Writing time to knx address

Bor Buh 4 months ago in Devices / KNX updated by Ricardo Pinto | visiontech pt 4 months ago 2

Hi all 

I have a time node that works and displays time in the visualisation correctly. Problem shows up when i want to send time variable to KNX address and show it on the switches, it always stays at 00:00.

Addreses are the same 0/0/1  and 0/0/3 on switches.

Upon further investigation the problem was with date time variable send system time interval being set to 0 the controller was sending address as unix time of 0.

After changing it to 1 it works, but for some reason it sends it twice

Hello,

That happens because you have "Send Value Cyclically" set to True, plus the "Send System Time" also as True. both with the same time. That's why you get the value twice.


I'd advise for you to just use the "Send System Time", and set it to a comfortable time, you don't need the time to be sent every minute. And disable the Send Value Cyclically.


In my case and experience, I set the time to be send every 1440 minutes, which is 24h. This is just to assure, that in case of a power outage, after 24h max the time will sync to the touch screens.


Best regards
