ATSHA204A implements secured handshake and if handshake fails the Node will not executing any command sent to it 13 | - Programming header is FTDI, TTL Serial. For programming, you need to have USB TTL Serial – FTDI adaptor 14 | - ENIG Emersion Gold finish 15 | - MySensors compatible. You can use superb set of scripts and libraries from [mysensors.org](http://www.mysensors.org) project and convert the node into reliable network of little home sensors, relays and actuators. 16 | - Battery connector CR2032 17 | - You can cut with scissors, sensors and battery holder part of the board, if you need just controller and radio 18 | - Yes, it is open sourced.

HW version is longer range but will eat battery pretty fast though. Please send me message stating which radio type you need in your order. 24 | 25 | ## Overview 26 | If you are familiar with Arduino boards, the ButtonSize Node is Arduino pro Mini with onboard HopeRF RFM69-CW or HW 433 MHz radio, external EPROM flash and crypto authentication chip. To save some board dimensions the ButtonSize Node does not have onboard USB-Serial converter. You need to buy FTDI Adapter for programming. HopeRF RFM69-HW provide extremely good range. HopeRF RFM69-CW version will have half of that range but still many hundred meters in open area. External Flash chip allows burning Arduino sketch wirelessly.

I personally love [Domoticz](https://domoticz.com/) as a smarthome controller. Please check this [HowTo](https://github.com/EasySensors/ButtonSizeNode/blob/master/DomoticzInstallMySensors.md) to install Domoticz. 72 | 73 | - **No Controller setup.** 74 | However, for no-controller setup, as example, you can use 3 nodes - first node as the “Gateway Serial”, second node as a Relay and last one as a Switch for that Relay. No controller needed then, keep the Switch and the Relay on the same address and the switch will operate the relay. 75 | 76 | 77 | Things worth mentioning about the [MySensors](https://www.mysensors.org/) Arduino sketch: 78 | 79 | 80 | Code | Description 81 | ------------|-------------- 82 | Light meter BH1750 Library by Christopher Laws | [MySensorsArduinoExamples BH1750](https://github.com/mysensors/MySensorsArduinoExamples/tree/master/libraries/BH1750) 83 | Temperature and humidity sensor Si7021 SparkFun Library | [SparkFun_Si7021_Breakout_Library](https://github.com/sparkfun/Si7021_Breakout/tree/master/Libraries/Arduino/Si7021/src) 84 | #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 85 | #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. 86 | #define MY_OTA_FIRMWARE_FEATURE
#define MY_OTA_FLASH_JDECID 0x2020 | 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.](https://www.mysensors.org/about/ota)
Skip to the step "How to upload a new sketch just with OTA" as all initial
steps have been completed in the ButtonSizeNode.
For OTA we use JDEC Flash chip where the node stores
new firmware and once it has been received and checksum (CRC)
is correct it reboots and flashes your new
code into the node controller. 0x2020 "Erase type"
defined here for JDEC Flash chip . 87 | #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 88 | 89 | Connect the Node to FTDI USB adaptor, Select Pro Mini 8MHz board in Arduino IDE and upload the ButtonSizeNode.ino sketch. 90 | 91 | **Done** 92 | 93 | 94 | The board is created by [Koresh](https://www.openhardware.io/user/143/projects/Koresh) 95 | 96 | ![enter image description here](https://github.com/EasySensors/ButtonSizeNode/blob/master/pics/bs1.jpg?raw=true) 97 | ![enter image description here](https://github.com/EasySensors/ButtonSizeNode/blob/master/pics/bs2.jpg?raw=true) 98 | 99 | 100 | >For schematics lovers: 101 | 102 | ![enter image description here](https://github.com/EasySensors/ButtonSizeNode/blob/master/pics/schematicNew.jpg?raw=true) 103 | 104 | [**The board schematics Pdf link**](https://github.com/EasySensors/ButtonSizeNode/blob/master/pdf/ButtonSizeNodeNew.pdf) 105 | 106 | -------------------------------------------------------------------------------- /ButtonSizeNode.ino: -------------------------------------------------------------------------------- 1 | /** 2 | * The MySensors Arduino library handles the wireless radio link and protocol 3 | * between your home built sensors/actuators and HA controller of choice. 4 | * The sensors forms a self healing radio network with optional repeaters.
