After updating to core-2021.4.6 they are changed around so that the one with the _2 is now downstairs and the other one is upstairs. This screws up all my automations, buttons etc.
I have seen this problem a while back (i had other problems and reinstalled) but i never found a reason for the problem.
Further i have seen similar behavior with a number of cameras that keept changeing around after every other reboot. So im not sure what causes this type of problem.
I see other topics where and “_2” or “_2_3” shows up after an entity ID after restart - this is not my probelm - mine just get swapped.
questions one:
how to fix
qutstion two:
how to prevent
(running latest versions of supervisor and core on a rpi4)
