Thanks to my external antenna, almost all of my devices are connected direct to my HE. And most of the time, the response from my devices is sub 1 second. However, about 10% of the time, my battery operated (motion, switch) devices will take about 5 seconds to respond. This usually happens when the HE should otherwise not be doing anything (day, evening).
Why do my battery operated devices sometimes take much longer to act???
Is it just the specific device make/model of device?
Is it because HE tries to optimize/repair/test the Z-Wave mesh every night, and this changes the previous fast routing of these devices?
Is it because the HE is actually busy mining Bit Coins in the background and doesn't want to be disturbed?
