I found that my newly added Aeotec SmartSwitch 7 switched off and then immediately on again for at least 2 times within 5 days now. The permanent load it has to take is about 130W.
No power event was detected, it was just like an off/on command was sent.
I have 3 more of these devices and know how they behave on an overload.
Aeotec support asked me for logfiles, my question is, will the Heart stand a permanently active Z-Wave debugging mode?!
The error is not reproducable at all, so the only way seems to be activating debug mode, hoping my browser can handle all that Z-Wave chatter.
