Hey guys! New to node-red and im trying a new project using heater-control plugin.
I am trying to trigger my relay using the output topic currentHeaterStatus to a RPI GPIO pin with relay attached. My flow is attached below.
I am using a change node attached to the heater controller then outputting to the GPIO out.
I am trying to change "currentHeaterStatus=on" and "currentHeaterStatus=off" to control my relay. So I am trying to convert the "on" and "off" stings to boolean as true and false.
Running the change node.
Change >> msg.payload
search for >> String >> on
Replace with >> boolean >> true
Change >> msg.payload
search for >> String >> off
Replace with >> boolean >> false
It just throws the error
"Invalid input: NaN"
Please help ive been stuck on this for ages now.
Sorry if the formatting of this post is terrible.
