Edit log files ( delete wrong measurement for temp. sensors )

Votes:

0

Hello!

I monitoring temperature on my wood stove with arduino, and sometimes it happens that the sensor shows the wrong temperature (-127 C )

I know that the value can be filtered by spike filter and axis scaling, but I really want to delete all values -127C...
I try edit Log Database, ( with DB Browser for SQLite 3.10.1 ) , but database is encryptet with password....

How can I erase false measurements?

Thankyou for your help !

How exactly are you polling the Arduino? What sensor are you using?

Data that has been collected by PRTG cannot be deleted, the monitoring database folders are also proprietary and can't be read/modified. If you wish to "start over", deploy the sensor anew, it's history will be "clean". But the correct approach here is indeed to use the Spike Filter to disregard values below -100 for instance.

The data will still be in the database, but when graph and tables are rendered, these readings will be left out.
