Convert one value into two different ones

[sfedo]

Hello guys,

I have a switch module from Hue. The module only ever gives me one value when I press it: "short_release". I now have to turn this value alternately into a 1 and a 0. How can I do this? Do i have to save the first state in node context or something like that?

You can send the value into a trigger node to output 1 then after a delay output 0.

I was thinking about it, but i need sometimes double click, so there is not much time for reset threw trigger.

It really helps if you give all the info. Please post all info and maybe a example flow with all possible inputs in separate inject nodes, then we can offer some suggestions.

I really dont know how to explain better:

1st message is I toggle the switch on and second is i toggle switch to off. I need this node to do so. Like i need some function i would write in javascript like this:

let status = false;
if (msg.payload.action=="short_release" && status == false){
    status = true;
    return msg.payload = 1;

}else if (msg.payload.action=="short_release" && status == true){
return msg.payload = 0;
}


return msg;

but i dont know how to store this variable "status" int othis function node, until msg.payload triggers it again. Thats my problem actually.

try

let status = context.get("status") || false;
if (msg.payload.action=="short_release" && status == false){
    status = true;
    msg.payload = 1;
}else{
    msg.payload = 0;
    status = false;
}
context.set("status", status);
return msg;

[sfedo]

great! it works as expected. Thank you!

Reading between the lines, if you want to handle different incoming button presses messages, then you would do something like this

let status = context.get("status") || {};
let presses = msg.payload.action
if (status[presses] == false){
    status[presses] = true;
    msg.payload.output = 1;
}else{
    msg.payload.output = 0;
    status[presses] = false;
}
context.set("status", status);
return msg;
