Update Sensor Firmware
:::note Handled by Grillo Support for now The new Grillo Cloud dashboard does not yet have a way to start a firmware update. Until it does, contact Grillo Support with the Device ID and the target version, and Grillo will make the change for you. The steps below describe the previous dashboard. :::
Grillo Cloud can update a sensor's firmware over the air (OTA). You choose a target version, and the sensor downloads and installs it the next time it checks in.
Only project owners and admins can start an update.
Which sensors support OTA
| Sensor | OTA from Grillo Cloud |
|---|---|
| Grillo Pulse on firmware 1.x | Yes |
| Grillo One | Yes |
| Current Grillo Pulse, Cellular and Ethernet (firmware 2.x) | Not yet. Grillo updates these units for you; contact support. |
The sensor's current version is in the Firmware column of the sensor table.
Before you update
- The sensor must be online. An offline sensor takes the update when it next connects.
- Make sure it has stable power. Do not unplug it during the update.
- On a cellular sensor, check that signal strength is steady. The download uses the sensor's data connection.
- Update one sensor first and confirm it comes back before updating the rest.
Start an update
- Open Sensors and select the sensor.
- Select Edit.
- In Firmware Version, choose the target version. The list shows the versions published for that sensor type; the installed one is marked current.
- Select Update Device.
- In Confirm OTA Version Update, select Confirm Update.
The sensor receives the target version at its next health check-in, about a minute later. It downloads the firmware, installs it, and restarts.
Check the result
Wait a few minutes, then refresh Sensors. The update worked when:
- The sensor is online again, and
- The Firmware column shows the target version.
The sensor also restarts, which resets Up since boot in its details.
If the update does not complete
- Firmware column unchanged and sensor online: the sensor may still be downloading, especially on a weak cellular link. Give it more time before trying again.
- Sensor offline after the update: check power and connectivity on site, then follow the troubleshooting guide for the sensor.
- Still on the old version after an hour: contact support with the Device ID, the current and target versions, and the time you started the update.
You cannot set the target to the version the sensor already runs.
