KNX node for node-red

[alexbeer]

Hi TheMax74,

you KNX-ultimate Node is just awesome.
I am currently working on receiving several Data from openweathermap to My KNX.
I am struggling with the Sunset datapoint.
OWM offers the Sunset as

[LIST][*]sys.sunset Sunset time, unix, UTC[/LIST]

, See https://openweathermap.org/current

I would like to have the local sunset Time at KNX.
I used your example [/URL]https://github.com/Supergiovane/node...ateTime-to-BUS
https://openweathermap.org/current" to send the unixtime to KNX via DPT 10.001- unfortunatly not in local time.

What way do you recommend to convert UTC unixtime to local timezone and send that via your node to KNX?
can I use the js DateObject Functions (
https://developer.mozilla.org/de/doc...caleDateString)

kind regards
Alex

Hello Alex
Thank you for using my node.
try this in a function Node. Please replace "Rome" with your current city of reference and “new Date” with wheater service’s datevalue.

For DATE:
return {payload:new Date().toLocaleDateString('it-IT',
{year:"2-digit",
month:"2-digit",
day:"2-digit",
timeZone: 'Europe/Rome'})}

For TIME:
return {payload:new Date().toLocaleTimeString('it-IT',
{hour: '2-digit', hour12: false,
minute: '2-digit',
second: '2-digit',
timeZone: 'Europe/Rome'})}

But the xrk solution may work better.

Thanks for quick Response.
Have Not tried IT yet. Will it be still possible to send a Date-String to KNX DPT 10.001 instead of a Unixtime?

[TheMax74]

Knx-ultimate accepts string as datetime, so yes.

Hi,

I tried the following:

var unix_timestamp = {payload: msg.payload.sunset}; // i.e.: unix_timestamp = 1578238021

dateObj = new Date(unix_timestamp * 1000); // timestamp in  ms

return {payload: dateObj.toLocaleTimeString('de-DE',
{hour: '2-digit', hour12: false,
minute: '2-digit',
second: '2-digit',
timeZone: 'Europe/Berlin'})}

As a result I do receive: "Invalid Date" - something seems to be wrong with the declaration of dateObj.
What do I miss?

Hello Alex
unable to try now with my pc, but try to replace

var unix_timestamp = {payload: msg.payload.sunset};

with

var unix_timestamp = msg.payload.sunset;

[alexbeer]

Thanks, that is the solution!

i have a question.

i have two function nodes on the Exit of the Hue with following Code:

Node1:
return {payload: msg.payload.on};

Node2:
return {payload: msg.payload.brightness};

Is it possible to have this in one function with two outputs. In the settings of the function node I can select how many outputs I need.

[TheMax74]

Hello
yes. Please see here.

I appreciate that!
As soon as I have further NR challenges, I will come back to you.

Sorry for OT:

Wie hast du das hinbekommen, dass die Bridge nach einem weiteren Deploy aktiv bleibt?

This is INCREDIBLY EASY with your node and the "node-red-homekit-bridged" node.

Bei mir funktioniert es immer so lange, bis ich irgendetwas ändere, danach geht über das iPhone gar nichts mehr..
Magst du mir vielleicht mal deinen Flow zeigen/schicken?

try RedMatic-HomeKit. I have the same problem and I mean there is a Issue on Github.

Awesome node. I use it to log all KNX traffic to influxDB
