balenaSense - not parsing data correctly

Project help

I have no data in my balenaSense instance. It would appear that the sensor is being detected ok, but that there’s a math error going on:

Hi, can you give us a bit more information about your setup? Which hardware are you using? When you say the sensor “is being detected ok”, what commands are you using to confirm this? Are you running the latest release of the project from https://github.com/balenalabs/balena-sense?

Never mind: brainfart.

Had the wrong sensor plugged into the Breakout Garden.

All is well.

Thanks for letting us know!
