Smart switch software for Linux/Ubuntu - is there anything available?

[Chris Green]

Are there any brands of smart switch (smart lights, smart sockets,
smart plugs, whatever) which offer simple Linux interfaces?  I don't
have a 'smart' phone because I don't get on with them but I do just
about always have my laptop with me.  Also a major use of a smart
switch for me wouild be operating/resetting devices on my boat in
France remotely and I would want to do that from my desktop machine at
home.
