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.

You don't need to ground your Shelly if the circuit is otherwise properly grounded. The Shelly will fail open if something internal shorts.

Per the rest of the discussion re: hot wire loops to switches with no neutral or ground, just put the Shelly into the upstream junction box. (Wherever the switch wire branches from the circuit. Usually that's where the light is.)
