Hello,
When I turn on kettle and microwave oven in my kitchen, the microwave oven creates current splash (for about 50 milliseconds) at start and then power goes down to normal consumption approx 1000W. The kettle is clear active load with power 2000W. So the summary power is 3000W, which doesn't exceed 4 Pro power limit.
I have one suggestion to fight with power splashes when some device starts to work. If it was possible to enter the time (for example 500 msec is enough) in device channel settings, how long the the overcurrent occurs, and if overcurrent lasts more than the value set in device channel options, then switch the channel off with status "OVERCURRENT". Maybe it's possible to implement it in the next firmware release?
Sorry, if the problem is already solved, bit in that case I would be thankfull, if point me to solution.
