Can remote room sensors actually solve hot and cold spots?

A common limitation with traditional thermostats is that they measure temperature from just one location, even though comfort can vary significantly between rooms.

We’ve been exploring this challenge while developing PCT5231, a smart HVAC thermostat that can work with up to 10 remote room sensors.

The idea is to provide better temperature visibility across multiple spaces instead of relying only on the temperature measured at the thermostat itself. This could be particularly useful in multi-room homes, apartments and other spaces where hot and cold spots are common.

We’re curious how others think about this:

Would you use multiple room sensors with a smart thermostat? And what matters most — averaging temperatures, prioritizing specific rooms, scheduling different sensors, or simply seeing room-by-room temperatures?

Would love to hear how you would approach it.
