All of that said, I haven’t heard of any houses in the United States built after 1950 that didn’t have a neutral wire at the outlets. That would be really unusual unless you had knot and tube wiring, and that usually means a house built in the 1920s.
Are you sure you don’t have Neutrals at the outlets? Or are you not in the US?
If you’re not in the US, the device selection is going to be different.
