Positive; Intelligent LOHAS lamps do not require a hub. Lightbulbs often lose their WiFi signal and need to be reset. (2) out of (5) newly received lightbulbs will not connect to the router. After replacing the new blocks, the working ones (2) were defective. Newer GU24 bulbs are not available anywhere, I had to buy a GU24 adapter for a screw.
