Electrical Wiring in the Home/Switch to plug


Older home with aluminum wiring. We have changed out all our plugs and switches in this home, everything is working fine.  However I just went through all the plugs to double check and seem to be getting error messages in the plugs that run from the switches and turn on lamps.  i believe I connected correctly but can I double check with you?  So aluminum switch/plug to start with...  Tried to just connect as usual, with blacks going on right side, white going on left side and ground.  Doing it this way doesn't work , so i snap the right side , and it works the switch to the plug.  However I am getting and Open hot message on top plug and bottom is testing okay.  Is this correct?  Would this pass inspection?

Must have done something wrong

Side is irrelevant, hot to brass screw, neutral to chrome.
Are these new devices listed as copper/aluminum? You can't just install copper only devices to aluminum wire.

Don't understand why you "snapped" the device - I guess you mean you removed the bridge between the two screw terminals. Was the old device bridge removed?

How many cables are at switch? [Cable is sheathed group of conductors - black is a single conductor, white and black inside outer covering is a cable]

How many at receptacle?

Did you change any connections?
