How to use Adafruit MCP9600 I2C temp sensor?

I saw in the Custom Firmware Builder that a dedicated temperature sensor called MCP9600 can be activated as a build option. Since I like having many sensors and previously used additional baro(s) as temp sensors, this caught my attention. I have no experience with this type of sensor though, so a few questions arise:

  • I searched for MCP9600 and found out that the sensor can actually measure 2 different temps - its own and the one of a connected probe (K-type thermocouple). Can both be used?

  • Will the value(s) show up on OSD, and if yes, as which element?

Thanks in advance!
