Smart sockets and light switch recommendations

Hi, I’m starting to build my openhab system and currently have Philips Hue bulbs and wemo plug in smart sockets. I have replaced several light fittings in my house and they now use a range of bulbs so would like to replace the hue with smart light switches for each room, can anyone recommend any? I have been using the wemo plug in smart switches but would like to move to the smart face plates as the are look neat, can anyone recommend some UK smart face plates? Thanks
