### The Wall Socket Insertable Node  is extremly low profile wireless 220 Volts 10A Relay board. It is suitable for installing into wall socket compartment in between the socket and the wall.The board Height is  only 13mm. It is Arduino IDE compatible (the Atmel ATMega328P) microcontroller with RFM 69 HW radio on board.  Onboard 220 Volts power supply. Secure athentication with ATSHA204A crypto-authentication. Best suitable for Home Automation, IOT. Current sensor can report power consumption. One Pixel LED installed and one regullar LED can be connected. External button connector. You may think of it as Arduino Pro Mini plus all the items in the picture below:

How to use it as home automation (IOT) node Relay
------------------------------------------------------

wallSocketInsertableNode.ino is the Arduino example sketch using [MySensors](https://www.mysensors.org/) API.

Burn the wallSocketInsertableNode.ino sketch into it and it will became  one of the MySensors home automation network Relay Node. The Relay could be controlable from a smarthome controller web interface or smarphone App. 
To create Home Automation Network you need smarthome controller and at least two Nodes one as a Sensor, relay or actuator Node and the other one as “Gateway Serial” connected to the smarthome controller. I personally love [Domoticz](https://domoticz.com/) as smarthome conroller. Please check this [HowTo](https://github.com/EasySensors/ButtonSizeNode/blob/master/DomoticzInstallMySensors.md) to install Domoticz.

However, for no-controller setup, as example, you can use 3 nodes - first node as “Gateway Serial”, second node as the Mini Relay Box node and the last one as switch for the relay node. No controller needed then, keep the switch and the relay node on the same address and the switch will operate the relay node.

Things worth mentioning about the  [MySensors](https://www.mysensors.org/) Arduino sketch:

Code |	Description
------------|--------------
#define MY_RADIO_RFM69 #define MY_RFM69_FREQUENCY RF69_433MHZ #define MY_IS_RFM69HW|	Define which radio we use – here is RFM 69 with frequency 433 MHZ and it is HW type – one of the most powerful RFM 69 radios. If your radio is RFM69CW - comment out line with // #define MY_IS_RFM69HW 
#define MY_NODE_ID 0xE0 | Define Node address (0xE0 here). I prefer to use static addresses and in Hexadecimal since it is easier to identify the node address in [Domoticz](https://domoticz.com/) devices list after it will be discovered by controller ( [Domoticz](https://domoticz.com/)). However, you can use AUTO instead of the hardcoded number (like 0xE0) though. [Domoticz](https://domoticz.com/) will automatically assign node ID then.
#define MY_OTA_FIRMWARE_FEATURE #define MY_OTA_FLASH_JDECID 0x0 | Define OTA feature. OTA stands for “Over The Air firmware updates”. If your node does not utilize Sleep mode you can send new “firmware” (compiled sketch binary) by air. **Here is the link on how to do it.** For OTA we use JDEC Flash chip where the node stores new firmware and once it received and controlsum (CRC) is correct it reboots and flashes your new code into the node controller. So we define it is "erase type" as 0x2020 here. 
#define MY_SIGNING_ATSHA204 #define MY_SIGNING_REQUEST_SIGNATURES | Define if you like to use Crypto Authentication to secure your nodes from intruders or interference. After that, you have to “personalize” all the nodes, which have those, defines enabled. [**How to “personalize” nodes with encryption key**](https://github.com/EasySensors/ButtonSizeNode/blob/master/SecurityPersonalizationHowTo.md). You need both defines in the nodes you need to protect. The Gateway Serial could be with only one of those defines enabled - #define MY_SIGNING_ATSHA204
#define AdafruitNeoPixel | Enables onboard Pixel LED SK6812mini

Connect the Relay to FTDI USB adaptor, Select Pro Mini 8MHz board and burn the wallSocketInsertableNode.ino sketch.

**Done**
