Well it depends how techy you want to go.
I’ve been using a number of Energenie light switches, wall sockets and plug adaptors in two houses for a few years and have found them to be good.
Although you can get a hub and a remote (they work with Alexa also) I mainly control mine using a Raspberry Pi which switches lights on and off according to the sunset/sunrise so they’re completely automated.
I can also switch them on and off using my phone just by running a simple Python script.
I’ve also installed Fauxmo on the Pi so it looks like a Belkin Wemo router to an Alexa device – so I can also just tell Alexa to switch [whichever] lights on and off.
It’s a really adaptable system and the rangle is very good. The wall light switches, obviously, do a number of downlights and outside lights while the wall sockets/adaptors can switch groups of table lamps. In our holiday house, which is totally electrically heated, there’s a Pi that checks the air temp every minute, records it to a cloud service and switches the heating on and off using the wall sockets.
As I said though, you don’t need a Pi… just use Alexa and/or the remote.
Forgot to say…. no neutral needed for the light switches.
