Smart Light-Switches & Plugs

Hello,
I am trying to decide on what light-switches and smart plugs to buy from my HA fresh implementation:

My CTQs at high level will be:

  1. Easy integration with HA
  2. No need for grounding-cable (I do have Phase & Null in my home)
  3. No noise in the switch when “smart-using” them … here I am not sure if this is a ‘thing’ or is my imagination only :slight_smile:
  4. “EU compatible”
  5. Dimming … if possible

Do you have any good experience and can recommend me … both switches & plugs ?

PS:
I am looking at this as I understod now there is a component that auto-integrates them with HA and you dont need a custom firmare anymore.
