In terms of IoT devices, now I've found a new candidate for world's stupidest idea for connecting things to the Internet.
Meet a candle that you can start up, with a real flame, from your smartphone app.
The mind just absolutely boggles ...
Yea, but can it alert me if I leave a geo-fenced area while it is lit and prompt to self-extinguish so I don't need to turn the car around? That, I might be interested in. Answer: No, you put the cap back on to extinguish the flame.
Or, you could go LED. Much cheaper and no refills.
