Don't seem to be many others, there's this abomination which clips over
the existing switch and manipulates the rocker(s) with motors and cams

So you are unlikely to find one.
A rewire is required to achieve what you want.

Historically this was circumvented by drawing a very small current

through the lamp to power the switch. The difficulty with that approach
was that it only works well with filament lamps, and may either simply
not work, or more likely, cause problems with flashing or dimly lit low
energy lamps these days.

but that requires access to a neutral.
Another approach to consider would be a remote control lamp with home
automation - so you can leave the switch on, and then automate the lamp
instead.

For example

any of those three can use an adapter -
https://www.tlc-direct.co.uk/tcl/search?query=ZV210&footer_search=submit
to allow them to operate without a neutral at the switch. (Looks like
an expensive capacitor!).
The Timeguard ZV700B will also work with >11W low energy lighting.

with a 100R resistor in series.
You would probably get away with using a normal mains input suppressor,
like:
http://cpc.farnell.com/ampohm-wound-products/fe-sp-b-hdr28-470-100/contact-suppressor-0-47uf-100r/dp/FT00726
(which if it works, would be slightly cheaper to run as well!)

I'm surprised anyone could be bothered with that last idea.
Surely for a more random way, a simple bi metal strip type is best, unless
you want precise timing of course.
