Howto: Connect IKEA's Trådfri Zigbee Bulbs to a Philips Hue Hub


A lot of boxes.

Written because it pissed me off. I hope this helps you in your hour of need. You have to do one bulb at a time. If you plug in multiple bulbs and try to pair them, it won't work. I don't know why. You will need a portable lamp - or some other way to bring the bulb as close as possible to the hub. Open the Hue app, go through the "Add Device" sequence. The app changes regularly and may be…

Are Brother's Insecure Printers Illegal in the UK?


A padlock engraved into a circuit board.

Another day, another security disaster! This time, multiple printers from Brother have an unfixable security flaw. That's bad, obviously, but is it illegally bad? Let's take a look at details of the vulnerability: An unauthenticated attacker who knows the target device's serial number, can generate the default administrator password for the device. Recently, the UK brought in some laws aimed…

Review: Octopus Home Mini - Real-Time Smart Meter Monitoring


Tiny pink device.

I unashamedly love my smart-meter. Rather than having my energy provider guesstimate my bill, or having to send manual readings each month, it automatically beams them back to its mothership. It also enables interesting things like variable energy tariffs. By design, the smart-meter is limited in how much data it can send back. You can choose to have readings sent monthly, weekly, daily, or…

Why do all my home appliances sound like R2-D2?


Screenshot from Empire. A digital display with red writing.

I have an ancient Roomba. A non-sentient robot vacuum cleaner which only speaks in monophonic beeps. At least, that's what I thought. A few days ago my little cybernetic helper suddenly started speaking! 🔊 💾 Download this audio file. Not exactly a Shakespearean soliloquy, but a hell of a lot better than trying to decipher BIOS beep codes. All of my electronics beep at me. My dishw…

Review: WiFi connected Air Conditioner


Air con unit is 30 cm wide and deep. 70cm tall.

Summer is coming. The best time to buy air-con is before it gets blazing hot. So, off to the Mighty Internet to see if I can find a unit which I can attach to my burgeoning smarthome setup. I settled on the SereneLife 3-in-1 Portable Air Conditioning Unit. It's a small(ish) tower, fairly portable, claims 9000 BTU, is reasonable cheap (£160ish depending on your favourability to the algorithm), …

Gadget Review: 350W Infrared Smart Mirror


Smart Mirror showing the time and weather.

"Mirror Mirror on the wall. What's the hottest gadget of them all?" Do you need a mirror which is connected to the Internet? Yes. Obviously. What's the point of having anything which doesn't have an IP address‽ The good folks at Infrared Group don't want me shivering while I blog, so they've sent me their latest Far Infrared heating panel which, obviously, is also a smart mirror. 350W of heat, e…

Adventures with ultra-cheap ZigBee lightbulbs


3 light bulbs. One is red, one green, one blue.

The people who built my kitchen were idiots. They designed it to be lit with a dozen recessed GU10 spotlights. That's not so terrible - GU10 LED bulbs are only about £1 each - but because I am a bigger idiot, I decided I wanted remote-controlled bulbs. And ZigBee bulbs are expensive! Five years ago, feeling flush with cash, I replaced all the bulbs with a mixture of Hue and Innr Smart bulbs. …

The Fediverse of Things


Binary code displayed on a screen.

One of the most frustrating things in modern technology is the effort spent trying to artificially restrict abundance. Take, for example, this tale from museum-worker Aaron Cope: I was out with a friend who worked for Twitter and I asked them whether it would be possible for the museum to “create 200,000 Twitter accounts, one for each object in the Cooper Hewitt’s collection”. My friend looke…

Receive push notifications from your rice cooker


Android alert telling me that the rice is ready.

I have a lovely, and reasonably priced, Mini Panda Rice Cooker. It does not have any SmartHome features. You put in water and rice, press a button, it cooks rice. Nice! The only problem is - I don't know how long the rice will take to cook. It uses "Fuzzy Logic" to work out exactly how much heat and time is needed for perfect fluffy rice. This is inconvenient. I cannot always hear the beep the…

Mostly These are the Meross 315 Smart Plugs. They are small(ish), cheap(ish), and easy(ish) to use. As soon as I plugged them in, before even configuring them, my home went crazy. I got a p…

Actually, I *do* want IoT kitchen gadgets


Photo of a fridge with a circuit board and sensors plugged into it.

There's a popular meme that Internet connected domestic appliances are a useless fad that no-one wants. I disagree. Obviously, a crappy oven with an app that upsells you cleaning products is a bit shit. As is a dishwasher that borks on firmware update and lets itself be hacked by the Eurasians. But those are just a symptom of profit-led development rather than placing a priority on user-needs. …

Why are there no PowerLine Smart Plugs?


A plug in unit with two ethernet ports.

Another blog post which is a long and complex search query. I have a bunch of smart plugs. Some use WiFi, some use Zigbee, some use Bluetooth. None of them use PowerLine Ethernet. Why is that? I have a bunch of PowerLine Ethernet adapters. They let me use my home's electrical wiring as a network. They also let me plug electrical items into them. But none of them can be controlled remotely. Why…
