  • Check your openHAB item and if it´s changing to Online
  • Open your MS Teams, try to change the status and see if it´s pushed to openHAB
    • 2021-08-06 19_12_11-Window

7. Control a hue bulb with the new item

  • I´m using a color hue bulb to show the current state and switch the bulb on/off
rule "Teams Status Update"


    Item msTeamsStatus changed


    val currentState = msTeamsStatus.state

    switch currentState {
        case 'Online': {
            hueStatus_Temp.sendCommand(50) // White
        case 'Available': {
            hueStatus_Color.sendCommand("120,100,100") // Green
        case 'Busy': {
            hueStatus_Color.sendCommand("45,100,100") // Yellow
        case 'DoNotDisturb': {
            hueStatus_Color.sendCommand("45,100,100") // Yellow
        case 'BeRightBack': {
            hueStatus_Temp.sendCommand(50) // White
        case 'OnThePhone': {
            hueStatus_Color.sendCommand("0,100,100") // Red
        case 'InAMeeting': {
            hueStatus_Color.sendCommand("0,100,100") // Red
        case 'Presenting': {
            hueStatus_Color.sendCommand("0,100,100") // Red
        case 'Away': {
            hueStatus_Color.sendCommand(OFF) // Switching Off
        case 'Offline': {
            hueStatus_Color.sendCommand(OFF) // Switching Off

  • There might be more states but i wasn´t able to reproduce them alone
    • The out of office states are mixed with the normal status if someone is available and has an active out of office message

kind regards


Great! Already thought about that.
I think that I need to check, if I have the right permissions to go implement on my business environment.

Yeah that´s a problem for some business environments.
I´m in the happy state to have local administrative rights for my daily work.

It´s the same problem why i couldn´t follow the pull method over Microsft Graph.
My company hasn´t opened the feature for us so i´m not able to use it.
I would rather pull the status from Teams instead of pushing it from my working machine to openHAB.
