Where the Signals Come From
Signalio watches the official sources below and turns their notices into alerts on the map.
Alerts over Meshtastic when there is no mobile network
In the mountains, during a disaster or a power cut there is often no internet. Your team can send positions and alerts from Meshtastic radios. As soon as a message reaches a phone with internet, it shows up in Signalio.
For organizations and teams
Municipalities, volunteer groups, schools and companies publish alerts for their people and coordinate work in the field.
- Role-Based Teams
- Add members with owner, admin, or member roles to control who can publish alerts.
- Publishing rules
- You decide who publishes, whether alerts are public and who can see them.
- Targeted Alerts
- Create alerts with precise geographic areas so the right people receive them.
Campaigns on a shared map
When an alert turns into an operation, such as a fire, a search or a disaster, the organization runs it on one live map.
- Action zones. Draw the containment area or search sectors and assign them to individual teams.
- Team tracking. See the positions of volunteers and devices in the field in real time as they move.
- Field markers and reports. Participants mark findings, hazards and key points right on the map for everyone.
- Share with a link. Share the map with partners and volunteers via a link, even if they have no account.
