Sonoff B1, lights and shades

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 closer look at the B1 uncovers some important differences. But before going deeper into the details let me first say that this post will probably look more like a review, at least more than I use to write. And second, yes: ESPurna supports the Sonoff B1 🙂

KK2015 based Ai Light

Really busy these days. I have some drafts ongoing but I wanted to publish this short post right away.

One of the readers of this blog, Michel Clavette, sent me these pics just yesterday. He bought 5 Ai Light bulbs and to his surprise two of them do not have an ESP8266 microcontroller but instead this IC labelled KK2015.

It looks like a drop-in replacement for the ESP8266 since it has the same footprint and all the other components are (apparently) the same. But we have not been able to find even the slight reference to this one on the whole Internet…

So this is an open question: does anyone know about this chip?

UPDATE 20170407: I’ve been confirmed the KK2015 is the very same ESP8266 marked with a different label, reason unknown yet.

UPDATE 20170407 (bis): A new update thanks to a contact  that was involved in design of the Ai Light. The mark belongs to Konke, “a big customer of Espressif, so Espressif provides mark service for Konke in 2016.” So after all, the KK2015 is a rebranding of the ESP8266, nothing more.

Michel will try to flash it using the same procedure as for the ESP8266. Hope we will have some info from him soon.

AiLight – A hackable RGBW light bulb

Some weeks ago a tweet by Manolis Nikiforakis (@niki511) with the #ESP8266 hashtag drew my attention. Manolis had just received a “smart lamp” branded by Ai-Thinker, the AiLight. Yes, the same Ai-Thinker that has sold millions of ESP8266 based modules. Chances were it had an ESP8266 microcontroller inside. Too good not to buy one and take a look at the inside.

Manolis shared the link where he bought his at Ebay for a bit more than USD 10 plus shipping. Unfortunately it’s out of stock there and there are amazingly few other places where you can buy it. I only found the same product with prices around USD 15-18 at Ebay as ESP8266 Smart Home Wifi RGB LED Light [Ebay] or Noduino Open Light LED Smart Bulb [Ebay] also in a cheaper pack of two light bulbs [Ebay]. You can also find it at Aliexpress sold as “DIY Wifi LED Bulb E27 5W AC110-240V lampada LED Dimmable Bulb Lamp Remote Control Led Spot Light for iPhone Android Phones” [Aliexpress]. Don’t you love those seo-ugly names?

I actually bought two because you never know. And they arrived last Thursday. It took me less that 1 minute to open one of the boxes, pop out the cap and take a look at the inside just to see what I already knew. Time to play 🙂
