I am new to node red
I want to send WhatsApp message when the alarm change state
The payload that i get from the alarm device is
"{"payload":{"arm_state":"arming","detail":{"sid":2,"name":"Away Mode"}}}"

Thank you

You can use a filter node to only pass a message when msg.payload.arm_state changes

I don't understand "if it match" here.
Perhaps you need to set the filter node to handle each msg.payload.detail.name separately

payload.detail.name

thank you for your reply.

i was thinking about comparing the arm state with a value of arming and name with a value of away mode in the payload. then if what i am getting is true for both then send me whatsapp.

i think it is too complicated for me. i settle for checking the name to has a value or alarming from the payload message. i am using AND node like below

i hope there is a better way to extract a string value from the payload and compare it to any defined string value

thank you
