Need help converting dumb switches; one w/o any lights, one w/ Hue bulbs (self.homeassistant)

I'm looking for a smart home solution use two switches in my living room (EU), in order to make them just smart enough so I can control some devices. The setup isn't very complex in itself, and I'm pretty sure it's doable - I'm just unsure what I'd need in order to use these switches in a 'smart' capacity...

This is what I had in mind:

  • On-off switch, connected to a single light with three Hue filament bulbs. I'd like this one to always be powered, as to make them always controllable
  • On-off switch, which should be connected to a light which isn't in use at all. Once this one is 'smart', I could control all other smart devices in the living room like a 'turn off everything'-button.

I have a Hue bridge and a Home Assistant instance running in my home.

With regards to wife-approval-factor, I'd rather leave the original switches in place, but I'm open to suggestions. I hope one of you can steer me in the right direction.

Edit: if this isn't the right community for the question, I'd understand, but I wasn't sure where to put it otherwise... I'd be open to suggestions to that too.

There's nothing for a ground pin to be connected to, the case is plastic.

The bigger issue is that a lot of light switches also lack a neutral connection. They have live, and switched live. You can get devices to allow them to scavenge power, but they can also cause led bulbs to glow dimly.
