Xiaomi Smart Display Switch 2 brings a colour screen and mmWave radar to wall switches without a neutral wire

Most wall switches with a colour screen need a neutral wire, because the display has to be powered all the time. Xiaomi's new Smart Display Switch 2, listed in China on 28 October 2026, tries to get round that. It works with or without a neutral, and in single-wire installations it runs the screen from a built-in energy store. Crowdfunding opens on

How to choose a smart plug with local control and energy metering

A smart plug is the cheapest way to automate something and the easiest way to find out what a device really uses. It is also the product category where it is easiest to buy the wrong thing: a plug that only works through an app and a remote server, a relay too weak for a heater, or a metering chip that reports once a minute when you wanted live dat

LoRaWAN at home: when long range makes sense and how to start with The Things Network

Wi-Fi does not reach the bottom of the garden. Zigbee needs a chain of mains-powered routers to get to the shed, and there is no socket at the gate or the rain barrel. This is where LoRaWAN earns its place: a battery sensor that sends a few bytes from hundreds of metres or even kilometres away and runs for years on a pair of cells. It is not a repl

Wi-Fi HaLow in Europe: what long-range Wi-Fi can do for IoT and where it falls short

Wi-Fi HaLow promises something that sounds ideal for a house with a large garden, a detached garage or an allotment: Wi-Fi that reaches about a kilometre, passes through walls and runs a sensor on a battery for months. Modules, Raspberry Pi add-on boards and small routers have started to appear. Before you buy, though, it helps to know that HaLow i

Zigbee2MQTT without Home Assistant: run it in Docker with Mosquitto and control devices over MQTT

Zigbee2MQTT is best known as a Home Assistant add-on, but it does not need Home Assistant at all. At its core it is a bridge: it talks Zigbee to your sensors, bulbs and switches through a USB or network adapter, and publishes everything as MQTT messages. Anything that speaks MQTT can then use those devices: Node-RED, openHAB, a Python script, an ES

MQTT topics, QoS, retained messages and Last Will: design messages that hold up

Getting a sensor to publish to an MQTT broker takes a few lines of code. Getting a whole house of sensors, switches and scripts to talk over MQTT without stale values, lost commands and devices that look online when they are not takes a little more thought. Four features decide most of it: topic structure, Quality of Service (QoS), retained message

Store and chart MQTT sensor data with Telegraf, InfluxDB 3 Core and Grafana

An MQTT broker only passes messages along. Once a temperature reading has been delivered, it is gone, apart from the last retained value. If you want to see how the living room temperature changed over the past week, something has to subscribe to the topics, store every reading with a timestamp and draw a chart from it.
