It depends on the Wi-Fi router that you have at home. You can try to reset the router and install the new settings for the connection.
Also, you can try to connect to the smart bulb directly. I use this way of connection to establish the connections to my
Vont light bulb. It is very cool to switch the color of the light just lying in bed. You can create a special atmosphere in a room that fits your mood or goals. You can turn a mild and soft light on and create an atmosphere of calmness in a room.
Another thing that I like is that these bulbs help me fall asleep because I turn them on the right before going to bed, and they set my mind in order.
