busylight

Raspberry Pi busy indicator light

Requirements

PowerShell Client

• Microsoft Teams
• Microsoft PowerShell 7.x

Start the client in the background by running the following in PowerShell:

Start-Job -FileName TeamsClient.ps1

Stop the client using the following:

Get-Job                  # Gets the list of Job IDs
Stop-Job -Id {Job ID}    # Stops the Job
Remove-Job -Id {Job ID}  # Removes the Job from the Job List

Note: Microsoft Teams Presence is available throught the Graph API. However, this requires the Presence.Read permission, and my organization has this permission restricted. As a workaround, a users' status is reflected in Skype for Business even though my organization uses Teams exclusively. The Lync API allows reading Availability, which reflects the same value as the Teams presence.

Server

• Raspberry Pi / Raspberry Pi Zero with SPI enabled (see below)
• Pimoroni Unicorn HAT Mini for Raspberry Pi - PIM498

$ sudo raspi-config nonint do_spi 0
$ pip3 install -r requirements.txt
