Do we have an option to know an indoor room temperature via WyzeApp without Home Monitoring System, just CamPlus?

BTW, I don’t need a thermostat. I just want to know a few rooms temperature during winter so I can bring my pets to heated rooms as needed.

CamPlus doesn’t have any temp sensors. You would need the Wyze sensors for temperature, plus a hub. Be aware there are two temp sensors and one type only works with the thermostat.
