ESP8266 Multi-relay boards: Sonoff Dual and Electrodragon

 

November was a busy month and the Sonoff Dual that IteadStudio kindly sent me to review was bored in a box waiting for some free time. But it was just fair that another board that has been waiting in the boards-to-review box for longer had it’s chance to have some fresh air too. So here we have the Itead Studio Sonoff Dual and the Electrodragon ESP Relay Board face to face.

The Sonoff POW

Some months ago I wrote about a hack I did to one of my Sonoff devices to be able to use a simple current sensor to monitor my washer machine process and alert me whenever my laundry was done.

A few weeks ago Itead Studio released two new models for their Sonoff line, the POW and the DUAL. And the POW is Itead’s answer to my hack.

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!

Manage and persist settings with Embedis

For months I’ve been searching for a settings manager for my Arduino and ESP8266 projects. There are basically two issues to take care of:

  • On memory settings or how do you access to the configuration values from your code
  • Persistence or how do you store the configuration across reboots
