BlitzWolf Inexpensive & Compact EU & US Smart Sockets Work with ESPurna & Sonoff-Tasmota Open Source Firmware

BlitzWolf US / EU Smart Socket

When I first started to look into WiFi smart sockets a few years, there were some fairly compact models such as the Linux based Kankun KK-SP3 or ESP8266 based Konke Mini K sockets. In recent years, more wireless smart sockets have come to market, but fewer companies have made compact models, and for example Sonoff S26 or Sonoff S31 smart sockets are not exactly small. But this morning I got contacted by a company called BlitzWolf that sells various accessories including low cost and compact smart sockets for the US and EU markets. It could prove to be interesting, so let’s check out the specifications: BlitzWolf BW-SHP1 US Smart Socket Rated Voltage – 110-240V @ 50-60 Hz Rated Current – 10A (Max) Max Total Power Output – 2000W Dimensions – 4.5 cm ∅ (VO fireproof material) Temperature Range – -10 to +60°C BlitzWolf BW-SHP2 EU Smart Socket Rated Voltage – 110-240V @ 50-60 Hz Rated Current – 16A (Max) Max …

Geekbes BR30 WiFi RGB Light Bulb Delivers 900 Lumens

We’ve previously covered two smart RGB light bulbs with AI Light and Sonoff B1 models, and they are especially interesting since they can work with open source firmware like ESPurna or Sonoff-Tasmota. However, their brightness is limited, and in the case of Sonoff B1 it’s especially true when using colors other than white. A brighter WiFi RGB LED light bulb might be Geekbes BR30 which is said to be rated 9W and delivers 900 lumens against the 6W / 600 lumens for Sonoff B1, and does not cost more much at $19.99 on GeekBuying. Geekbes BR30 specifications: Color – White: 2700K-6500K + RGB (16 million colors) Brightness – 900 lm Light emitting angle – 120 degrees E26 plug Connectivity – WiFi Supply Voltage – AC100-240v 50-60HZ Rated Power – 9W Standby Power – <= 0.3 W Service life –  20000 hours Temperature Range – -20 to +40°C Ingress Protection Rating – IP20 Dimensions –  Ø95 x 116mm Weight – 142g …

Build an ESP8266 IR Remote Control with LOLIN IR Controller Shield for D1 Mini Board

LOLIN IR Controller

Infrared remote control are still widely with TVs, set-top boxes, air conditioners, and all other sort of appliances with the end result of having many remote control around the house. If you want to cut on the number of remote controls, there are several solutions: Get a smartphone with a Built-in IR transmitter like Xiaomi Mi A1. Add an IR transmitter to your smartphones’s headphone jack using ZazaRemote or USB type C port with ROCK USB type C IR transmitter. Get a WiFi IR blaster in order to control devices remotely, or maybe buy several try control any IR devices from anywhere DIY your own solution for more flexibility, for example using ANAVI Infrared pHAT and a Raspberry Pi board. The smartphone solutions (1 & 2) works as long as you are in the room, but the WiFI IR blaster allows you to control devices even if you are not present, or even schedule times to turn the device on …

$10 H801 WiFi RGB LED Controller Supports Sonoff-Tasmota Open Source Firmware

H801 WiFi LED Controller

This week-end, I played with ANAVI Light Controller, an open source hardware solution based on ESP8266 used control 12V RGB LED strips. The board has the advantage of being open source with KiCad schematics, Arduino firmware, and HTML5 server program available, so easy to get started and modify the features as you see fit, and it also supports external I2C sensors via three headers. That’s a low volume project made in Eastern Europe and as a result the board costs $25, so I was shortly made aware there were cheaper solution, and if you are ready to mess around a little bit, H801 WiFi controller appears to be one of the most interesting solution as it sells for under $10 shipped on Aliexpress or eBay, and is officially supported by Sonoff-Tasmota open source firmware. H801 specifications: Connectivity – 802.11 b/g/n WiFi (2.4GHz) with about 10 meter range Output – 5x PWM (R, G, B, W1, W2) each up to 4A, …

ESP8266 based ANAVI Light Controller can be Programmed with Home Assistant or the Arduino IDE (Crowdfunding)

ANAVI Technology previously launched a Light pHAT allowing for RGB Light strip connection to Raspberry Pi boards, and during my review of ANAVI Light pHAT with Raspberry Pi 2, it did the job, but if that’s all you want to do, the  Raspberry Pi board is clearly oversized & overpowered for the job. So Leon ANAVI got back to the drawing board and designed a similar open source hardware board – called ANAVI Light Controller – with an built-in ESP8266 module that removes the need for a fully fledged Linux board. ANAVI Light Controller specifications: Wireless Module – ESP8266MOD module based on ESP8266 Tensilica L106 32-bit processor Connectivity – WiFi 802.11 b/g/n Expansion Terminal block for 12 V RGB LED strip 3x I2C headers for sensors Debugging – UART header Misc – Button Power Supply – 12 V via power barrel jack Dimensions – 75 mm x 40 mm Certification – Open Source Hardware Association (OSHWA) BG000005 The board can …
