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, […]

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 […]

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 […]

Review: Matter-enabled Energy Monitoring Smart Plugs - Meross 315


Two plugs side by side.

Matter is coming to fix all your smarthome woes! A single IoT standard, working across multiple radio protocols, bringing together different products from many different manufacturers. And… it works! 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 […]

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 […]

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. […]

My Underkill Home Network


A complex graph with dozens of devices connected by a tangle of coloured lines.

There's an absolutely delightfully bonkers post doing the rounds called "My Overkill Home Network" - which is a look into what happens when a computer geek goes feral and stuffs as many Internet connected thingamajigs in a living space. We're talking professional grade, rack mounted, doubly redundant, over-specced, equipment. Overkill is underselling it. I wondered […]

Zero Interfaces


R2D2 interfaceing with the Death Star.

The best gadget I got in lockdown was a set of motion activated lights. They have no user interface. I walk by them in the dark and they turn on. Midnight piss? No fumbling for a light switch, no shouting to a digital assistant, no logging in to an app. Simple. I love it. It […]

Adventures in home automation - Home Assistant on a Raspberry Pi 2


Screenshot of a website with loads of toggle switches.

They say that The Best Camera Is The One That's With You - the same is true of Raspberries Pi. As much as I'd love a 4B, they seem permanently sold out. So I dug through my scrapheap of old tech and resurrected an ancient Pi2. It's old, outdated, slow, with limited RAM, and has […]

Lessons learned from a power-cut


Photo of an MCB - a small electrical switch. It is in the off position.

The first indication I had that anything was wrong at home was my solar panels's cloud service casually emailing me to say they hadn't generated any electricity that day. We were on holiday - literally on the other side of the planet - and there were reports of snow at home, so I didn't think […]
