The easiest way to determine if a Bluetooth Thermometer was used to capture a temperature is to go to the Completed Report.
We track the source of every entry into the system. For Bluetooth Thermometer entries we put a little Thermometer icon next to them.
If you don't see the icon, like in the first answer above, that mean the response was hand entered.
FYI: We can add rules to your questions that require a comment if you don't use a thermometer. If you want to get that rule added to your platform, talk to your OpsAnalitica Administrator.
