This issue is for discussing the data policy regarding cleaning the database from stale sensors.
The idea is to remove the sensors that was created just for experimenting, Some data are not valuable, such as sensors created from the dashboard but without any data and sensors created for a hackathon.
Possible policies for deleting stale/unused sensors:
sensors without data: delete 1 month after creation
guest sensors: delete after 6 month (?)
For 1., a sensor without any data is never valuable as it is easy too re-create. So it is safe to delete.
For 2., guest sensors are created by unconfigured/default gateways. I'm not sure we should delete them because the data might still be valuable. E.g. Waziup pilots are still using guest account right now.
