    • Arduino Options

      Here are some alternative arduino boards that can be used for the wonderful pairing of arduino + nrf24l01.

      For sensor (arduino+nrf24l01 header) - Sensor Node by Elecrow,
      http://www.elecrow.com/wiki/index.php?title=Sensor_Node_V1.2_(ATmega_328)

      For gateway (arduino+ethernet+nrf24l01 header) - IBOARD by Iteadstudio,
      http://imall.iteadstudio.com/development-platform/arduino/arduino-compatible-mainboard/im120410001.html

      Please add any other hardware options you find and that make this project even simpler to implement.

    • RE: Liion batteries

      Battery Options (for sensors, regularly sleeping)
      -1 alkaline battery + Step-up Power Converter to 3.3V
      -2 alkaline batteries in series or button cell lithium battery like CR2032 (3V)
      -LiPo battery (3.7V)
      -3 NiMh batteries in series (3.6V)

      Non-Battery Options (for gateways and repeaters, always on)
      -USB Phone charger + Step-down Power Converter to 3.3V

    • RE: Sound Sensor

      Not sure what happened to the links in the mysensor store but here is the link to the sound sensor you need, make sure it is the one that has 4 pins, with analog output as an option.

    • RE: Gateway for Pachube Or Mysql Database

      Here's how I'm charting the data collected,

      Electric Imp can easily be replaced with arduino with connection to web via ethernet or wifi.

    • RE: PCB Design and Production

      You may want to have a look at this for some ideas or inspiration, it has pro mini and nrf24l01 connections and some of the features you want.

      https://oshpark.com/shared_projects/pRJiKWxV

      $18 for 3 boards, pretty pricey, considering the brains of the system only costs $3 and the nrf only $1.

    • RE: Node external power

      You may want to disconnect everything and just leave the power supply and arduino, then measure the RAW pin and VCC pin, RAW should be anything above 5V, VCC should read 5V for the 5V version and 3.3V for the 3.3V version. Any other readings on VCC suggest that your regulator on the arduino is faulty.

    • RE: VERA 2 Device Install

      Could try reducing the baud rate between gateway and vera. I had trouble communicating with the serial gateway at the highest speed (only 1 way communication), reducing to 9600 solved it.

    • RE: Node external power

      Your pro mini is a 3.3V version or 5V version. If your VCC pin measures a bit over 3V, looks like you are having a 3.3V version.

    • RE: MySensors -> ElectricImp -> Xively

      Here are the results in Xively.
      You will noticed I used the Node ID and Child ID as the Channel name.

    • MySensors -> ElectricImp -> Xively

      MySensors is such an awesome development! Thank you guys, keep up the wonderful work.

      The objective for my first MySensors project was very simple, connect a wireless network of sensors and store the data in the cloud.
      This project involves the following,

      1. Several sensors (temperature, humidity, pressure, light, power)
      2. Gateway
      3. Electric Imp (for wireless connection to internet and Xively)
      4. Xively (for logging the sensor data)

      I do not own a Vera to act as the controller, though I own a Raspberry Pi, seems like there will be alot more development needed for this hardware. Hence, I settled without using a controller for now. Since I just wanted to log sensor data (no actuation for now).

      Modifications needed to MySensors code:

      1. Sensors
        • Since there is no controller to provide the sensor ID, i had to force the ID by entering it in the gw.begin() statement ie. gw.begin(10) for ID 10
      2. Gateway
        • No modicifations needed here
      3. Electric Imp (receive serial comm from gateway and post to Xively)
        • refer to https://xively.com/dev/tutorials/electric_imp/
        • Had to modify the above code to only process serial messages that contain Message Type = 1 (Set Variable)

      Feel free to post your interest and I will be more then willing to share more of my experience.

    • RE: Unable to make it works :(

      also uncomment #define DEBUG in config.h to see more debug messages...
