Unfortunately, not all smart lights can. Some smart lights work with several platforms while others are limited. There are smart lights, which use Google Home, IFTTT, ZigBee, SmartThings, Apple Home Kit, and Stringify, among others. If you want smart lights compatible with Alexa, you need to choose the right one while shopping. If you rush to buy just any kind of smart light, you might not enjoy using some features to the fullest.
