Timer in Dashboard

README.md

A near online timer made in Dashboard. You can link it with any automation setup in NodeRED, deploy multiple timers and add schedules to your devices. You can customise the payload to suit your needs.

Instructions: You can read all set up instructions here

---

Features:

• Modular (as a subflow)
• Unlimited timers per device
• Supports “days of the week”
• works offline
• Dashboard interface
• One button reset

You will need the following nodes:

• node-red-dashboard
• node-red-contrib-schedex

---

Settings

• PayloadON payload message sent on ON action
• PayloadOFF payload message sent on OFF action
• TimerNumber timer ID (unique for each timer)

I don't know what happened to a post. I said I was a gluten for punishment.
Seems I am, I lost the post it seems.

There is still a problem. The sub-flow making a new copy of itself isn't helping.

I would suggest you inject the set after deployment node to have the inject after boot set also.
That gets things established better.

As I see it you have two parts: (As before - and still)
1 - the three nodes at the top that "set things up".
2 - the bigger flow which you say can be duplicated to multiple instances.

The thing is: it can't.
You don't have any where in the second part that sets the number for that part of the flow.

Pressing the inject node for the first 3 nodes, sets things up. You still haven't made it an auto inject at boot node.
Then the rest works for instance 1 of the nodes.
But if you make a second instance, it will only read #1's settings.

This is because in the bigger part in the function nodes you call it Timer1 - which is the default node (though not set up).
As soon as you get Timer2 and so on, all the function nodes read Timer1's settings.

You get stuck because though it is trapped on the flow, you can cheat and have the different instances on different sheets. But that goes against the idea of it being repeatable, and the advantage of storing things in the sub-flow's contexts.

See what you can do to fix that problem.

Won't break as Timer1 is always set

No it isn't.

It is only set if the initial 3 nodes are triggered.
Which is why I am saying it needs to have the inject once ticked.

(Trying to not flood this, but......)
I'll edit the post.

A way you could get around it is have something like this bit of code in all the function nodes:

if (msg.topic == "SETUP")
{
    context.se("TIMER",msg.payload);
    return;
}

var z = flow.get("Timer"+context.get("TIMER"));

At boot (which you seem to avoid like the plague) a message is sent to all the function nodes for that instance of the timer and it sets their timer number.

Then if you have a second instance, you would inject a message with a 2 as the payload. (Topic set as well.)

OK I see when I cornered myself now - darn! right it's 7am right now and I have been up all night I will fight with this with a fresh brain! Thanks for the brain lessons :)

That's intended actually.
as you have to configure the payloadON|OFF to match your preference

Ok, no problems.

Get a bit of rest and come back with a clear mind.

Thought!
Rather than sending the values to the sub-flow via the variables, why not send it in a msg?
Then you have everything you need from a dynamic message.

The on/off messages can be sent from the inject node.
(Well, probably more a change node loaded up with all those things, but.....)

With me?

So the node (in the sub-flow) would look like this: (example structure)

//  Old code
//var x = env.get("TimerNumber"); 
//var y = env.get("PayloadON"); 
//var z = env.get("PayloadOFF"); 

//  New code
var x = msg.payload.TimerNumber;
var y = msg.paylaod.PayloadON;
var z = msg.payload.PayloadOFF;

flow.set("$parent.Timer"+x, x);
flow.set("$parent.Payload"+x+"_on", y);
flow.set("$parent.Payload"+x+"_off", z);

msg.payload = "Your timer " + x + " has been set";

return msg;

However, I guess the way I suggested is not for persistent variables, which you are setting. So sorry.

I was thinking - and I have been told that is dangerous - however.

I am just curious to the advantage of doing things this way.

The nodes all need to be connected together anyway - now (in retrospect) - to assign their timer number.

So you are feeding their data into a sub-flow that sets things in/on the parent flow's context.

All that could be done at the parent level anyway with the function node you have as a sub-flow in the flow and setting the flow context data there and then, rather than sending the message into a subflow that then sets the parent's context values.

Seems a bit redundant how you are doing it.

Just saying.

I will see what I can do with that info.
I have a couple of things to go through before I can get back to this flow. Now sure if you tried the beta3 for nodeRED - there are promising modifications to the function node that work on deployment. Something tells me I will be using that moving forward instead. Just need to get more familiar with it

Latest code better.
Not perfect though. Sorry.
