I started a project with Mysensors to automate some parts of my home, I made the first gateway with Arduino and an ethernet shield.

My goal was to have a 220V controlled by Vera Lite.

What you need:
-Arduino Nano
-Radio module NRF24L01 +
-capacitors
-resistances
-breadboard thousand holes
-Relay Module 10A
-cables and plugs

The wiring diagram.

is important to the condensoatore of VCC and GND of the radio to the stability and the good reception of the same.

Here's my self-built PCB

we put it all in a box of Gewiss 8cm x 12 cm

We insert the power supply

finally finished work:

Vera display

Link code

Thanks to All

Hay!!!

This is MyAirwik Sensor

Voltage measured!!!

On Vera lite!!!

Battery Version!!!!!

@cdrum I tried with many arduino nano purchased on ebay but I could not connect on vera.

Try with gateway Ethernet !!!

@Petjepet I Know, thank

on board as I did your chart

Thank
