KNX node for node-red

[fbirkholz]

The fastest way is: do not convert. The modes are only 5.
What is precisely your actuator?

I'm using both AKH-0800.2 and discontinued AKH-0800.1 (which is not that detailed on specially the analyze values in handbook and actor sw)

Meanwhile I recognized in this forum that exactly HVAC value is interpreted different by vendors.
So you might be right for Gira but not for MDT and not able to solve it finally. If I find this article I'll link it later.

thx and don't hurry that much - as repeated it's not so urgent.

Hi Franc
first of all, untick (deselect) "react to read" as showed here:
Node-RED.png

Then: in the UI Label, you cannot set Value Format to{{msg.payload}}
msg.payload is an object containing many properties. You need to select which property you want to show.
If you want show the Heating/Cooling mode, you must write: {{msg.payload.HeatCoolMode}}
I think msg.payload.HeatCoolMode ist TRUE for heating and FALSE for cooling.
Then you'll need to adjust the label by showing, for example, "I'm heating" while true and "I'm cooling" while false.

Node-Red is a very powerful and addicting software. I suggest you to learn about it and you'll never regret using it.
I found myself to have moved ALL MY LOGIC to node-red, because it's simply sooooo powerful!

Hi All,

i hope you will be able to help me setting up a node listening to a reed contact, changing when a door/window is opened or closed.
Somehow i seem to not get this working.

My node looks like as follows:

reed1.pngreed2.png
The issue is that it won`t react to any changes made on the bus. It looks like it somehow it does not recognize when the actor sends "on" or "off" to the group adress.
I guess something in the configuration might be wrong and maybe my understanding of the node is not correct as well

Best regards

FRO Can you post a screenshot of ETS Group monitor showing that GA 5/0/0 is being communicated?

[FRO]

Sure: (just to mention there are 2 contacts per window to get all the states)

If you try in KNXultimate node under Gateway to directly connect to the IP of your KNXnet/IP-Gateway, does it work then?
If so, what switch you use and is it possible that it blocks multicast?
Is Node-Red running on the same PC where ETS is installed? If not, is the network configuration/subnet the same?

[FRO]

The KNXultimate node is defineltly working as i am using other nodes that are working fine. One universal that is just for testing and others to automatically turn on Powerplugs. ETS is and not running on the same computer as nodered, networks are not the same as well (different vlans), but there are no rules yet.

I am using the MDT IP Router as interface and the only way i got it to work was using multicast (its not even using the given KNX Adress):

It seems that you have two (or more) knx lines.
Did you "reprogram" (not only partial) the application of your linecoupler after setting the reeds/binary actor?

Sorry, I mixed up up GAs and PAs, so you've only one line...
But the MDT also works as kind of coupler between TP and IP, so re-program this one too.

The KNXultimate node is defineltly working as i am using other nodes that are working fine.

Does this mean that Node-Red is working for you, or that you also see other GA messages with KNXultimate node, but just not GA 5/0/0?
How does your KNX topology look like?

[FRO]

@PhilW Well i have two lines one indoors and one outdoors but the linecopplers are correct and the reeds/the actor is on the indoor line

xrk Both Nodered is working and i can see messages using the universal node for example... its not only 5/0/0, temperature from the weatherstation as "single node" works but if i open the door the corresponding node does not recognize the state this is why i think something in the config might be wrong.
My topology looks like:

1.0.x line indoor
1.1.x line outdoor

but i guess thats not the issue as some are working.

OK, but again, did you re-program the MDT Router after you changed the settings?

[FRO]

Aaaarg .... nevermind i have found the issue.....

My KNX IP Router has to be set to not filtering for both IP and TP line in order to get that working. I normaly would wan`t filtering to be enabled
I had filtering for the TP line and turned it off for the IP line. It seems that is has to be turned off for both....

PhilW yes i did that...

[PhilW]

Well, but even if the filtering would have been present or not present for both sides, the correct links should have been set if the download had been correct.
A download is always required
But lucky that it works now...

[FRO]

As i read the knxultimatenode is not yet working with filtering... but i might have missunderstood.

[xrk]

You need to include a dummy device in your ETS in the correct KNX topology line to emulate Node-Red for the filter tables to work and connect the GA (5/0/0) to this dummy.
No need to disable filtering in this case, but as already was said, after connecting the dummy to the GA in question, you need to reprogram the routers/line-couples in order to update the filter table in them. The filter table is automagically created by ETS for the routers/line-couplers, but it needs to be "downloaded" manually after each change.
