The Internet of things (stylised Internet of Things or IoT) is the internetworking of physical devices, vehicles (also referred to as "connected devices" and "smart devices"), buildings and other items—embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data.

The Internet of things (stylised Internet of Things or IoT) is the internetworking of physical devices, vehicles (also referred to as "connected devices" and "smart devices"), buildings and other items—embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data. In 2013 the Global Standards Initiative on Internet of Things (IoT-GSI) defined the IoT as "the infrastructure of the information society." The IoT allows objects to be sensed and/or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit. When IoT is augmented with sensors and actuators, the technology becomes an instance of the more general class of cyber-physical systems, which also encompasses technologies such as smart grids, smart homes, intelligent transportation and smart cities. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. Experts estimate that the IoT will consist of almost 50 billion objects by 2020.

Automatically connect IoT devices to a VPN

So I have this GCP setup with IoT devices, but I want to SSH into devices that are geographically very far. Of course they are not on the same local network. My current idea is that I host a VPN and connect them through it while I am myself a client…

How to embed a tls certificate into an IOT device

We need to protect the authentication process to devices we produce. Since these devices are installed in the customer (typically a non professional) network, we can't get a regular tls certificate from a CA. Is there a way to get a trusted…

Duplicating IoT traffic

I have a simple IoT temp sensor (from China) and I can change the destination it routes traffic to. I want it to continue sending to their system AND to mine (redundancy, resilience etc). The sensor does not support sending to 2 destinations. I use…
