Sonoff TH10 & TH16: sensors, displays, actuators,…

Itead Studio keep on creating interesting products for the hacker community. A few weeks ago a new version of the already classic Sonoff TH came to life. This new version comes in two flavours: the Sonoff TH10 and TH16 and you can buy them at Aliexpress: Sonoff TH 10A/16A Temperature And Humidity Monitoring WiFi Smart Switch.

In this article I will briefly talk about what’s new in this device to quickly go to explore one of those novelties: it’s external interface.

4Duino-24 upside down

A few weeks ago the 4D Systems announced one of its latest products: the 4Duino-24, an Arduino compatible display module with built in 240×320 resolution TFT LCD Display with Resistive Touch and an ESP8266 ESP-06 module on board.

it looked like a great product for a home automation control panel, although the screen could have been bigger. Anyway I contacted the people at 4D Systems and they were kind enough to send me a sample to review, and hack!

Your laundry is done

Have you ever forgotten your wet clothing inside the washer for a whole day? I have. Even for two days. They smell. You have to wash them again and you know you might end up forgetting about them again!

Actually that is happening to me since me moved to an old house in a town north of Barcelona. Instead of having the washer in the kitchen, like we used to, now we have it in the cellar, in a place I don’t normally pass by to notice the laundry is done.

So I started thinking about monitoring the washer to get notifications when the laundry is done. And since I was at the same time playing with ITead’s Sonoffs, which has an AC/DC transformer and a powerful controller with wifi, it looked like a nice project to put together.

Adding RF to a non-RF ITEAD Sonoff

Yes, sure! You can buy a Sonoff RF and you are good to go, I guess. But I didn’t and I was not so sure about the no-named RF receiver so I ended thinking about adding my own.

But first things first. The Sonoff is an ESP8266 based smart switch by ITEAD which comes with a custom firmware that communicates with the manufacturer cloud to provide “smart” capabilities like remote switching or scheduling. The cool thing is that it has a line of pins that expose the VCC, GND, RX and TX pins of the ESP8266 and a buttons attached to GPIO0 so very soon it got hacked and there are a number of firmwares already available. I’m not an early adopter and some work has been done and reported by Peter Scargill, Javier or even in instructables.
