Hi all,

I’m doing a project with LoRaWAN and I’m using influxdb to save my data. Every sensor has his deveui as an identificator. I want to change this identificator by a name to know which sensor is it. Like the sensor with deveui 43840303 change to MyHouseSensor. Is it posible to do it in influx?

Thank you,  
Roger.

Hello @perico_smith ,  
Welcome!  
Have you taken a look at the rename processor plugin or the execd processor plugin?

Both are useful tools!
