MQTT Send Error: Object of type ElkRPStatus is not JSON serializable

Code must be printing this somewhere?

That's coming from the interface.py send() method. It does a try/except around the mqttc.publish() call and it looks like the json.dumps() for the message that's being passed into send is failing.

It can't convert ElkRPStatus into a string.
