I am trying to get an SPG30 working but I am unable to. The rest of the modules in the chain show green lights and respond to I2C commands. This is the first module out of many that I have purchased from adafruit and Im really happy with the rest. I am unable to find any posts on what a red light means.

Can you get data from it when you connect it by itself? What processor are you doing to communicate with it?

the red LED on this board is normal (its a 1.8V not 3.3V sensor so we cnat use green)
we'll need to know more about the setup to debug!

Yep, it's just a power indicator LED. Red on some breakouts. Green on others others. For Reasons as stated above.

For the SGP30, it's the "ON LED" shown in the schematic:

For troubleshooting, an I2C scan can help as a simple sanity check that at least the SGP30 can be seen by the host controller:

The SGP30's address should be 0x58.

First of all Thank you so much for the response. You guys are awesome!

Also please let me thank you guys for keeping me sane during all the isolation. Being able to get my nerd on is an amazing distraction.

Isolating seemed to do the trick. I can now get it to respond.

This is actually a duplicate build of a climate monitoring system That I hadnt had time to 3D print the encloures for. Subsequently, I just strung them all together and stuck it outside while I worked on my code to connect them both to the same database. My conlcusion is that order seems to matter.

Thanks again!
