Configure Emergency Alerts

The Emergency Alerts plugin checks active U.S. National Weather Service alerts and applies rules to matching Players. A rule can show Tilecast’s live fullscreen alert, show a ticker while playback continues, or start a ready playlist as a fullscreen response.

Caution

Alert delivery is best-effort and is not a life-safety system. Keep local emergency procedures and Wireless Emergency Alerts in place. Tilecast needs the server to reach the NWS service, and the plugin reports poll health so you can see upstream or network failures.

Install the plugin

An Owner or Administrator can open Operations > Plugins, select Add plugin, choose Emergency Alerts, and install it. Then open Emergency Alerts from the installed plugin list. Installation does not enable monitoring or create rules.

Choose which alerts Tilecast checks

1. In Emergency Alerts, turn on Automated NWS monitoring.
2. Under Alert coverage, select a State or territory. Choose Monitor entire state to include it all, or add one or more County or forecast zone locations. You can combine state coverage and specific locations.
3. Choose a Poll interval. Tilecast offers one, two, five, or fifteen minutes; the interface recommends one or two minutes for most sites.
4. Select Save NWS monitor.

Tilecast reads the locations from the NWS. If the location list cannot load, check that the server can reach api.weather.gov and retry. Use Check now to request an immediate poll. Last success, Last attempt, Matched rules, and Health show the latest monitor result.

Add a response rule

1. Under Weather event rules, select Add rule and enter a Rule name.
2. Enter one or more NWS event names, separated by commas, or leave the field empty to match every event that meets the severity and urgency thresholds. Names are matched without regard to capitalization; use the event wording shown by the NWS.
3. Set Minimum severity and Minimum urgency. An alert must meet both thresholds.
4. Choose an Emergency display:
   • Tilecast live NWS alert — fullscreen shows the event, headline, severity, affected area, instructions, sender, and expiration.
   • Tilecast live NWS alert — ticker bar leaves playback running and shows the alert in a bar. Choose whether it pushes content up or overlays the bottom edge, plus its height and speed.
   • Use a custom playlist — fullscreen starts a selected, non-empty playlist. Create or edit one in Tilecast Studio.
5. Set the Maximum duration, then choose at least one Target screens or Target groups. Enable the rule and select Add rule.

Only enabled rules and enabled monitoring act on alerts. Tilecast ends the response when the alert is no longer active or the maximum duration is reached. Fullscreen playback then returns to the schedule or fallback that applies at that time; a ticker is removed while normal playback continues.

Check a rule’s result

The Active weather emergencies list shows alerts currently matched to a rule and displaying content. If a rule is not acting, check that monitoring is enabled, its coverage includes the alert location, the rule is enabled, its event and severity/urgency match, and at least one target is selected. Check Health and Last success for NWS or network errors.

An Owner or Administrator can edit or delete a rule. A Viewer or other read-only role can inspect the page but cannot change monitoring or rules.

For a manual, immediate override that is not tied to a weather alert, see Start a Takeover.
