Dutywall, the facility wall that becomes an alarm
An on-site digital-signage appliance that runs everyday facility screens and takes over with zoned emergency alerts.
Field notes
The system separates display control from the public internet: screens poll a local Linux box or Pi, and the optional cloud layer only exchanges agent-initiated state and status. Its alert model includes per-zone targeting, manual override, CAP and JSON inputs, and NWS-derived presets for tornadoes, flash floods, and winter storms. The page identifies East Tennessee and Western North Carolina as its initial design area, with facilities such as plants, schools, and hospitals in view.
