The 6332 will transmit Solar/UV (along with any other input signal, like Rain and T/H). Unfortunately, this is a console issue (OK, and regular Envoy). Solar and UV can only be read from an "ISS" as set in the console. It will ignore the Solar/UV if it is from the 6332. I went through this issue myself several years ago. I was forced to run an 85 foot cable from the solar sensor to the ISS, despite having the solar sensor being mounted close to the 6332. (for my current configuration, Sol/UV are back on the ISS)
All "SIM" (Sensor Interface Modules) whether the hinged-door or sliding cover enclosure types are the same. The label might indicate a Temp/Hum station, Temp station, Anemometer transmitter, etc. but they are all capable of sending data from the associated connector inputs. (RAIN, T/H, WIND, SOL, UV). I have a "Temperature Station" configured as an anemometer transmitter, and an "Anemometer Transmitter" set up as a rain station and temperature sensor. (this required the Meteobridge Pro for the "rain station".)
