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.
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.

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.

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.
@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

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.

As I said, serious fiddling

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.
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.
Nodered is already included as an option in Openhabian were it comes ready with the Openhab nodes installed. That is as far as integration will go I’m afraid. I’m a big fan of Nodered and use it a lot but I can see the need for openhab to be an all in one Self sustained solution and Nodered can never become part of that as it is completely independent project which is outside of the control of the openHAB project. So it would create unnecessary dependency on another project. So I guess we will have to live with the limitations of the Rest api for now.

+1 for Node Red!!!
its the best thing that can happen to noobs all over the world 
but serusily , i was able to do some seruis workarounds with node-red, i am not sure OH is that
flexible , in node-red you can get things worng and still make it wrok
also its alwys good to have another way of doing things, when all goes bad

Hi All
A happy new year to everyone
Something has been bugging me for a while, so I have spent an hour finding a solution.
What I wanted to do was mimic the Press and Hold dimming / volume change that you might see in some hardware.
I found a way to detect a button event, get the current Item state (a number) and add or subtract a number then inject the new value back into the Volume or Dimmer Item.
This worked well, I had 2 buttons.
1 for up
1 for down
I could even use the Long_Press and Release states from these buttons to loop the trigger so that holding the button down kept on having an effect, until the button was released.
What I wanted to do was reduce this down to 1 button, that would increase the volume (or brightness) until a limit was hit, then decrease until another limit was hit.
I found the solution by using a Global Value in Node Red.
Here is what I have running now in a Function node 
var volume = Number(msg.payload.state);
var button = String(msg.payload_in);
var newMsg = { payload:button};
var Dir = global.get("LoungeDir");
var newVolume = 0;
// newVolume = volume + 5;
msg.payload = volume;
if (isNaN(Dir)) {
global.set("LoungeDir", 1);
Dir = global.get("LoungeDir");
}
if (volume <= 6 ) { if (Dir == -1) {
newVolume = volume + 5;
msg.payload = newVolume;
global.set("LoungeDir", 1);
return [msg,newMsg];
}}
if (volume <= 90 ) { if (Dir == 1) {
newVolume = volume + 5;
msg.payload = newVolume;
// global.set("LoungeDir", 1);
return [msg,newMsg];
}}
if (volume >= 90 ) { if (Dir == 1) {
newVolume = volume - 5;
msg.payload = newVolume;
global.set("LoungeDir", -1);
return [msg,newMsg];
}}
if (volume <= 90 ) { if (Dir == -1) {
newVolume = volume - 5;
msg.payload = newVolume;
// global.set("LoungeDir", 1);
return [msg,newMsg];
}}
return [msg,newMsg];
Here is the entire collection of Nodes

The amusing thing (or at least to my mind) is that if I hold the button in the Long_Press state, the volume (or brightness) will happily glide between 5 & 95.
Not a feature I can see using very often, but a nice side effect.
I hope this helps someone.
Best wishes,

Hi
I’ve managed to code my first bit of Javascript in a Function node.
It’s not pretty, but it’s working 
If you have a Velbus setup, you might be interested to take a look
Now here’s something really interesting…
There is a “Blocky” Node set for Node-Red
I wish I have known that before I embarked on my painful JavaScript journey
Oh well, timing is everything
Thanks for the tip @QuagmireMan
Hi All .From a Still LOCKED DOWN South Africa.
i have a question. not sure if this is the right place to ask. i use node red for my Alarm monitoring. but i have a slight problem i cant wrap my head around.
- when i havesay a Burglary condition. and the alarm goues in to reset time. (still armed away) my rule sets the alarm status back to disarmed. but it is still armed. how do i have node red look if my alarms armed input on my raspberry pi is still armed and send the armed msg. instead of the disarmed.
here is my flows.

Hi
Are you using openHAB2 to monitor the state of the Raspberry Pi input?
There’s a great openHAB2 “GET” node that queries the state of an Item when it’s triggered.
And the output is seen as msg.payload.state
And in you still want the state of whatever triggered the GET node, you can find it with
msg.payload_in
Does that help?
no i have OpenHAB running on a server. and node red sends the information to mqtt where openhab gets the information.
so basically the pi is just a unit running node red and node red gets the statuses of the gpio and send strings to mqtt where openhab subscribes to it. then the rule below sends a broadcast to notify me .
rule "alarm notify"
when
Item Alarm_Status changed
then
// do something
sendBroadcastNotification("Alarm " + Alarm_Status.state.toString + " - " + now.toString("MM/dd HH:mm "))
end
So I’m using Node-Red a bit to respond to value requests of OH items…and it’s working fairly well.
I saw this YAML script someone is using with HA
alias: Garbage Week
sequence:
- data: {}
service: alexa_media.update_last_called
- delay: 00:00:01
- service: notify.alexa_media
data_template:
target:
- '{{ states.sensor.last_alexa.state }}'
data:
type: tts
message: This week's collection is {{ states('sensor.garbage_collection') }},
and it needs to be put out {{ states('sensor.garbage_collection_day') }}.
HA has a system node, that allows you to script back to Alexa with the mixture of text and values…how can I accomplish this with OH??
EDIT - I ended up getting this to work using the node-red-contrib-alexa-remote2 nodes.
