if you want local control, stay away from yeelight 1s. There is a bug that disables local communication after 8 hours of being powered
Excellent E27 smart bulb. It's pretty heavy, compared to other no-name bulbs. Which is, when you watch a review video from Smart Home Solver on YouTube, an indicator for good quality. He reviewed the Yeelight 1S and came to the conclusion that it's one of the best cheaper bulbs. Both white & colour brightness is good. Integration in my smart home with Yeelight APP & Amazon Alexa was pretty straight forward & easy. Just ordered two more of them because i'm really satisfied!
