This time I will share an application with great utility in our IoT projects. Dataplicity Dataplicity allows you to monitor, manage and repair your devices even when they move between cellular, satellite and fixed networks outside of your control. How does it work Dataplicity uses a secure HTTPS connection initiated by the client and opportunistically…
Virtualization is one of the most used methods to facilitate the compatibility of Software or simply the test of other Operating Systems, technically it is an operating system within another. I have tried for a long time Oracle VirtualBox is one of the most used virtualization software for x86 / amd64 architectures allowing virtualization. FreeBSD…

In this tutorial we will install OpenWrt a Linux based firmware / operating system, specifically created for personal routers. We will install OpenWrt on a Raspberry Pi 3 B + and turn it into a Wifi Ethernet bridge router. Mount OpenWrt on microSD card Win32 Disk Imager in case of being a Windows user….
I present the Dragino RS485-LN is an RS485 to LoRaWAN converter, a few months ago I ordered a couple of modules for testing. This converter would allow monitoring and controlling devices over long distances, adding the versatility of the RS485. Characteristics LoRaWAN Class A and Class C protocol (default Class C) Frequency bands: CN470 /…
This time I present to you a device that I have long wanted to try, thanks to the company NETIO. In this case I have acquired one of your Smart Sockets, in my case I am in America our electrical network is 110VAC, it is recommended to use the NETIO PowerPDU 4C, perfect for my…
