Remove old data?


#1

Hi I got my Marvin Board from http://www.rdmmakerspace.nl/marvin/) up and running

first time I tried Cayenne following this intuitive guide https://www.thethingsnetwork.org/labs/story/tutorial-microchip-lora-mote-and-the-things-network-cayenne-integration I used a hard coded data field: lpp.addBarometricPressure(2, 1073.21);
along one coming from reading temperature: lpp.addTemperature(1, t);

Now that I removed lpp.addBarometricPressure(2, 1073.21); and added lpp.addRelativeHumidity(2,h); the Humidity data are read into the prevoius barometric field


The hardcoded pressure data 1073.21 Pa is still available.
Is it possible to delete that ? or
do I need to read lpp.addRelativeHumidity(3,h); with index changed from 2 to 3 ?
or am I required to delete the device and start over again?

Thx

The only way I know to delete it is to delete the widget and re-add, but that will delete all data.
