Thank you
Hello
Can someone help me see why the case that compares these strings does not work for me?
Thank you
Your arrowed debug is showing what is in msg.payload
not msg.payload.Modo_Operativo
Add node.warn(msg.payload)
and node.warn(msg.payload.Modo_Operativo)
to your function you will see why this is happening.
Thank you very much for the help
I have tried what you tell me and now I get this error,
I have to install a module or have I put something wrong?
Thank you
Firstly, I dont know why you are setting var Modo
to the result of node.warn
. node.warn
is a debugging function.
Anyhow...
Do you see how msg.payload.Modo_Operativo
is reported as being undefined
?
Do you see how msg.payload
is reported as being "Modo_Auto"
?
Use msg.payload
instead of msg.payload.Modo_Operativo
in your function...
Please paste function code as text NOT as an image.
And always format code between 3 backticks
```
like this
```
Hi
Ok, that part already works for me !!!
Now I need to collect the value and match it to the variable depending on each case
You cannot use the payload from completely different message.
Either store the value that comes out of the other HA node in flow/global context then you can access it later on in the function node using flow.get
Or
Use a join node to join the 2 messages from the 2 HA nodes.
See this article in the cookbook for an example of how to join messages into one object.
There’s a great page in the docs that will explain how to use the debug panel to find the right path to any data item.
Pay particular attention to the part about the buttons that appear under your mouse pointer when you over hover a debug message property in the sidebar.
Hi
I have tried this function, but I guess I am missing something. It keeps appearing to me undefined.
thank you so much for help me
You need to grab the stored context value from flow
E.g...
var value = flow.get("xxx")
Where xxx
is your flow variable name.
I recommend you read the docs (linked above) particularly about function nodes.
Also, I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
Thanks a lot !!
With this advice I have already solved it.
I will follow your advice and watch the tutorial videos
Thank you so much for everything !!
