Microsoft Graph IoT Room Meeting Display

iot_microsoft_graph_meetings.md

We currently use Joan devices to display upcoming meetings in rooms. It works OK, but they have drawbacks.

1. They are very expensive. Each device ranges between $500 to $899.
2. To get more features, you have to subscribe to a service for each device.
3. The wall mounts are a ridiculous $150 a piece. We have 16, which would mean we spend $2,400 on wall mounts alone!

Idea

Use the Microsoft Graph to determine the meeting schedule of each room and the attendees in our building. I want to build a Raspberry Pi attached to an E-Ink display that will display that information.

I also want to list the parts and build a wall mountable enclosure for this device.

Questions

• Can you use the Microsoft Graph to see rooms in your organization?
• Can you use the Microsoft Graph to see upcoming meetings?

Any code samples would be greatly appreciated.

OSS

Yes, I would like this to be Open Source.

@darrelmiller our rooms are set up as "individuals". The idea would be that each raspberry pi would be a proxy for that individual. So in a sense, I only need to look at that rooms individual calendar right?

Ah yes. That makes sense. So you can get a list of events for a user here https://docs.microsoft.com/en-us/graph/api/user-list-events?view=graph-rest-1.0&tabs=http

That's such a neat idea.
