Need guidance on adding 1-gang light switches

I currently have some smart plugs (Tuya) but want to start adding light switches, replacing them as needed. I’m completely overwhelmed with the types and amounts of options, and trying to see what is CURRENTLY compatible (I almost bought a Kasa light until I noticed the warning about closing off the local 9999 port) with HA.

  1. Would wifi or z-wave be better for my case? MQTT? I don’t want anything else operating in the 2.4ghz range.
  2. What can you recommend that is one of these, fits in a 1-gang box, and has good integration?

These would be for single pole only. Thanks!

Shelly 1 or Shelly 1 Plus.

Thanks, but I need actual switches.

From what I gather, these Shelly switches replace a physical switch with a relay behind a panel?

Yes they do.

If you need actual switches, you will need to be more specific. EU or US form factor ?

1-gang, US.

Ideally looking for ones that play well with HA, and don’t require a custom firmware or jumping through a lot of hoops. Thanks again.
