How can I split a MQTT string

Developing Nodes

Hallo,

i'm back from the hospital,

Now i can copy the MQTT message :

{ Time: "2022-02-02T19:39:51", DS18B20-1: object, DS18B20-2: object, TempUnit: "C" }

an split:

...............

object

Time: "2022-02-02T19:39:51"
DS18B20-1: object
Id: "03168C0093FF"
Temperature: 47.8

DS18B20-2: object
Id: "03168C212DFF"
Temperature: 46.7

TempUnit: "C"

..................

I like to extract the temperature from DS188B20-1 an from DB18B20-2 plus the time oft the
measurement.

Attached is my previous attempt

Can you help me to eliminate the correct values?
