Spacelynk, change clock with script

[P_Bergman]

Hi,

If the spacelynk aren't connected to a network/NTP. 
Is there a way to change the clock, due to daylight saving time?
Through a scheduled script perhaps?
Anyone with a code?

Or is there something "built in" for this that i have missed?

Regards

 Set you time zone in Configurator -> Utilities -> Date and time

This can be done from script:

--FROM KNX TO CONTROLLER

date = grp.getvalue('1/1/1')
time = grp.getvalue('1/1/2')

cmd = string.format("date -s '%d-%d-%d %d:%d:%d'", date.year, date.month, date.day, time.hour, time.minute, time.second)
os.execute(cmd)

It might be needed to disable this setting:

Add a DCF77 receiver / time giver to your KNX objects and you don't need NTP, but as with any modern IoT product i don't understand why it's not able (or better said allowed) to connect to WAN to get the NTP...

Hello P_Bergman!

Is this topic solved?! Please let us know 😉

👍 ok, great, so if you choose an area/city that uses daylight saving time (or not), then clock will change accordingly?

Yes, the controller will run his clock according the regional settings you have set including DST,

However when you send a new time/date via script the controller takes that over without calculation for it’s current regional settings so the time you send must be the current time for the region you are in.

When having a DCF77 or KNX time sender to set the date and time via script you must set the correct region and DST there as well.  

My advice is to connect the controller where possible to the great IoT world (it’s made for that 😉) to benefit of NTP and more..
