I am experiencing a strange issue with the date and time settings of Comfort:
I use Windows 7 in an Oracle Virtualbox environment with Comfigurator 188.8.131.52
In Configuration - Modules and Settings "UTC+1 Vienna" is set as timezone, and the daylight saving (Schedule - ) is set to be active until end of October. UCM-KNX is set to send date and time from Comfort to KNX.
Comfort was programmed yesterday evening to display the correct date and time using the Transfer - Set Date & Time option
Sometimes during the night an hour was lost, at 06:15 a.m. the Keypad only displayed 05:15 a.m.
It is now 09:20 a.m. - I started Comfigurator, and the answer to DT? is:
Reading the Keypad confirms that also the date is wrong. I am not sure whether this changed simultaneously with the time. But there is more:
Transfer - PC-->Comfort (with the Option Set Date & Time selected)
...a very good point, thanks! I just saw there is a new NTP sync feature in ETH03, which is configured via the Comfort Server Manager - but my ETH03 is not detected there. I will go on fiddling around with that.
Thank you both for your help, it works now! The following was necessary:
Connecting the PC directly to the LAN subnet where Comfort is (so the Server Manager would find the ETH03 interface via 184.108.40.206 multicast packets)
In the Virtualbox network setup I had to use "Bridge "instead of "NAT" mode (same reason)
Upgrade of the ETH03 firmware from 2.09 to 2.12 (resolved the issue with the changing date)
Setup of the SNTP function of ETH03: GMT+2 is correct (although I live in a UTC+1 timezone, but we have daylight saving)
The issue was a bit tricky to solve because the Server Manager is quite hidden, the ETH03 interface was not shown (and therefore not configured), and despite lacking configuration the SNTP function of ETH03 was active by default. Additionally, this was overlayed by the 2.09 firmware bug crippling the date.
