Description

The LTR390V sensor is not identified. Protobuf supports it, but I2C does not identify it.
Its address is found at 0x53, see the log excerpt.

Seems there are made some preparation for this sensor but not finished yet.

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.

Please add support for a full weather station. Thank you

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.
