I'm using four different kind of device: Samsung S7Edge, Samsung S3 Tablet, P9 Huawei and an old Samsung tablet.
On all of above devices the problem is the same.
The network, during the reported problem, was fine and no, there is no solution. I have only to turn off the light and then on again. But I can do it only when I am at home...
Last question: I've just ordered another 3 bulbs. I'd like to use theme outside, into a water proof lamp holder, do you think could be a problem? (I mean: cold, umidity and so on)
