Troubleshoot Grillo Pulse

Start with Grillo Cloud: it is the only way to check a Pulse from outside, because the status lights are inside the enclosure. Do not open, reset, or rewire the sensor unless Grillo Support asks you to.

Status lights​

Grillo Pulse has three status lights on its circuit board. They cannot be seen with the enclosure closed, so they are only useful if Grillo Support asks you to open it.

LightMeaning
Green onThe cellular or Ethernet connection is up
Red onThe connection failed. The sensor keeps retrying.
Green and red both offThe sensor is starting up or still connecting
White blinkingData is being sent. Each blink is a packet.

A healthy sensor shows green on and white blinking steadily.

Gather information​

Before contacting support, record:

  • Device ID, and whether it is Pulse Cellular or Pulse Ethernet
  • Firmware version shown in Grillo Cloud
  • Project and station code
  • Status and Last Seen in Grillo Cloud
  • Connection type and signal strength, if shown
  • Recent changes at the site: network, power, or moving the sensor
  • Photographs of the installation and the label

Sensor is missing from Grillo Cloud​

  1. Select the correct project in the project switcher.
  2. Search by Device ID and station code.
  3. Confirm the sensor was claimed.
  4. If Grillo Cloud says Device not found when you claim it, check the ID or scan the QR code. If it is still not found, contact support.

Sensor is offline​

  1. Check Last Seen and the sensor's connection history to see when it stopped reporting and whether it has been dropping out.
  2. Check the M12 power cable is connected and tightened, and that the 12 V DC supply or solar kit has power.
  3. Check the connection:
    • Pulse Cellular: check the cellular antenna is on the SMA cellular connector, and the mobile coverage at the site.
    • Pulse Ethernet: check the cable is fully seated through the weatherproof entry, that the port is live, and that the network gives out addresses by DHCP.
  4. Pulse Ethernet on a managed network: check that outbound UDP on ports 5683 and 5684 is allowed. Ask the network administrator.
  5. Restart the sensor: disconnect the M12 power cable, wait 30 seconds, and reconnect it.
  6. Give it up to 5 minutes (cellular) or 1 minute (Ethernet), then refresh Grillo Cloud.
  7. Contact support if it stays offline.

Location or station is wrong​

Open the sensor in Grillo Cloud, select Edit, correct the station code or location, and save. Physical orientation has to be fixed at the installation.

Noisy or implausible data​

  • If the geophone channel (EHZ) is flat or missing while the accelerometer channels look normal, check the geophone is plugged into its connector on the circuit board. See Pulse Quick Start.

  • Check that the enclosure is rigidly mounted, upright, and level.

  • Look for loose fixings, or cables touching or tugging the enclosure.

  • Note nearby machinery, traffic, wind, and people.

  • Check the outside of the enclosure for damage or signs of water getting in.

  • Contact support with installation photographs and the times you saw the problem.

Firmware updates and reset​

The current Grillo Pulse cannot be updated from Grillo Cloud yet; Grillo updates it for you. See Update Firmware.

Do not open the enclosure, connect USB, or attempt a factory reset unless Grillo Support asks you to.
