Registering a sensor in an TTN application via API

End Devices (Nodes)
33

OK, bit of boring debugging later and I found the culprit by comparing the Python JSON to the PHP JSON:

$data3 = [
‘end_device’ => [
‘multicate’ => False,

mulitcate should be multicast

and

‘field_mask’ => [
‘path’ => [

path should be paths

Here’s the whole lot, partial reworked as the use of data1, data2 etc is banned under the Geneva Convention:

Will do some more tidying up and put this in to a repro
