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… Continue reading →

An error message in the browser warning of an unsafe SSL connection

Me being grumpy and stupid again. I have an IP Camera on my LAN, I want to connect to it via HTTPS. I can't. Why is that? Why do this? I have a username and password to access my IP camera. And my TV. And my lightbulbs. And all my networked gadgets. If I try… Continue reading →

What if your Internet Connected Fridge came with free electricity?

A bit of future-gazing which I can't be bothered spinning into a 15,000 word Gartner report. In the UK we have a competitive electricity market.

The good folks at Sonoff have sent me a review unit of their "7.0" Nextion Enhanced HMI Capacitive Touch Display with Enclosure". A… Continue reading →

I've been sent a couple of Sonoff smarthome gadgets. You can read my review of the S20 WiFi plug socket and the POW in line power controller.
