Help: JSON to Temperature and Humidity Items

Add-ons Other
1

Hello,
Does anyone know how to extract the temperature and humidity values into their respective items in OpenHAB2 from an MQTT message?

The output from the device is as follows:

{“Time”:“2017-02-10T19:34:28”, “DHT”:{“Temperature”:“18.50”, “Humidity”:“61.10”}}

2

Use the JSONPATH transform.

:JSONPATH($.DHT.Temperature)
:JSONPATH($.DHT.Humidity)

Thanks @PointandClick

How would that actually work in the home.items file?
I currently have the following

Number RoomTemp “Temperature [%.1f °C]” (Temperature)
{mqtt="<[mqttbroker:home/roomone/DHT:state:default]"}

Will it be like this
{mqtt="<[mqttbroker:home/roomone/DHT:state:JSONPATH($.DHT.Temperature)]"}

That should be right.
