I could use some help getting my function to operate correctly. Here is my setup so far: rpi gpio node set up as a button pin input, looking for 1 or 0...This is linked to the email node. You push the button and get an email. Email is sent successfully, but it sends a 1 or 0 depending on the state of the pin.
What I would like is a function node between my rpi gpio node and my email node. If button pin is HIGH/1, than send an email...If button pin is LOW/0, than do nothing.
Im really pretty good w/ Arduino IDE and coding, but rpi and Node-RED are very new to me. Im learning, but could use some help w/ this first example.
I appreciate any help you guys can give.
often you may not need a function... look at the switch node...
How would I set the switch node up to do what I need for it to do?
drop in you flow, double click it and look at its options
I got it! So now I have the switch between rpi gpio node and email node. I have the switch rule set to only send an email when the the value is == to 0. The email that was sent has pi/37 in the subject line and 0 in the body. How do i change the subject and body?
maybe use a change node...
look at the options on the email node to see what msg properties you can send into it.
That worked! msg.payload for the body and msg.topic for the subject line. I really appreciate you guys and your help!
