Once upon a time, in a company far, far away, they build a bike shed. The actual bike shed. Surprisingly without any bike-shedding. But then they were wondering how to give access to all the cyclists to the yard bike shed was build on. It was not a highly secured area, but still, it was behind gates so no stray dogs or stray cars could enter. They already had a remote-controlled gate via special key fob. But those were expensive, required some tracking, it took quite some time to order a new one and in general there was quite some overhead managing them.
IoT or Internet of Things is a real hype nowadays. Everybody is talking about it and everybody is doing it. Especially companies producing various electronic devices like light bulbs, electric switches, thermometers, scales, CCTV and such. Everything can be smart – even your toilet. All you need to do is to measure something or replace the manual switch with electronic one and connect it to Bluetooth, Zigbee, ZWave or even WiFi and you have a smart device that people will pay a hefty price for. But there are some issues (apart from the obvious one that not all those devices make sense).
