Installing and updating SensorGnome software

One of the first steps in troubleshooting is to ensure that you have the most up-to-date software installed on your SensorGnome. Aside from ensuring your SG is up-to-date – this entire guide as based on the premise that you are using the most recent software – reinstalling the most recent software can resolve many issues.

Raspberry Pi SensorGnome

For Raspberry Pi SensorGnomes, the software runs entirely off the MicroSD card; if the proper software isn’t present on the MicroSD card, the RPi SG won’t function properly. This can cause issues for teams who are unaware of this – and who expect to be able to simply swap out one card without ensuring that the new card has the proper software on it. But it also makes updating the software with a clean installation very simple; all you need to do is copy the software files onto a blank SD card.

Certain SD cards models have failed when running on Rasperry Pis. To reduce the likelihood of an SD card failure, try to use an SD card from this list of known models.

Always ensure that the MicroSD card you use with an RPi SG has the software copied onto it. The RPi SG runs exclusively from the software SD card, so if a blank SD card is used, the SG won't record any data (though you may still still lights flashing on the RPi).

1) Download the most recent Raspberry Pi SG software. Currently this is the October 12, 2018 version.

  • Direct download link: SGPI-2018-10-12_LIWIXI.ZIP

  • This is a compressed .zip file which will need to be “unzipped” prior to use. Most modern computers come equipped with the ability to handle .zip files.

2) Insert a blank or recently formatted MicroSD into your computer.

3) Copy the entire contents of the .zip over to the root level of MicroSD card. After copying over, the contents of the MicroSD card should look like the image below

4) Copy the contents of the .zip file to the root level of the MicroSD card

5) You can now insert the MicroSD card into the slot in the RPi. Once the MicroSD card is in place, power up the RPi and proceed to connect to it and check the Web Interface.
