Not made by me, but someone in my office created a Lambda function, so we can ask Alexa if a meeting room is free, and it links into the Google Calendar API to check. It then uses a library to say how long until it is free in a human like way. You can also ask it to find if any rooms are free in the building, and most importantly if the pool table is in use or not! As well as that, there is even a web cam above the table that counts the balls, and can tell you who is winning!
