Yes, there is meant to be a temperature sensor in addition to the one already present inside the thermostat that uses the 2032 battery. The Honeywell THX9421R5021WW/U thermostat is compatible with wireless indoor sensors. You can set the system to monitor temperature at the thermostat or at the sensor location, or use an average of both to optimize comfort throughout the home. The thermostat can use up to 6 wireless indoor sensors. When multiple sensors are installed, the thermostat can monitor temperature and humidity in separate locations.

I've just replaced my THX9421R5021WW thermostat and it won't let me add the gateway device. How can I correct this?

I have been using the honeywell thx9421r5021 thermostat for over 5 years. I just got a new cell phone and with the transfer I lost my username and password to access the thermostat via cell phone. How can I reset my username and password?
