Getting value from MQTT message

[dforster]

Hello,

I am trying to retrieve the value for "accumEnergyTotal" in the image below so I can output this in the message payload. I have tried and tried and as yet not succeeded. Could someone help me please? Cheers Daniel

looks like msg.payload.states[2].accumEnergyTotal.value

There are buttons at the right hand side of the debug pane that let you copy an object's path. Very useful

J,

I tried this (see image below) but it still comes up with the full message.

Cheers - Daniel

Have you deployed the change?

Where is the debug connected in your flow (before/after the change node)?

[dforster]

Steve,

Thanks for coming back. Yes, all deployed. See images below. Dan

[jbudd]

That shouldn't happen!

Can you see what you get if you change the debug node to show the complete message?

[Steve-Mcl]

Did you use the copy path button - that path looks incorrect.

[jbudd]

oops my mistake, well spotted!

It doesn't explain why the whole payload is still there though.
If you set msg.payload to something that doesn't exist, it should become Undefined?

[dforster]

So if I use copy path beside the value I get this. payload.states[2].value

and if I use the copy path beside accumEnergyTotal I get this payload.states[2].name

[dforster]

Fixed it changed it to this 'msg.payload.states[2].value'

Many thanks to both you and J (in previous reply). Happy man now I can see how the utility is going to rip me off for power I buy... (40p + per kWh) - Dan
