INTRODUCTION My name is Chaitanya Sharma and I, along with my hackmates, Introducing the Eco Guardian Battery, the next generation of eco-friendly energy storage solutions designed to meet the growing

Why buy and trust when you can build and know?

In my review of Kyvol Cybovac S31 LDS smart robot vacuum cleaner, I noted that app permissions meant both the map of your house and GPS coordinates may be sent to the cloud. But it was pointed out to me

Good Morning! In my previous post on using mqtt with Node-Red, @mytechtrail had asked how to add different tabs for the different flows that could be on separate Pi's. Additionally I'll share with you

Good Morning! Most of my posts have covered the software side of my systems. I did go through wiring up the 12V LED light strips to the Pi with MOSFETS in Part III of the Raspberry Pi Home Automation series.

Good Morning! In my previous post I went over how to install the mosquitto mqtt broker on the Raspberry Pi and a brief explanation of how I use Node-Red to send and receive mqtt messages. In this post

Good morning! In the previous post we went over the setting up of your first flow with Node-Red and my irl brother Randy @mytechtrail shared his first setup. I was going to go through my breadboarding

Good Morning! In the last post we covered how to install or update the Node-Red software in your Raspberry Pi as well as install the dashboard that will allow us to generate those awesome webpages. If

Today I would like to go over how to install the Node-Red software on your Raspberry Pi. The Raspbian Operating System comes with Node-Red, but I'm not sure what version, or if it includes the Raspberry

In my fifth post we went over the basics of Node-Red, how to install it in a Raspberry Pi and some of the webpages generated by it and the controls utilized on the dashboard. Today I want look a bit deeper

In part 4 of this series I shared some pictures of the LED light strips in action and the small relay board that I use when I want to control a device with power that is independent of the Raspberry Pi.

In my first post I went over the layout of my Raspberry Pi home automation system. In my second post I went into a little bit more detail on the Power Supply and Raspberry Pi. In my third post I described

In my second post I shared how easy it was to recycle an old PC power supply. Just don't forget the fuses, my PS can deliver 5V @ 15A & +12V @ 16A & 18A, more than enough to damage your circuits

In my previous post, I showed the entire Raspberry Pi circuit, including the power supply, Pi, MOSFET Switch Board & the Relay board. Today I'll show close up pics of the Power Supply and the Pi. I'm

在挖坑第一步里已经给树莓派装好了mqtt，那么这次就是要让温湿度传感器通过esp8266这个无线模块，把数据传给树莓派，以便后续在HomeAssistant中的自动化处理。 与ESP8266作MQTT协议传输温湿度数据，根据室内外温度情况自动开启空调或配合天气情况开关房间顶灯等。。。

Finalmente dopo aver combattuto per settimane e mesi ci siamo arrivati! La XDK di Bosch sta inviando dati in JSON tramite MQTT al Tangle di IOTA via MAM. Ringrazio Come prima cosa ringrazio: Rck - per

今天本来是没有时间写的，各种巧合吧，很高兴的来写了。 一是不知怎么的就把自己的开发环境搞崩溃了，可能受不了我的折腾吧，所以在重新下载，重新安装。这都需要时间，恰好用这段时间写一点。 二是之前说的淘宝争议淘宝判我胜诉了，拿到1500的小钱钱，心里还是很高兴的。 刚才一打开，发现 @tumutuazi
