Disconnecting from cloud all the time
It’s the worst smart system I’ve ever had, the app doesn’t connect with the bulbs, the devices are being shown as offline after not using them for a few hours and it’s extremely hard to establish the system. Not sure if it’s a problem of the app, the bulbs or the whole system but all together is simply crap and I don’t recommend it at all unless you don’t mind adding the device each time you want to switch on the lights.
