Gadget Review: DophiGo DV-200 WiFi Doorbell


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 couriers are leaving my packages. So, here's my review of the DophiGo DV-200. It was £40 on special offer. One thing to note - this is an energy efficient unit. There's no PIR sensor or movement detector. It …

Tado API Guide - updated for 2019


Debug screen of a web browser.

Tado is a brilliant smart thermostat. But their API is very poorly documented. This is an updated guide for 2019. I am indebted to Stephen C Phillips' original documentation. Getting started You will need: A Tado (duh!) Your Username (usually your email address) Your Password A Client Secret Getting the client secret I'm using this client secret: wZaRN7rpjn3FoNyF5IFuxg9uMzYJcvOoQ8QWiIqS3hfk6gLhVlG57j5YNoZL2Rtc This secret may change in the future. In the examples, I'll shorten it to…

Building an Alexa-Powered Electric Blanket


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 built my own. Why? As a person with cold feet, I want to yell at my robot servant to pre-heat the bed, so that it is toasty warm by the time I've finished my evening ablutions. The Blanket …

Review: Meross Smart Lightbulb - MSL120


Product shot of the lightbulb.

I've previously reviewed other Meross smart home devices, so now on to their MSL120 - an E27 screw cap bulb. The bulb has dimming and colour changing functions. Let's crack on with a video! The app The Android app looks good - although a little rough around the edges, but it's easy to set up a bulb and control it. Controlling the colours and brightness is a little odd. You have to slide your finger over the whole screen. Vertical for brightness and horizontal for colour. There's…

There's no HTTPS for the Internet of Things


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 to enter the passwords on a modern browser, I get this error message: It is now an accepted fact that data should be encrypted during transport - even on a trusted network. I have a modest home network of several dozen gadgets -…

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. Only one set of wires comes to your house, but you can buy your electricity from a number of providers. Some only offer organic, corn-fed, Wind Farm power - others promise price stability - another gives you a discount at their electric car chargers - one gives you loyalty points at a supermarket. We increasingly have smart meters. Second-by-second…

Review: Sonoff 433 RF WiFi bridge


The good folk at Sonoff have sent me yet another gadget to review. This is a slightly curious device - an IP to 433MHz remote. This allows a smartphone to control smarthome gadgets which usually require an RF remote control. It costs £8 plus postage direct from Itead. This is similar to an Infrared device I reviewed a few years ago. It's a cute little box, small and light enough to hide away anywhere. Even under use, it doesn't get hot. Note - it only connects to 2.4GHz WiFi. That's …

Review Nextion HMI Touchscreen with GPIO


I don't think the people who sent me this touchscreen are going to be very happy with this review. But that's the peril of asking bloggers to assess your kit, isn't it? The good folks at Sonoff have sent me a review unit of their "7.0" Nextion Enhanced HMI Capacitive Touch Display with Enclosure". A USB powered touchscreen - with a range of hackable goodies. It's a device which sadly fails to live up to its promise. Specs Let's get the specs out of the way, then see how it works! …

Alexa powered smarthome control for Sonoff


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. Here's a video of me controlling them from my Amazon Alexa: The latency seems a little slow - hard to tell if that's Amazon only relying on US data centres for Alexa skills, or the connection to my home. Once set up, it works well. Oh... but the set up experience... Set Up I'll be honest - configuring a smarthome for voice control is still …

Review: Sonoff Pow - WiFi power switch and monitoring


The good folks at Sonoff have sent me a bunch of kit to review. See my previous review of the S20 WiFi plug. This is the Sonoff Pow - a WiFi enabled in-line power switch. Set Up Wiring up the Pow is relatively easy. The cover to the terminal block is secured with a simple screw. I found the opening a little cramped - but it's easy to open up the entire unit. Which gives us a full view of the circuitry. There's an unpopulated header on the bottom left - yup - this thing is hackable! A …

Review: Sonoff S20 WiFi Plug


A schematic of a smart plug.

The good folks at Sonoff have sent me a bunch of kit to review. First up, the S20 WiFi Plug - an easy way to retrofit IoT smarts to your existing appliances. This fills the same niche as the Belkin WeMo but with one crucial difference - it's about half the price. Direct from Sonoff it's US$13 - from Amazon UK the smartplug is £15. The cost of the WeMo is £40. How does it compare to the Belkin WeMo? Both are compatible with IFTTT, have 2.4GHz WiFi, and have buttons and status LEDs. The …

Internet Connected Lightswitches - Redux!


Regular readers will remember that I have had a disastrous experience with WiFi light switches. I've had pretty good results with LIFX bulbs - but I really wanted something which can control my lights' switches. Enter the new WisQo smart lightswitches. The company claims that they'll work with the UK's "unique" wiring designs. They've kindly sent me a set to review - adjust your bias filters accordingly. The good news is they actually work! The bad news is that the app is tedious to use.…
