Using Pharos

Pharos runs on the device that has the screen. Everything here is about that device.

  • install.md — getting the app onto a phone, tablet, TV box or streaming stick
  • fire-tv.md — the Fire TV reference device: developer mode, ADB over the network, and the platform's limits
  • onboarding.md — first launch and the three operating modes
  • troubleshooting.md — the screen is blank, the remote does nothing, the data is stale

The three modes, in one paragraph

In standalone mode Pharos fetches from sources you configure and needs no server of its own. In managed mode an external controller decides what the node displays. Hybrid is both: your normal dashboards run locally, and a controller can interrupt them with something urgent. Hybrid is the intended long-term shape, and nothing about standalone requires a Pharos server to exist anywhere.

What it costs the device

Pharos is designed against a 2 GB streaming stick, so the ceilings are real rather than aspirational: bounded caches, bounded queues, bounded logs, no unbounded history, no persistent raw video cache, no continuous local inference. A static screen should cost close to nothing while it sits there.
