Fields

Field names match without regard to capitals, spaces or underscores, so Tyre _FR_ Temp and tyre_fr_temp both work.

Send timestamp as ISO 8601 with time zone, or Unix seconds or milliseconds, so data buffered on the SD card keeps its real time. To upload a buffer in one go, send a JSON array of packets.
