This orta do it (for future reference)

USE observium;
SELECT location_lat, location_lon FROM devices;
UPDATE devices SET location_lat = NULL WHERE location_lat IS NOT NULL;
UPDATE devices SET location_lon = NULL WHERE location_lon IS NOT NULL;

Thanks,

Modify the database and set the lat/lon to NULL for all devices and they'll
be re-set when they're re-polled, it's the quickest way.

We should include something in the UI to do this (and do a real-time lookup,
perhaps).
