De-clouding IoT

One of my pet peeves is devices that operate physically within my own house or network, but require an external cloud service to control. There are a big list of reasons why it’s a really bad idea to make your Internet connection a critical part of the control system for the devices around you, which is why a blog post by RevK made me want to stand up and cheer.

I’ve ranted about this on video before, but RevK’s post is definitely worth reading because he lays out the problems and also his plan to “de-cloud” his devices. This is a great idea, and I hope the term “de-clouding” starts to pop up more regularly.

New product: Sonoff Programming Adapter

If you want to load new software onto a Sonoff, you can use jumper wires to link a USB-to-Serial adapter to the programming header of the Sonoff. However, it’s easy to make a mistake, and loose jumper wires can be really annoying.

This cool little programming adapter simply plugs into a common FTDI-type header, and then plugs into your Sonoff.

No more jumper wires. No more looking up the pinout every time you have to connect them!

This little adapter is going to be featured in the next episode of SuperHouse, which will show how to put any Sonoff model (even new ones that haven’t been released yet) into programming mode.

Check it out in the online store.

Setting an Arduino Ethernet MAC address automatically

One of the little time-saving tricks I use in my home automation system is setting the Ethernet MAC address automatically on each device. This saves having to set the address manually in the sketch of every device.

I’ve written it up in a tutorial on the Freetronics site:

Setting Arduino Ethernet MAC addresses manually and automatically

Enjoy!
