I brought Havells smart bulbs both one with multiple colours and those with warm and cold light.
Not a single one has worked except for a few measly hours.
Wipro smart are not great but these are just a waste. They died on me within a week.
The best part is they sometimes just light up on their own as I have not unscrewed these yet from the holder.
Havells manufactures subpar and substandard product.
And yes the app is equally bad and unintutive
