I don't know if this is possible, from a design conventions point of view, but it would be nice, that in case of selecting "Json parsed object" to be able to specify a sub-level for retrieval.
I'll explain: Most of the consumer and PV devices I work with publish their payloads as: `{value: 240.5}`, for example.
If one could tell the node to get the `value` property of the payload, it would simplify the flow, saving a repeating change node.
What do you think?

Sounds like a great job for a change node. Let mqtt nodes deal with mqtt and change nodes change messages. 😁

I think that all\* nodes that receive input should let you consume `msg.payload.value` (or whatever property of the message you desire)
Something Dave & I have discussed and mostly agreed on for core nodes \*where sensible.
A pattern I hope will catch on.

Thank you guys.
