After reviewing the documentation and searching through closed issues, it appears that Thermal Comfort does not currently include a sensor for calculating the wet-bulb temperature.

The wet-bulb temperature is the lowest temperature achievable through evaporative cooling of a water-wetted, ventilated surface. Although the wet-bulb temperature (WBT) cannot be calculated exactly, an approximation is available. The most suitable equation for this purpose seems to be the one provided by Roland Stull, which yields reasonably accurate values up to 50°C.

For those interested in the details, the relevant paper can be found here:
https://open.library.ubc.ca/media/stream/pdf/52383/1.0041967/1.

Additionally, an example calculator using this equation is available here:
https://www.omnicalculator.com/physics/wet-bulb#how-to-calculate-the-wet-bulb-temperature.

Since Thermal Comfort already has access to all the relevant values needed to solve this equation, it should be feasible to integrate a wet-bulb temperature sensor into the framework.

I would love that feature, too!
