This app connects to the Microsoft Graph API using an Azure AD app registration. After signing in to grant the application a user-delegated access token, the app queries the Graph API every 1 second to read the presence data of the first logged in user, and push it to two MQTT topics:
home/teamspresence/<aad_uid>/availability
home/teamspresence/<aad_uid>/activity
A DNS entry of 'teamsmqtt.home' pointing at the machine you are running this app on. This could be a hosts file entry on the machine you are signing in from, or a network-wide DNS record. This is due to the authorisation flow of AAD. (I may rewrite this at some point to use the more suitable device code auth flow)
An AAD app registration with the Presence.Read permission granted, and a return URL of https://teamsmqtt.home:3443/auth/callback.
Clone the repo.
Install docker-compose
apt-get install docker-compose
Copy .env.example to .env and fill in the required fields.
Build the images
docker-compose build
Run the app:
docker-compose up
Check the logs for any errors. Browse to https://teamsmqtt.home:3443/ and log in. You should then see some mqtt messages start to arrive!
If all is well, you can start the service in the background with
docker-compose up -d
You will need to sign in again each time the app is started. You will also need to sign in again after 90 days, as this is the maximum length of a Microsoft Graph API sign in.
This is almost certainly a buggy mess, written in sleep-deprived haste. This is also my first time deploying an app I've made myself using Docker and using Docker Compose. But hopefully someone will find this useful :)
