A row of recycling bins.

A few years ago I wrote an Alexa skill to see what bin day it was. The skill only worked with my local council – Oxford. I’ve since moved house and wanted to recreate the service for my new council – Bexley. Demo Brilliant, eh? The API Bexley Council don’t publish an API. I initially…

A lot of boxes.

I really wanted to write a rant about how incompatible smart lights are ruining the world. But… errr… Everything just works. Previously on my smarthome adventures, I kitted my house out with LIFX Bulbs and some WisQo Switches. I’ve moved home and none of my bulbs are compatible with the existing sockets! What else am…

Unboxed content.

In my ongoing quest to open my house to hackers create the ultimate smarthome, I’ve added a new toy. A video doorbell! Why? I’ve got a tall house and can’t be bothered walking down several flights of stairs just to tell a peddler to piss off. And, when I’m away, it’s nice to know where…

One evening, my wife turned to me in bed and said, “Winter is coming…” Well, what she actually said was “Get your frozen feet away from me, you cold-blooded monster!” The only way to save our marriage? HOOK OUR BED UP TO THE INTERNET! I couldn’t find an electric blanket with IoT connectivity – so…

I have friends. More than one! I also have a home full of smart-gadgets which are controlled by apps. The two don’t mix. This is yet another complaint about solipsistic app design. Let’s take my Lifx bulbs. I have a friend staying for a few days, and he needs to be able to turn lights…
