GPS Data Conversion to Tago Location Format

GPS Data Conversion to Tago Location Format

Hi All,

I'm really struggling to work out how to get my device data to process into a bucket.
I've managed to narrow it down to the GPS data, which comes in from Helium having been decoded with the CayenneLPP decoder

{ "variable": "1", "value": { "altitude": 46.63, "latitude": 56.1503, "longitude": -3.0979 }, "group": "1678662693494" },

How do I correct this to the accepted format for "location"? I'm pretty stumped with this one :-)
Thanks,
Mark
