Daylight Savings Time is supported through the weather lookup and makes sense that it is also incorrect. The weather query also retrieves the day’s sunrise and sunset which explains why those are also incorrect.
We had one user on the forums who had an issue with the controller not reading weather reply when a firewall was installed between the device and the Internet. I think we might have found the firmware issue related to this and resolved in 2.1.4 which should be released very soon.
Is there anyway to disable the firewall just to test?
