A Thermostat Room Sensor or a Standalone Room Thermometer?
If a room reading should influence a thermostat, start with a sensor that the exact thermostat supports. A standalone monitor is a different purchase when the goal is simply understanding comfort.

Separate viewing and control
A reading in an app tells you about one location. Using that reading in HVAC decisions requires a supported relationship with the thermostat and a configuration that reflects how the household occupies the rooms.
Choose the room deliberately
A bedroom that feels different from the hallway may justify a closer look. Discuss sensor placement and which periods matter, rather than assuming adding more sensors automatically makes every room equally comfortable.
Compare complete arrangements
Ask which sensor models work with the selected thermostat and what changes in scheduling or control will be made. Keep independent monitoring devices separate on the quote so their purpose stays clear.
