Node-RED as Alternative Rule Engine

[JGKK (Johannes)]

Just adapt for as many outputs as you want, you have to choose how many below the text input of the function node, for this example 2. When the first if is true it returns the payload on output 1 and if the second one is true on number 2.

var channel = msg.payload.channel;
var event = msg.payload.event;
if (channel === "triggerChannelyourlookingfor1" && event === "eventyourlookingfor1") {
    return [msg, null];
}
if (channel === "triggerChannelyourlookingfor2" && event === "eventyourlookingfor2") {
    return [null, msg];
}
return null;

That’s truly fabulous

Thank you so much

I’ll post my working statement for others to work from.

Cheers
Stuart

UPDATE

So the && (AND Condition) in the IF statements didn’t work for me, but with a switch node after the IF Function, I can see the three different states from the Velbus buttons.

The premis is that there are Virtual switches in openHAB2 that can be set in the UI or Voice Commands etc

Each Scene switches OFF the other scene switches and set out ITEM states.

There are Feedback LEDs that can have their state changed.

Here is the Flow code for anyone that is interested.
(I’ve removed the actual items and openHAB controller, so you’ll need to tweak each node to suit your installation)

Please feel free to advise / revise this flow, as this is my First venture into NodeRed

That’s a full rule to toggle all outdoor Sonoffs that control lights to turn ON/OFF when a Xiamio is pressed, double pressed, long press or long release.

May approach would be mostly the same, assign a “virtual” item like

v_Switch_Outdoor_Xiaomi_VirtualSwitch_shortpress
v_Switch_Outdoor_Xiaomi_VirtualSwitch_doublepress
v_Switch_Outdoor_Xiaomi_VirtualSwitch_longpress
v_Switch_Outdoor_Xiaomi_VirtualSwitch_longrelease

and use these “virtual” items in Node-RED

Can you show me your your function node? Just tested it in my setup. I have a 4way RockerSwitch with 1 Channel per side and this function node returns one of the possible events on each output no problem.

var channel = msg.payload.channel;
var event = msg.payload.event;
if (channel === "enocean:rockerSwitch:FT2VDC6O:FEF9093C:rockerswitchA" && event === "DIR1_PRESSED") {
    return [msg, null, null, null];
}
if (channel === "enocean:rockerSwitch:FT2VDC6O:FEF9093C:rockerswitchA" && event === "DIR2_PRESSED") {
    return [null, msg, null, null];
}
if (channel === "enocean:rockerSwitch:FT2VDC6O:FEF9093C:rockerswitchB" && event === "DIR1_PRESSED") {
    return [null, null, msg, null];
}
if (channel === "enocean:rockerSwitch:FT2VDC6O:FEF9093C:rockerswitchB" && event === "DIR2_PRESSED") {
    return [null, null, null, msg];
}
return null;

you can see the the events beeing sorted to each output, for example here the highlighted event came rightly through output number 3

here is the function node

Hi

Thanks for the help

This is the text I have in the function I’m playing around with.

var event = msg.payload.event;
var channel = msg.payload.channel;
var button = "velbus:vmbgp2:c5053467:24:input#CH3";

var newMsg = { payload: msg.payload.event };

if (channel === button) {
 return [newMsg]; }


if (channel === button && event === "PRESSED") {

return [newMsg];
}

If (channel === button && event === "LONG_PRESSED") {

return [newMsg];
}

if (channel === button && event === "RELEASED") {
 return [newMsg];
}

return null;

And these are definately the events I’m trying to match

{ event: "PRESSED", channel: "velbus:vmbgp2:c5053467:24:input#CH3" }

{ event: "LONG_PRESSED", channel: "velbus:vmbgp2:c5053467:24:input#CH3" }


{ event: "RELEASED", channel: "velbus:vmbgp2:c5053467:24:input#CH3" }

Comparing to the IF statement you’ve posted, I seem to be missing a bunch of null

Would this be better?

var event = msg.payload.event;
var channel = msg.payload.channel;
var button = "velbus:vmbgp2:c5053467:24:input#CH3";
var newMsg = { payload: msg.payload.event };

if (channel === button) { return [newMsg, null, null, null];
}

if (channel === button && event === "PRESSED") { return [null, newMsg, null, null];
}

If (channel === button && event === "LONG_PRESSED") { return [null, null, newMsg, null];
}

 if (channel === button && event === "RELEASED") {
return [null, null, null, newMsg];
}
return null;

So much info here . Just adding tutorial on Telegram to the mix. Do hope it helps others.

Tutorial on Telegram and Node Red - Interact with OpenHab

I had been looking for a solution where I could have my home automation system send me messages and process any feedback. Came across Telegram a couple of days ago by accident. Noticed also that the binding for openhab was V1 so didn’t explore much further on it. Then that Node-Red has a great node for interacting with Telegram and I am using a combination of Open-Hab/Node-Red. Love the combo as it makes building and testing flow easier - that is another topic. Anyway, it turned out to be …

[JGKK (Johannes)]

Try it like this. If I get you right you dont actually need four but only three outputs on your function node. One for each case. Another question is do actually need the released event even? Else eve 2 would be enough.

var event = msg.payload.event;
var channel = msg.payload.channel;
if  (channel === "velbus:vmbgp2:c5053467:24:input#CH3")  {
	if (event === "PRESSED") {
		return [msg, null, null];
	}
	if (event === "LONG_PRESSED") {
		return [null, msg, null];
	}
	if (event === "RELEASED") {
		return [null, null, msg];
	}
}
return null;

Hi

Thanks for your help.

There is a good use case for including the RELEASED events into this logic, as there are some situations where an action is needed when the button / input is pressed and another when it is released.

For example…

Start on Press
Stop on Release

What I am trying to create is a Generic Solution that I can save in a library and adapt for real world flows.

It looks like I can use either solution, but I can’t use both in the same IF Function.

These are the solutions I have running.

The IF statement is this

var event = msg.payload.event;
var channel = msg.payload.channel;
var newMsg = { payload: msg.payload.event };
var button = "velbus:vmbgp2:c5053467:24:input#CH1"

if  (channel === button )  {
	if (event === "PRESSED") {
		return [newMsg, null, null];
	}
	if (event === "LONG_PRESSED") {
		return [null, newMsg, null];
	}
	if (event === "RELEASED") {
		return [null, null, newMsg];
	}
}
return null;

The version with the IF Function to filter the button and a Switch to filter the button states, then with some triggers to reset the Debugs so that new events can be seen in the Flow, looks like this

The IF Function is simply this

var channel = msg.payload.channel;
var button = "velbus:vmbgp2:c5053467:24:input#CH1";
var newMsg = { payload: msg.payload.event };

if (channel === button) {

Sorry for stupid question, what is the difference in nodes:
node-red-contrib-openhab2 & node-red-contrib-openhab-v2

[JGKK (Johannes)]

I think everybody here is using the node-red-contrib-openhab2. It’s also the one beeing more actively maintained. The other one might be a fork.

[cybix32 (Peter Svensson)]

node-red-contrib-openhab-v2

That was a really good question. I have used both of them a couple of weeks and decided to go with node-red-contrib-openhab-v2. I hope that wasnt a mistake.

They are very similar, but a couple of smalls differences:
node-red-contrib-openhab-v2
Does have a few more configurations, for example, “Event types”
It does miss an output, so you can use the out-node and continue to wire another node

But, as a I see it, really small differences.

Hi there!

I use a simple switch node for filtering the events I want from the Openhab2 events node…

Like this…

This way I didn’t have to create a complex function node.

In the image I’m using the same switch node to extract data from 3 different Xiaomi wall switches.

[NCO (E. Gerland)]

Just a short question.
Rule engine is the regular text based rule files, not the experimental rule engine in PaperUI?

If so,
Your tutorial is the one I was looking for.
Migrating all my rules will take a while but node red sounds awesome.

Thanks for sharing.

Hi

I meant to post about a NodeRed scheduler I found here, but put it into another NodeRed thread by mistake.

Node-RED as a rule/script engine for openHAB

I know that Scheduling is the holy grail that we all seek, so imagine my delight in finding this node Now we / I just need to create some kind of way to put it into a GUI Does anyone have any ideas how we can put the scheduling variables into a UI like this?

[bummzulu (Martin)]

Thanks for this post. Nodered is absolutely awesome. I migrated most of my rules already. Once I have grasped the concept the migration was extremely fast and the rules are even more reliable now.

@Kai - Nodered should be considered as standard rule engine for the next major openhab release.

[vzorglub (Vincent Regaud)]

@bummzulu
Node-Red is great and very useful as it has a number of integrations not available in openHAB.
Things like scheduling and heating control are easier to achieve

BUT node-red has great limitations too…
How do you check the state of an item INSIDE a function node for example?
How do you create a rule with a trigger like Member of gGroup changed ?

Very useful but not sufficient for a full home automation engine without serious fiddling

[JGKK (Johannes)]

Actually both can be achieved over the rest api of openhab. You can for example create a sub flow that internally polls openhab regularly or just on deploy for the members of a group and updates a flow variable in the sub flow accordingly. This Array in the variable you can than use to filter an sse event stream from openhab. If you put both in a sub flow and use an environmental variable to construct the URL you have a reusable node where you just have to enter group name and you get any events inside that group. As for using the state of something inside a function, I either split it and use an http request in the midle to get the state. Or for item states I use alot I write them to flow or global variables on any change. The only trigger I haven’t been able to replicate is received update.
But yes their will always be the same limitations that everything else that communicates over the rest api or mqtt has. The internal Rule engine just has a deeper integration.
Best regards Johannes

[vzorglub (Vincent Regaud)]

As I said, serious fiddling

[JGKK (Johannes)]

Thats what makes it fun Especially in Nodered it’s so quick and rewarding to build/automate stuff and my description makes it sound more complicated than it really is.

[bummzulu (Martin)]

I use a flow or global variable to check the item state within a function node. That is no fiddling for me.

Checking the group events might be more tricky but I have not used that so far.

I don’t want to bitch about openhab. I love it and it is the only open source project so far that convinced me to donate money regularly. Just wanted to point out that the great developer team might save time on developing as some really good solutions are already out there and they can focus on even more innovative things for the nexts major release.
