In the thread [Ras Pi voltage - new node.](https://discourse.nodered.org/t/ras-pi-supply-voltage/8791/62)

I wrote a little flow to play with it and show you what it can do.

For me, I don't mind data, but I don't like getting the same data over and over.

So I want to _differentiate_ it to only show changes.

I've played with the `RBE` node, but not had desirable results.

Anyway, here is the flow. I uploaded it to the library I hope.

But here it is just to show you all the functions it (the new node) can do.

This is a new tab/flow.

```

The source node `pulse` provides a . . . . clock to run the flow. Though you can use what ever you want.

The next two `inject` nodes select how the rest of the flow works.  
1 - ALL  
This sends all messages through.  
2 - CHANGE ONLY  
This only passes a message if there is a change from the previous one.

the output is for now a `debug` node.

I would inject that into a `list` of some sorts. Up to you.  
This simply shows you the output of the node and gives you a _list_ of sorts.

Enjoy.

Hi Andrew,

I have imported your flow and I see that the below checkbox is unselected:

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/7/712ccea60b67b748de61d67c3b170c4fa41aa6ef.png)

So the `msg.payload` contains a Javascript object which contains in turn **all** the data. And further on in the flow a Split-node is used to create separate messages. Isn't it easier to select the checkbox and use the RBE node (which can operate topic-based) to skip unchanged data?

> [@BartButenaers](#):

> and use the RBE node

I've tried using it in the past with that understanding.

But things weren't always happening as I wanted. After a lot of time I realised it is/was the `RBE` node.

Say it is in a flow and gets a message: `0000`.  
It passes the message.  
The message changes in the next pass to `0001`  
Again: It is passed.  
Next time it is unchanged and is blocked. Good.  
It changes again to `0010`, and is passed.

THEN!

It goes back to `0000`

It is blocked because it was `0000` the first time.

That was driving me crazy for weeks. So now I just don't use it because if the topic is not also changing it blocks messages I want to pass.

Maybe I am mistaken, but that is how I remember the problem.

The RBE node only holds one previous value for each topic so unless you were using multiple topics the situation you describe won’t happen.

Ok. Thanks. I really liked using the `RBE` node but one day _something_ happened and it was not doing what I wanted, which was simply blocking consecutive same messages.

The only thing I like with my `RBE` node, is that it can be turned on and off. 😉

Here is a nicer looking flow.

It shows the results with "lights" on the dashboard.

Ok, one of them doesn't work. Not sure why.

But I am sure someone can work it out.

Ok, oops.

It did work. Now it isn't.

The `switch` node is set to look at the `topic` and split per that.

But looking at it now, it is more the `msg.payload.x`.

But how do I _split_ that?

I have tried this:

```auto
[{"id":"8b5df135.2053b8","type":"switch","z":"2555a6cd.48e7ca","name":"","property":"payload","propertyType":"msg","rules":[{"t":"cont","v":"underVoltage","vt":"str"},{"t":"cont","v":"frequencyCapped","vt":"str"},{"t":"cont","v":"throttled","vt":"str"},{"t":"cont","v":"softTempLimit","vt":"str"},{"t":"cont","v":"underVoltageOccurred","vt":"str"},{"t":"cont","v":"frequencyCappedOccurred","vt":"str"},{"t":"cont","v":"throttledOccurred","vt":"str"},{"t":"cont","v":"softTempLimitOccurred","vt":"str"}],"checkall":"true","repair":false,"outputs":8,"x":370,"y":1490,"wires":[["62f7c81e.fa7bb","ce7492d0.f052f"],["d1687677.615bc"],["b534cb28.33b3d8"],["85adae52.70c018"],["efff0b79.51b09"],["a7b5e6d6.139a4"],["b5ac0d87.bcdea"],["3b09340c.3f726c"]]}]

```

But it isn't working because . . . . . ?

I don't know.

Sorry folk for saying it was a nice flow.  
(stuff happens.)
