This isn’t a Blynk related issue, but I’ve seen a number of people on this forum talking projects made using Blynk and 433MHz transmitters to control mains plug-in switches.
This recall notice for EverFlourish remote sockets just popped-up in my inbox and I thought I should share it…

Apparently these remote controlled sockets sold by B&Q in the UK are being recalled due to a potential fire risk.
I’m guessing that these sockets are churned-out by their thousands in China and re-badged under a number of different brand names, and probably sold with mains fittings for Europe and other countries as well - maybe with the same dodgy internal circuitry. If you have 433MHz sockets that look something like these then you might want to think about replacing them.
