When connecting locally to the OBi's integral web server configuration pages, the configuration of the OBi Daylight Savings attributes are available in the System Management - Network Settings menu.
The DST setting is available in OBiTALK on the main Device Configuration page. The Network Settings are not available on the OBi Expert Configuration pages. The changeover day / time is set by the OBiTALK service. If you have a specific time-zone where you wish to deploy the units, you can discover this time on your own by setting the DST via OBiTALK and then inspecting the device web-page setting. Alternatively, you can e-mail
support@obihai.com with the specific time zone and request to know the OBiTALK setting.
FYI only, from the OBi Device Admin Guide:
