PresenceLight is a solution to broadcast your various statuses to various kinds of smart lights. Some statuses you can broadcast are: your availability in Microsoft Teams, your current Windows 10 theme, and a theme or color of your choosing. There are other solutions that do something similar to sending Teams Availability to a light, but they require a tethered solution (plugging a light into a computer via USB). What PresenceLight does is leverage the Presence Api, which is available in Microsoft Graph, allowing to retrieve your presence without having to be tethered. This could potentially allow someone to update the light bulb from a remote machine they do not use. I welcome all contributions here, as I am no expert in WPF/MSIX things.
