Just confirming @gjelsoe 's conclusion - while the sensor was added to protobufs, there is not any support for it in code at the moment.

I've added a patch that will make it detected: #6009

but it won't do anything until the full sensor support is added.

It should be stated in the docs that the LTR390 is still in development and not supported yet. I just bought one to figure out it's not implemented.
