Re: OK.. Weird one here - a shredder

["AZ Woody" <Reply@xxxxxxxxxxxxxx>]

I do think it was a "brown out" type problem...

I moved the shredder to an outlet across the room (the outlet was on the
same wall all the smarthome 2-way wall switch) and the problem is gone.

I tried a filter and it didn't do anything (had a spare one)
