My Aqara smart plug says it can handle 2300 W, which should be okay for the kind of dryers sold in Europe (apparently the new ones are mostly sub 1000 W).

In the US electric dryers run on 240v which has a different plug. Not sure how they are in the EU but it's something to consider when looking for one of those plug monitors

That’s easy, the whole Europe is 230 V at 50 Hz and basically the same plug (except I think Switzerland and the UK).

I'm in AU, certified smart plugs are 240V/10A. Dryers don't need a special outlet.
