TLDR: use UL, CSA or ETL listed North American gear that is labeled for a range of voltages inclusive of yours.
For instance North America uses 277V a lot for lighting, so many smart switches are UL-listed for 120-277V.
Argentina uses North American junction box sizes.
That box is exactly the form factor of the common US/Canada/Mexico junction box. (120V countries).
I am told Australia/New Zealand use the same box size (230V countries).
So, I think probably anything for the AuNZ market should fit your boxes and work.
And definitely anything made for the USA/Canada market will fit your boxes... the 230V question is, "Will it work on 230V???" For that, you'll have to go item by item. Many items will. See third section.
DON'T buy cheap Cheese junk!!!!
Amazon and Alibaba sell equipment that is dangerous. It isn't guarded to avoid shocking or starting a fire. It's made of the wrong plastic so arcing inside it will catch it on fire, and it will emit toxic smoke as it burns. It'll kill you in your sleep. They do these things because it's cheaper.
Any marks of "CE", "CCC", "FCC" or "RoHS" are fake, and do not reflect quality. CE only has force inside the European Union, so it means nothing unless you physically drive to the EU (i.e. French Guinea) and buy it inside a reputable bricks-and-mortar store.
Google "NRTL" for a list of reliable marks which can be counted on: generally; UL, CSA and ETL.
Searching for competent, listed US/CA-market smart devices capable of operating on 230V seems to be the smart play here.
Many genuine NRTL-approved products work on 220V
Because 220V is a North American voltage (well, 240V, but no real difference). And we also use 277V for lighting.
And it's better than ThreePhaseEel says. I randomly checked consumer tier products, and mind you, these are the very first two I randomly checked, I did not cherry pick, so I didn't check 15 to find 2, I checked 2 and found 2.
So yeah. Insteon or Leviton will work fine for you at the least, and I am sure you will find many more if you look.
