Home Automation Devices
Several Open Hardware electronics devices based in the SoC ESP8266 for Home Automation.
All designs are made with KiCad, so make sure to have it installed.
In every project you can find the KiCad designs, the manufacturing Gerbers, the necessary firmwares and a documentation folder with BOMs and the design in PDF.
AC Relay
It is a relay controlled by an ESP8266 and a push button. It is powered by the main AC.

Firmwares
Test
This firmware allows you to test the hardware if needed. It will change the relay status each 400 millisenconds when the button is pressed and it will send the push button status via serial communication.
AdafruitIO
This firmware is based in the Adafruit example for comumnicate with its MQTT broker called AdafruitIO. You can see more in io.adafruit.com
In order to use it you should set:
- Your WiFi setting
- You Adafruit user name
- API Key from Adafruit IO
- The MQTT feed which will be used in Adafruit IO
MQTT
This firmware allows you to communicate with a MQTT broker. For example, you can install your own MQTT broker in a Raspberry Pi.
This is the actual firmware that I am using at home with this circuit, and it is prepared for being working 24/7. It does:
- Recovery after a power failure.
- Wake up message
- Reconnect message
- Serial debug
- WiFi reconnect if the signal is lost
- MQTT Broker reconnect if the signal is lost
