Building an Open Source Access Control System for Fablabs based on odoo and openHAB

Abstract

Controlling machine access in Fablabs and makerspaces is a crucial task. Different types of machines require different types of briefings. This is especially important to avoid damage and injury. Controlling access automatically is thereby desirable, as it is otherwise labor-intensive. Currently available software to organize Fablabs and makerspaces have either a rather high price tag or lacking the functionality for automated access control. Self-developed hardware is also quite common but often, due to regulatory constraints, not allowed to operate on mains. Also, there is a wide range of home automation devices that are certified for switching mains voltage. We have developed a prototypical system that makes these devices available for use in the access control of Fablabs and Makerspaces. We have identified openHAB as a useful solution for the abstraction of devices from various manufacturers.
