Sunrise alarm and HA voise assistant

Hi There

I’d like to make my own sunrise alarm using the IKEA tarnaby lamp. that can be controled by home assistant and also be a home assistant voice assistant as well.

It uses an E14 bulb and has a physical twist knob that controls power and dimming.

There’s a decent amount of space in the base which could fit a Pi zero etc.

Does anyone have any idea what hardware I should buy to do this and what software avenues I should go down?
I’ve used diet pi on a zero to create a VPN tunnel before but nothing else.
