The Switch Box is a low-cost wireless Arduino IDE compatible (the Atmel ATMega328P) microcontroller with HopeRF LoRa RFM95 / 69 433/868/915 radio on-board. Best suitable for Home Automation, IOT. It could be used as a switchboard for radio controlling any DIY project. You may think of it as Arduino Pro Mini plus all the items in the picture below:

Features & Specifications

IDE Control:

• Fully compatible with the Arduino IDE
• Enumerates as an Arduino Pro Mini @ 8 MHz
• Compatible with all RFM 69 \ 95 compatible open source libraries available

Radio Transceivers:

Three transceiver options are available - HopeRF RFM95 LoRa® 433/868/915 MHz (long-range version) - HopeRF RFM69-CW 433/868/915 MHz (low power consumption version) - Footprint available for replacing RFM radios with NRF24L01+ 2.4 GHz radio

Security:

• On-board Atmel/Microchip ATSHA204A crypto-authentication chip provides secured handshakes

Antennas:

Tuned PCB antenna options that are soldered to the mainboard - 915 MHz - United States, Canada, Australia - 868 MHz - Europe - 433 MHz - Europe

Interface:

• Long-run soft-touch buttons similar to high-quality home switches
• Each button has a built-in LED for message delivery confirmation
• Reset switch

Power:

Utilizes two CR2032 coin cell batteries - On-board coin cell holders - Reverse polarity protection - High-efficiency power converter - Batteries can last as long as two years with daily use - Battery voltage sensor (via divider) - Sleep current consumption 5uA

Mounting:

Two options are provided for mounting - Adhesive tape on the back - Screws through holes in the backplate - Dimensions 86*86*16 mm

Package content:

• The product comes fully assembled
• No batteries provided.

How to use it as home automation (IOT) node controller

EasySwitchBoxMySensors.ino is the Arduino example sketch using MySensors API.

Burn the sketch into and the switchBox will become one of the MySensors home automation network Node. To create the network you need a controller and at least two Nodes one as a Sensor, relay or switch Node and the other one as “Gateway Serial”. I personally love Domoticz as controller. Please check this HowTo to install Domoticz.
