General
1

Hi i am a beginner in nodered, I would like to combine a text and a payload in a message to create an webos lgtv alert notification, i want to change "message":"Just Testing" with "message":"Just Testing & {{payload}}", node used is node-red-contrib-lgtv

msg.payload {"title":"Test Message","message":"Just Testing","isSysReq":true,"modal":true,"buttons":[{"label":"Dismiss"}]}
msg.topic ssap://system.notifications/createAlert

Thanks in advance and sorry if I wrote something wrong

You can apply the message items like payload and topic in a template node. This would entail putting these text values to the message parts into the same message then input to the template.

Thanks for the answer, I do not know if I understand well, I tried to create a template something is not right

so I understand that it is not possible

I am sure it is possible!

I don't really understand this:

i want to change "message":"Just Testing" with "message":"Just Testing & {{payload}}",
msg.payload {"title":"Test Message","message":"Just Testing","isSysReq":true,"modal":true,"buttons":[{"label":"Dismiss"}]}

What is in msg.payload before you do the join?
How do you want it to look after the join?

  1. msg.payload = {"title":"Test Message","message":"Just Testing","isSysReq":true,"modal":true,"buttons":[{"label":"Dismiss"}]}
  2. I want to enter the value of a temperature sensor in this message - "message":"Just Testing"
    2.1 the payload value is 22
  3. the output will be "message":"Just Testing 22 Celsius degrees"

I managed to solve the problem in the end, instead of the function I used the switch node, I hope to help someone else
