Communication between multiple OWLs for updating/logging/monitoring

[geezacoleman]

Currently for a multi-OWL system every unit is entirely independent. Communication between OWLs for easy updates/monitoring from a central location and powering on/off would be a considerable improvement.

Requires:

• addition of hardware (cables)
• comms protocols
• ?

Interface shouldn't be too much of an issue. Physical (ethernet) just means you need a switch, which can be annoying since so many are AC based. Wifi has the issue of interference from machines (i.e. high ping, dropped packets, devices falling off the network).

Comms protocol recommended would be MQTT. Will write something up over the next couple of months that works good enough for OWL.
