   I've a similar thread in c.o.l.misc in particular. Although that's   
   headed 'smart plugs?' and looking for a wireless solution.   
      
   My own feeling is that the bigger the gap between mains and my   
   electronics, the better, and wireless is a good way for this.   
      
   I suspect off-the-shelf products, at least consumer-grade, will be   
   wireless. Might there be mileage in running network wires to local   
   wireless repeaters, then using wireless switches? Or use a   
   network-over-mains scheme?   
      
   Oh, and if you only need a PI for local control, with no networking,   
   don't forget the PI can be an AP and run a nearby wireless device   
   without a central router.   
      
   (FWIW I'm leaning towards the Shelly Plus Plug, at around £20. IIRC   
   there's a euro version too. It's the only one I've found that seems not   
   to need cloud servers.)
