#4: Making home automation gear quietly

I’ve found that the second-hand Ethernet switches I use in my home automation system have annoyingly loud fans, so I modified them to run the fans more slowly and connect to my Arduino-based environmental monitoring system.

#3: Power-over-Ethernet for Arduino home automation

I’m using Ethernet extensively in my Arduino home automation system for communication with devices distributed around the house, so being able to also provide power to those devices over the same network cable is a big time saver. Until now I’ve been using a “DIY” approach to Power-over-Ethernet (PoE) with midspan injectors sending about 10-12V down the wire, but I’m now converting it all over to use Netgear switches with 802.3af (48V) PoE support built in.

This episode covers some of the options for PoE with Arduino, and demonstrates how you can do it both in a cheap DIY method and using commercial PoE switches.

#2: Arduino-controlled home automation switchboard

The automation switchboards in my house have Ethernet interfaces thanks to an EtherTen (just like an Arduino Uno, but with built-in Ethernet and PoE) mounted inside. This episode shows the switchboard internals, including how the EtherTens switch output loads around the house. It also shows the termination of the house network that starts out as a bit of a mess, but is much neater by the end of the video.

#1: Home automation system architecture

A basic introduction to the approach I’m taking with linking high-voltage devices in my house to the automation system, and how logical inputs are associated with outputs using MQTT.

Apology: The “threat” I attribute to Andy in the video is not something he’s ever said, or something I’d expect him to say. He’s a peaceful soul, and it was purely hyperbole on my part when I was recording the video!
