Yes, let me just rush out and get spark to rewire my home for £4000 adding a whole new set of 4 plug rings and dozen new plug sockets tracked into the walls.
I checked for fires, there are some, but either because people are dumb enough to run 16 Amp heater off a 10 Amp plug or because they did dodgy hacks to them, like this guy:
https://community.home-assistant.io/t/warning-burned-sonoff-basic-modified-hacked/84775Emmm... running wall heaters on them and hacking an inappropriate diode into the main line. It's also an older model with non reinforced tracks. Darwin award in my view. You just can't fix stupid.
Mine are rated to 10A and I do not intend to run anything close to half of that on them. I'm in the UK so all my plugs are fused so if the device connected to the switch shorts the plug fuse will blow, there will of course also be a fuse in the 4 way power bar or it's plug. I can go as far as replacing the fuse in the plug with a 5A fuse. The switch itself has a fuse for it's own power supply and it looked to be up to standard when I took it apart.
I have done a bit of due diligence and it does look like the CE marking on the device is valid and the company is prepared to send the test reports and certificates to you on request. This would mean that as long as they are not modified my house insurance would still be valid.
