After working fine for weeks, my on/off routines based upon sunset/sunrise stopped working yesterday. Location is Fort Collins, CO. One Hue ambiance bulb in the living room and three Hue white bulbs out front are involved. Am running the latest software/firmware for the bridge and all bulbs. Manually turning the bulbs on/off via the Hue app or Apple HomeKit works fine. Is this happening to anyone else? Suggestions?
