Hello @CeJay,
The bad request (400) is generated because the double quotation marks used in the request are not the proper ones.
Try the following request to handle your data with Ubidots:
curl -X POST -H "X-Auth-Token:BBFF-xxxxxxxxxxxxxxxxxxx" -H "Content-Type:application/json" -d '{"value": 59}' https://industrial.api.ubidots.com/api/v1.6/devices/mqttdata/number/values -vvv
Server response expected:
Note: Unnecessary use of -X or --request, POST is already inferred.
