It's not that other Sonoff products are not “serious” business, but there are a number of design changes in the Sonoff S31 that make this new product a world apart. For the functional point of view it looks like a S20 with POW-powers, but they have redesigned the product completely. The result is very very interesting. Revamped case, more compact and sturdy Redesigned PCB, actually 2 different PCBs for main and control Different power monitor chip: the CSE7766 (same as in the new POW R2) replaces the HLW8012 The only drawback: it's only compatible with plug types A & B, tat is central and north-america and few other countries....

Eight months ago I reviewed and hacked the AiLight WiFi light bulb by AiThinker. By the time there was a number of people doing the same because of a key reason: it sports an ESP8266 microcontroller and it is based on the OpenLight by Noduino, that had already provided open source code for the LED driver inside, the MY9291. Let time pass and I was doing the same with the Sonoff B1 light bulb by Itead Studio....

Six months ago I was reviewing the AiThinker AiLight, a great looking light bulb with an embedded ESP8266EX microcontroller, driven by a MY9291 LED driver. Just before summer IteadStudio released it's Sonoff B1 [Itead.cc] light bulb, heavily inspired (probably same manufacturer) by the AiLight, at least on the design. Now that IteadStudio has become popular between the home automation community you can also find the Sonoff B1 on global marketplaces like Ebay or Aliexpress for around 13€....

A few weeks ago a user came with a request to add support in ESPurna to a power meter that had been hacked by Karl Hagström. It is a very cheap chinese power meter with plenty of room on the inside, enough to house an ESP8266 module and a DC/DC power supply and the main IC protocol had been reverse engeneered. There even was a repository by the Harringay Maker Space with sample code for an arduino compatible platform....

Itead Studio has been releasing interesting gadgets for the Home Automation community based on a low price tag and extreme hackability. You can google “sonoff” (the main brand for Itead Studio home automation devices) to get more than a million hits, including official pages, reviews and lots of hacks. The ubiquitous ESP8266 (or its sibling ESP8285) is the core of all those devices, using WiFi instead of the traditional RF messages, replacing a remote with mobile apps or voice commands....

Following the bright path (sic) of the Ai-Thinker AiLight / Noduino OpenLight I wrote about a few weeks ago, now it's turn for one of those devices you purchase but once they arrive they are stored in the TODO box until they eventually come back to life. The Magic Home LED Controller [Aliexpress, also available from Ebay] is an ESP8266 based single-color RGB(W) LED strip controller. It works with every 5050 LED strip [Aliexpress] out there....
