Hello,

in the past I used a script to extract a value to a user object.

But it is easier than expected if using the converter funktion for an alias.

For example I need the acin power of my victron battery inverter but the mqtt values is a simple json:

{"value":970}

So I created an alias to this object and use in the alias declaration the function to grab the valiue.

JSON.parse(val)['value']

Cheers

For full safety I would recommend to remove all write capabilities from aliases pointing to JSON structures.
