KNX node for node-red

[TheMax74]

Hi Stives,
you need to get msg.payload from the KNX-Ultimate node, then do some manipulation on that payload and then send it to HA.
In the property window, i see your're using {{time}}. From where you take this variable?
Are you new on HA programming? This info will help us to help you.

[Stives]

Yes, I started a month ago with HA but I have already integrated all my KNX equipment

With the KNXULTIMATE node I can retrieve a number from KNX to HA and I did something similar for Date and Time but the KNX format does not seem to be accepted by HA.
The {{time}} comes from the node I imported with the link given previously.

Sorry for this question, I am just starting to use node-red (via iobroker): How do I update knx-ultimate? I am still on .8

In Node-Red, click on top-right corner the three bars (so called "hamburger" symbol) and then Palette verwalten.

Hi Matthias,
please take your time to read the WIKI and SAMPLES as well, because there are many new things.

This is what you're looking for.
Unfortunately, i don't use HA nodes, so i cannot help you anymore, but someone can help you. You need to write a function that parses this payload and send it to your HA node.

Very difficult for me to do a function because I don't even know the format expected by HA !

I also have a problem with updating knxultimate on HA.
I upgraded from HA / Node-red / manage palette / knxultimate / update and now I have the following message that displays "Node-RED must be restarted to enable upgraded modules".
I restarted HA (so Node-red) but the message persists ...

[TheMax74]

HA and Node-Red are two separate apps.
Restart the whole PC.

Thank you. It's up to date!
The most difficult remains to be done !

[TheMax74]

Stives,
if you can tell me what the HA node does expect as input, i can write the function for you.

[Stives]

It is very nice! I am trying to test this code which according to its author works.

I checked the knot. When I click on timestamp, the date and day are displayed in the Entity Lovelace card.

With this node connected to the KnxUltimate device node, on each write to the GA, only the time is transmitted to the HA entity. The date displayed is today's date.

Hi Stives
Please use the code tags (the #) to paste here the code, otherwise the forum's editor will format the script and we cannot paste it into node-red.

[Stives]

Yes I am sorry

and then Palette verwalten.

Thanks for your help!


Unfortunately, there is no update button for this node!? Screenshot 2021-04-14 10.16.20.png

Hi Stives
the function node contains

var d = new Date();
msg.time = d.getFullYear() + "-" + ('0' + (d.getMonth()+1)).slice(-2) + "-" + d.getDate() + " " + ('0' + (d.getHours())).slice(-2) + ":" + ('0' + (d.getMinutes())).slice(-2) + ":" + ('0' + (d.getSeconds())).slice(-2);
return msg;

You will obtain the current date everytime, because you get the value from the javascript object "Date".
Replace this:

var d = new Date();

with this:

var d = new Date(msg.payload);

Now, as soon as your 2/6/40 receives a datetime, the function get their msg.payload and transform it in a date.
