µFi: a small UniFi controller

NOTE: no controller yet, just libs for handling inform. Making public early as pixiedust needs this.

Design Principles

1. Small systems
2. Low complexity

Resources

UniFi inform protocol: https://jrjparks.github.io/unofficial-unifi-guide/

Use-cases

• Run controller on small OpenWRT router
• Unattended system to upgrade devices prior to deployment (if old SW, adopt, upgrade, default).

Protocol notes

Controller returns 404 on inform if device has not been adopted.

Questions

• How does controller generate new shared secrets?
