I have both of the bulbs under a wifi network from M9plus deco system.

If there is a power outage, when the power returns, both of the bulbs turn on even if before they were turned off. 

The L510E needs aprox 10 min. to reconnect with the internet so I can control it from the application but L530E never connects again and stays on until I reset it and install it again through the application. Up to date I did all of the updates available.

The thing is that I travel a lot so what happens if I'm away for days and everything turns on in the house and I have no way to shut it off? Except the obvious solution to unplug the bulbs before going away is there something else that I can do? Am I missing some adjustment?

Thanks in advance...
