In my case it was an unlisted not approved device being plugged in that was the cause of the "noise". When made the statement from the Siemens rep to the HO they acknowledged something they had just got was being plugged in, they discontinued use and no more tripping. Seems to confirm the issue was "noise". Cheap amazon and TEMU products that is not listed for use in the states that HO are buying is the issue. IMO.
Had some local guys bragging about getting some SD AFCI breakers off TEMU for only $25. Can't directly prove anything about the breakers, BUT, I suspect they are not what they appear to be. Heard from a UL rep a couple of years back that they caught several containers coming into a west coast port that had SD breakers that were no more than switches. These are ones they caught, how much other garbage is making its way in without discovery.
