Cordless light switches

I've got an upstairs hall light with a shared neutral issue, so after my recent consumer unit replacement, the downstairs (half of an original two-way installation) switch has been disconnected.What I need (I think, I really don't want to start chasing the walls for new physical wiring) is a light fitting that responds to a pair of cordless switches, one to be glued on the wall downstairs, the other upstairs. So that pressing either of them turns the light on/off.Despite reservations about cordless gadgets in general, I don't mind if the switches have batteries in them, requiring periodic changing.SWMBO has also found a ceiling light with a "night-light" feature, so that even if switched off, it glows a little after dark. Hopefully that won't complicate things. [At the moment we have a night-light plugged into a 13A socket in the upstairs hall, to help prevent us accidentally falling down the stairs in the dark]

and if you have 2, it will be the one that covers the bit of the house you are that trips.

The importance of which rather depends on what else shares the RCD. Earth leakage trips on lighting circuits are fairly unlikely.

Or if the install has a "whole house" RCD then it also (while far from ideal) makes it no worse.

True, and even there you can have a branch at the CU (although that might confuse someone seeing two cables and expecting a ring!)
