Improvement Planning

Protocols

Use the MQ Telemetry Transport (MQTT) protocol to talk between the various components of hackspace infrastructure (locks, doorbell, access to tools, vending & arcade machines etc etc)

Nottinghack have already successfully used this protocol in their intrastructure, we should either reuse or learn from what they've been up to.

Hardware

Feature requests

Forgotten card code

If a member has registered their mobile number, text them a four-phonic code which will unlock the door. Code will only be valid for, say, 30 minutes.

Doorbell broadcast

Allow any device on the network to subscribe to the 'doorbell pushed' signal. Would allow for some cool doorbells to be hacked together.
