A few posts ago I showed how to measure power consumption with Shelly’s IoT device. In this post I’m going to share my measurement results regarding my PC and my Playstation 5. I measured the total power draw of these devices directly from the socket.

I’d like to share this picture, I shot this in a village near Budapest. It represents the Hungarian ‘jólvanazúgy (TM)’ philosophy perfectly (if you don’t know just google it). Yes, it’s a splice enclosure just hanging freely in the air. I’ve have seen some bad…

I have made some test measurements with a network analyzer, I would like to share my results and experiences in time dimensions measurements. Instead of making measurements in frequency domain sometimes it’s worth switching into time domain. Newer network analyzers usually support this function, it’s…

I’ve been practicing IOS commands recently, I have created a single area OSPF network with an ASBR router in Packet Tracer. Just like in the previous post I’m going to share the commands I’ve issued on the routers with some explanation in order to remember…

In the following I’m going to share one of my Cisco Packet Tracer practices. To memorize and practice some basic IOS commands I’ve created the network below for myself. Because I’ve saved every command I thought to share it on my blog since it might…

In this post I would like to show you how to set up the firewall of your VPS and restrict its SSH access from zero. This is the way I do it, it doesn’t mean it’s the only viable solution, it can be done by…

In the following post I would like to introduce you Shelly’s IoT device called Shelly PlugS. With the help of this device we can turn on/off devices we’ve plugged into our socket and we can monitor the power consumption using MQTT protocol. Configuring the Shelly…
