Extracting json data

General

Hi

I am receiving json mqtt data in the following format.
I have to decipher what the registers mean.
I think the 2 I am interested in are the registers in bold
How can I extract those registers into 2 payloads?

{"elecMtr":{"0702":{"03":{"01":"00000001","04":"00","02":"000003E8","07":"2200015007642","03":"FB","08":"","00":"00","06":"00"},"00":{"07":"00000000","01":"000000000002","00":"00000017AB42","14":"02","02":"000000000000"},"04":{"01":"000845","03":"027E91","00":"00000112","02":"00810E"},"02":{"00":"00"}},"0708":{"01":{"01":"?????

Hi @Ian

this page in the docs explains how you can understand the structure of a message and find the path to any of its elements using the Debug sidebar: https://nodered.org/docs/user-guide/messages
