Lingan SWA1 Plug in Wi-Fi Socket with MQTT (ESP8266)

This is another cheap plug in Wi-Fi mains socket that uses the ESP8266, comparable to the Sonoff S20. Cost was £8.34 + £2.34 shipping to the UK from TVC-Mall. It is also available from Banggood for a little more and is starting to show up on eBay now too. I didn’t try the standard software/firmware […]

Ai-Light RGBW LED Wi-Fi Light Bulbs with MQTT (ESP8266)

I already had most of my lights converted to RGBW but couldn’t resist getting one of these when I heard they contained the ESP8266 and could be reprogrammed, I eventually ended up with three after buying a second to verify the first was not at fault and then a third to check it was the […]

H801 Wi-Fi RGBW LED Controller with MQTT (ESP8266)

I picked a couple of these up from Aliexpress earlier in the year, I had been planning to DIY something similar but when I spotted these Aiboo H801 RGBWW units for only £8.35 each there didn’t seem much point.  They support the three RGB channels as well as two white channels, up to 96W per channel and […]

Itead Sonoff S20 Plug In Wi-Fi Sockets with MQTT (ESP8266)

Itead have expanded their Sonoff range a lot since I wrote about the original Sonoff module over a year ago. That module has been in use since then and has been rock solid although I did switch from the ESPEasy firmware to Theo Arends’ Sonoff specific firmware, now called TASMOTA which has seen a lot of development. […]

USB Transceiver for 433MHz PT2262 devices

I picked this rather obscure USB device up from Banggood for only £6.69, it can receive and transmit codes for PT2262, PT2260, PT2264, PT2240, EV1527, HS2303-PT and the many compatible devices which means it will work with a huge number of cheap 433MHz devices such as the older OOK Energenie mains sockets and many low cost Chinese alarm sensors. […]

ESP8266 Relay Modules from Itead and Electrodragon

Here are two similar but also rather different WiFi controlled mains switching relay modules that both use the ESP8266 WiFi SoC. Both come with a nice case, can be reprogrammed with your own firmware and are exceedingly cheap for what you get. I’m using these with MQTT and Node-RED so that they seamlessly integrate with the […]

Amazon Echo Alexa Skills Kit integration with Node-RED

I have been using my Amazon Echo and a Raspberry Pi running AlexaPi for voice control of lights, appliances and modes using ha-bridge, a Java app that emulates the Philips Hue API which is one of the few devices that the Echo supports natively. I use ha-bridge to call mosquitto_pub to send MQTT messages to my Node-RED based home automation system which allows […]

Orvibo S20 WiFi Mains Socket with Node-RED

For years I used X10 for all my remote controlled sockets but the unreliability eventually drove me to RF based sockets, the Home Easy ones in particular as you can’t beat the price, often available for circa £20 for a pack of 3 with a remote control and easily integrated into Node-RED and the likes with […]
