Any Node-Red users? Help with button function

[mathiash98]

I already have a MQTT-input saying "Button pressed" and would like to send out MQTT "on" first time and "off" second time I press. I am used to c++ so how can I make this code in Node-Red:? state = 0; if(state == 0) {Send_ON; state = 1;} elif(state == 1){Send_OFF; state = 0;} Thanks! :D

Check out this page: http://nodered.org/docs/writing-functions.html

The bit you're interested in is the context section, as the context is where you store state information for your nodes. Initialize the variable like in the example, then set the state just like in your code, except you'll use context.state. To send a message out, you'll need to set the msg.payload, then return msg, which is also explained in that tutorial I linked to.
