A few questions about the APP trends.
Device time: from where is it taken? Or, better, how is the device synchronized?
In the trend a temperature value is reported every 15 minutes, what is shown is the instantaneous value at the 15th minute or the average of the values over the 15 minutes?
In the APP I can find a record of data for each day, Where are that data stored, on the device or on the web? How many days will be kept?
Many thanks for your help.
