Unable to convert cell Id to lat lng

[akkharolia]

cell_id = 600090378170794000

the above cell is converted using h3-js successfully, in python it gives invalid cell ID error.
I tried with all function of h3-py i.e. api functions(basic_int, basic_str etc).

also found that python hex output is different from javascript output. So created below function to match the output.

def _hex(num):
rounded = int(float(num))
return hex(rounded)[2:].lower()

I'm using below function to convert to lat lng.
h3.cell_to_latlng

Still getting error of invalid cell ID.

Another Cell ID: 601803032887296000

h3-py version: 4.2.1

Can you share the code that generated the cell_id above? That is not a valid ID.

I am receiving this as H3CellId in starlink telemetry API streaming data.

It has been a while since I looked into Starlink, but as I recall, they don't use H3, but their own hex grid with a different ID system. If h3-js somehow parsed that ID you linked, that's a bug in h3-js, not in h3-py.

Even if I convert 600090378170794000 to hexadecimal, resulting in 853F30500000010 I can tell that it's invalid because there are too many digits and the ID doesn't end with trailing fs for unused resolutions.

Yes, that's my concern too. Passing the string in h3toGeo in h3-js gives lat,lng of the cell. Let me look for solutions for this in starlink docs.
