I swapped out my trendnet 5 port 10g switch for a 2nd 8 port managed that i got on a good deal used.
it is rack mount and the older was not..
anyway after doing it and getting into the rack and getting it on the same power as the other switches so i can easily reboot all switches with a kasa swith and got it working stuff was down for awhile.
when it came back up i got a notification that the hubitat had rebooted.. i couldnt figure out why as its downstairs and the net rack is upstairs...
traced it down to this rule which i had totally forgotten about.. duh..
