Before purchasing this light bulb, I did some research and was told by Amazon customer service that the Echo Plus, could control them since it has a has a built-in Zigbee hub. I installed the bulbs and now I can control them with any Alexa device. However, when the power goes out and come on again the light bulbs automatically turn on, which is not acceptable. I contacted Amazon support and had been waiting for an answer since for their first recommendation to work I must purchase an additional bridge from Phillips for about $50. With the built in Zigbee hub in the Echo Plus no all the features from Phillips are available. Amazon even has a promotion when they sell an Echo Plus device with a Phillips Hue light bulb which doesn’t make sense if the full features are not available. This is misleading.
