Enable emonHub to subscribe to JSON MQTT topics, useful for integrating with zigbee2mqtt and Shelly WiFi sensors.
e.g
The above emonhub config subscribes to MQTT topic
zigbee2mqtt/tempand decodes the JSON message{"battery":100,"humidity":72.23,"linkquality":116,"temperature":21.79,"voltage":3000}which results in an input key calledtempand Inputs with battery, humidity etc.
