I am not sure what you are after, a two way switch allows one to switch either one light or another light, however the same switch as a pair can also allow one light to be controlled by two switches, we can add more switches called intermediate to have more than two switches, but this is not three way switching, it is still two way.
But you could have a three way switch lighting three lights, busy, vacant, knock for example, I assume you want multi-switches for one set of lights?
I used Energenie MiHome, not impressed, they can be hard wired, use a remote, or phone, or PC. But Lidi have been doing Zegbee smart switches which do seem to work out cheaper. I got a three lamp unit with GU10 lamps and a remote control. The remote will work with any of their smart bulbs, so it works a wall light and a bedside lamp in my wife's bedroom, and the GU10 lamps it came with just use the phone to control them.
The lidi remote has a plate that can be screwed to wall, and it is magnetic so the switch then sits in the plate like a light switch, but can also be removed to use as a remote. It has worked well for me.
The Energenie MiHome however also worked well when first installed around 4 years ago, HomeBase were selling them off very cheap so I got a load more
and to start with seemed to work well, however Nest removed support so the TRV heads no longer connect to Nest Gen 3 thermostat, and of the 5 light switches only 2 still working, and also a socket has gone faulty, this has taken 4 years, but when the lights decide to flash on/off/on/off you have to turn off power to return to normal switch, and find a normal switch, which was a real pain.
So now using plug in adaptors, at least if it goes wrong easy to unplug. So gone off Smart light switches and sockets built in, now use type I can unplug if it goes wrong.
