Verify Sensor Status
Use the Sensors page and the details panel to confirm that Grillo Cloud is receiving data from a sensor.
Statuses
| Status | Meaning |
|---|---|
| Online | A health report arrived in the last 2.5 minutes and every check passes |
| Degraded | The sensor is reporting, but something needs attention: Weak signal (below -95 dBm), Clock offset (more than 50 ms), or Data arriving late (more than 2 seconds) |
| Offline | No health report in the last 2.5 minutes. The reason says since when, for example No data since 14:05 or No data for 3 d |
| Disabled | Reserved for sensors taken out of service on purpose. No sensor shows this status yet |
A sensor that has never reported shows Offline with No data received.
If Grillo Cloud itself cannot fetch new sensor data, a warning at the top of the page says since when, and statuses stay as they were rather than turning offline.
Checklist after setup or maintenance
- Open Sensors and search for the station code.
- Confirm it is Online, or Degraded with a reason you expect.
- Open its details and check Last 24 h shows recent data.
- Check Signal, Power, and Time sync.
- Confirm the coordinates and the firmware version.
To prove seismic data is arriving too:
- Continuous sensors: select Show live signal and tap the enclosure lightly. The trace should respond.
- Triggered sensors: tap the side of the enclosure firmly enough to cross the threshold. A new trigger appears on cloud.grillo.io/triggers within about a minute.
If a sensor is offline
- Confirm the Device ID is correct.
- Check that the sensor has power from its supply: 9–16 V DC for Grillo Pulse, USB-C for Grillo One.
- Check the connection for its variant: Ethernet link, Wi-Fi, or cellular service and SIM.
- Ask the site's network administrator whether outbound UDP is allowed. Sensors send to Grillo on UDP ports 5683 and 5684.
- Give the sensor a few minutes to start and connect.
- Look at Last 24 h and Last 30 days in its details to see when it last reported and whether it has been dropping out.
- Contact support with the Device ID, last-seen time, power arrangement, connection type, and screenshots.
If a sensor is degraded
- Weak signal: move the antenna or the sensor, or use an external antenna.
- Clock offset: the sensor cannot keep accurate time. Check that it has a working internet connection; if it persists, contact support.
- Data arriving late: the connection is slow or congested. Check the signal, or move to Ethernet where possible.
