RGBW2 sunrise/sunset scenes

  • I see that the RGBW2 inbuilt website allows the device to be turned on/off by time or sunrise/sunset, but as I have a number of these devices, I would prefer to set a scene via the iOS app and control multiple devices together.

    However the iOS app only appears to allow time and not sunrise/sunset. Am I missing something, or is this a limitation of the iOS app?

    Is there another way to activate a group of RGBW2 devices at sunrise/sunset?
