Hi,

I have problems with the Grove I2C multichannel gas sensor and I hope you can help me.

This sensor is on port 0x04, so not compatible with grovepi unless you load an alternate firmware
I don’t know where the alternate firmware is. Can you guide me? If it works, I will update the tutorial to our wiki.

Best Regards,

Even though that article is actually meant for stacking multiple GrovePis, I think you could get away with it for this particular issue.

Just so you know, here’s the folder that’s being referenced in that article:

Thank you!
