Z-Wave Zigbee 433mhz Hardware Requirements (UK)

Hello

I’m extremely new to the home automation scene and am looking to expand the few lamps & sensors I currently have. If possible I would like to make a cross compatible hub using a spare raspberry pi.

What would be the best hardware to support the following protocols, Z-Wave Zigbee 433mhz?

I’ve tried to search around but I am so confused on what is compatible and what hardware would be best to use.

Any help would be appreciated

Many Thanks
Mark
