A first look at GL.iNet GL-S200 Thread Border Router kit with three nRF52840 Thread boards

GL-S200 Thread Border Router review with Thread Dev Boards

GL.iNet are better known for their routers, but the company is also offering IoT gateways and Smart Home hubs such as the GL-S10 BLE to MQTT IoT gateway. The company is now preparing to launch the GL.iNet GL-S200 Thread Border Router in early April, and I’ve been asked to do some beta testing before launch, so GL.iNet have sent me a kit with the GL-S200 and three Thread development boards acting as IoT nodes. A Thread Border Router acts as a WiFi or/and Ethernet gateway connecting to battery-powered Thread sensor nodes equipped with a low-power 802.15.4 radio. In this first post, I’ll go through the hardware and specifications, before reporting my finding in a separate post next week. GL-200 Thread Border Router kit unboxing and specifications The development boards are all identical and they were each kept in an antistatic bag. But let’s open the GL-S200 package first. The Thread […]

SONOFF MINIR4 review – A Tiny WiFi Smart Switch tested with eWelink app/web, and R5 controller

SONOFF MINIR4 wiring

In this post, we’ll review the SONOFF Mini Extreme, also known as MINIR4, WiFi smart switch based on ESP32 wireless MCU by installing it into a wall-mounted light switch box and controlling it with both the eWelink mobile app for Android and the SONOFF R5 scene controller. SONOFF MINIR4 Installation We’ve already gone through the specifications, unboxing, and teardown in the announcement, so I’ll get straight to the installation part. Note this review was done with a light switch “box” (about 11x6cm) in Thailand, so your mileage may vary. The first challenge is that contrary to the similarly-sized SONOFF ZBMINI Extreme Zigbee switch, the MINIR4 WiFi switch requires a neutral cable, and most lights in Thailand are wired without a neutral wire, so I had to get the neutral wire from the outlet switch box underneath. When I call those “boxes” there are really holes in the wall here… Wiring […]

Review of SONOFF ZBCurtain Zigbee Smart Curtain Motor

SONOFF ZBCurtain Review

Recently, Sonoff has released a new Zigbee product – called ZBCurtain – that turns your ordinary curtains into smart curtains. With this product, you can experience new benefits when using your curtains, such as automatic opening/closing, remote control through your mobile device, or setting up advanced automation to control your curtains based on factors such as temperature, humidity, or even using input from the other sensors. These smart capabilities provide benefits for your home or workplace, such as increased safety, energy savings, and convenience. The Sonoff Zigbee Curtain Motor (or ZBCurtain for shorts) can be integrated with your existing ordinary curtains, transforming them into smart curtains that can be controlled remotely via your smartphone, your voice commands, or even from a traditional remote controller. ZBCurtain Unboxing Within the package, we can find a wireless remote control, main motor units with a 3.5-meter long cable, and mounting brackets to attach the […]

SONOFF iHost Smart Home Hub enables local control of SONOFF, Tasmota, Matter home automation devices

SONOFF iHost package

SONOFF iHost is a Smart Home Hub that enables local control of SONOFF smart switches, lightbulbs, Zigbee sensors, and so on without having to require a connection to the cloud (e.g. eWelink).

ZBMINI Extreme Zigbee smart switch review with Home Assistant

Sonoff ZBMINI Extreme Review Home Assistant

SONOFF has rolled out smart switches in the market for years, and for each iteration, they make their devices smaller and more capable. The latest ZBMINI Extreme Zigbee Smart Switch or ZBMINIL2 or ZBMINI Extreme for shorts is what we will review today. Take note that there are both Zigbee and Wifi versions that come with the same form factor, we will walk through the Zigbee version first and we will review the WiFi version – SONOFF MINI Extreme (MINIR4) – later on. The ZBMINI Extreme is designed to work without a Neutral (N) line. Those who have difficulty wiring the N line to the switch will definitely love this. In many locations, the Neutral (N) line is not wired and would require a lot of work and expenses for cabling. SONOFF ZBMINI Extreme eases that challenge since there’s no need for the Neutral wire at all. This review will […]

SONOFF MINI Extreme (MINIR4) ESP32 WiFi smart switch can fit into most gang boxes

SONOFF MINI Extreme

SONOFF MINI Extreme (aka MINIR4) is a ridiculously small WiFi smart switch based on ESP32 wireless microcontroller and designed to be connected to a load such as a light bulb and a wall switch that can be a momentary switch, a door exit switch, an SPDT switch, a latching switch, or even dry contact sensors. The tiny form factor (39.5×33 x16.8mm) enables the WiFi smart switch to fit into various boxes, even the smaller European gang boxes. Just like other SONOFF home automation devices, the MINIR4 works with eWelink mobile app, but it also implements some new interesting features such as the ‘Detach Relay’ mode. SONOFF MINI Extreme (MINIR4) specifications: MCU – Espressif Systems ESP32 dual-core wireless microcontroller Connectivity 2.4 GHz WiFi 4 Bluetooth LE used for pairing Input – 100-240V ~ 50/60Hz 10A Max Output – 100-240V ~ 50/60Hz 10A Max (resistive load) Dimensions – 39.5 x 33 x […]
