This is good work. I think the problem you’ll have is that those tokens will expire. If you paste them into the debugger at http://jwt.io you’ll find an “exp” unix timestamp.
I think what this needs is a full integration as it needs to call a few endpoints in sequence to get the tokens.
You’ll also notice that in the commands/v1/appliance response it lists MQTT endpoints. But I just can’t figure out how to connect to them…
