I bought this lamp here: Avatto
This is the box that the light bulb comes in.
Instruction in the English language.
A little specification:
light Bulb: RGB + warm white + white (2800K-6500K);
Lumen: 100 LM / W;
Applications: Smart Life and Tyua.
I connected the light bulb to the Tyua app. Connected without problems to my wifi router. The light bulb works smartly, I don't see any delays through the app. Also, Yandex station with Alice saw the light bulb without any problems.
A little video about the different modes of the lamp.
