Setting a value to 0

[Becker]

Hi,
I want to disable one of my inverters.
If I do, the values freeze.
I want to set them to "0".
But I don´t get a "0", always error or "undefined".

I just want to override with a "0" after disabling the inverter / last value freeze:

Can you please tell me how?

thanks

Hi!

There is a "change" node. You can use it to "set" a certain value of the msg "to" the desired value (number 0).

In german the translations for the settings are: "Festlegen" msg.property "bis" 0.

That error - PAC W: msg.payload: undefined - shows you (most likely ) have a error in the function node, but with out the flow, no one is going to be able to help you.

[Becker]

yes, the function node expects an object (msg.playload.PAC3)
