incorrect ignition

when ordering light bulbs, it is not clear enough that they are different voltages 110v~ or 220v~ so I burned all 4 I bought, otherwise I repaired them and now they work. When selling, pay more attention to the importance of the difference between models.

incorrect ignition

with the lamp off, if there is a power failure when the voltage returns the lamp switches on erroneously: unusable! the firmware is update.

Unable to set schedules and timers for BL05-BL

Unable to set on/off schedules or set timers for my BL05-BL lamp using eWelink, . It also indicates that it is off-line when it it is not. Able to do simple turn on/off on demand, and the "rhythm live" thing.
