The Denver Drupal Meetup

Open Media Foundation 700 Kalamath , Denver, CO 80204 (map)

This month, Joel Steidl will go over his solution for an automated door lock system built on Drupal 8. A friend had just purchased a Bed & Breakfast with an automated door lock system. He wanted to create a method to automatically send a guest their door keycode on the check-in date. Joel started wondering "can I build this in Drupal"? Yes!

Key Components:

Webhooks - Booking engine with webhook functionality. Anytime someone books a room or a booking is updated, this webhook is fired and pings a url in D8 that has been configured to consume the JSON data passed from the webhook.

Drupal’s Queue System - The JSON data from the webhook is added to Drupal's Queue system to be processed later as a booking entity containing the start date of their stay, contact information, etc.

CRON - Using Drupal's cron system, a check is made to see if any bookings are starting today. If there are, they are added to an Email queue and/or SMS queue to be sent out.

Twilio - For SMS notifications

SendGrid - For email notifications

Home Assistant - Using the REST API from Home Assistant (open source home automation software running on a Raspberry PI) we'll be able to automatically remove and add new PIN codes.

Although a complex setup, this method provides you with the security of ensuring the right people have access to your house. By leveraging Drupal, I was amazed how easily this could be pulled of. With all the great functionality in core, the solution requires minimal custom code.

Socializing starts at 5:30pm at the Intrepid Sojourner Beer Project. At 6:30pm we'll move to the Open Media Foundation for pizza and more conversation. Discussions and presentations start at 7.
