Control lights and intencidad with Vera and arduino

  • conde

    Hello I would like to make the following project:

    Control lights and intencidad with Vera and arduino. On, off and control its intencidad . It will be possible?
    Can you help me with components and code?

    Thanks guys.

    Forgive my English , I'm using google translate .

    Yes you can do all of the above,turn lights on/off ,control Intensity and many more things. You didn't say whether you already own a Vera but if you do and you already have some light modules or appliance modules or switch modules then it is a matter of programming your Vera. If you don't have any modules then you will to have the
    1....Vera
    2... Serial or Ethernet gateway that you build yourself
    3... Light dimmer you will build
    4.. Outlet controller you will build
    the list just depends upon your needs and imitation.
    All of these builds are well documented on the Mysensor website.
    So good luck and keep up the dreaming that is where all this stuff comes from someone having a need or a dream or both.

    Hello. Thanks for reply.

    This is my first project witn arduino. I'm learning. xD
    For this project i have:

    • the vera edge;
    • arduino uno;
    • NRF24L01+ 2.4GHz Wireless Transceiver;
    • Relays;

    So my question is. It's possible wiht this components? I need another?

    You say: (All of these builds are well documented on the Mysensor website.) - can you please send me de link? because i can't found.

    Thank you.

    You should use an Arduino Nano for the Vera gateway as it has a hard time recognising the Uno board.

    Are you sure?
    An edge is running ui7 and then a serial gateway will not work. I had one running fine on my VeraLite until I 'upgraded' it to ui7. I never got it working until I built an Ethernet gateway.
    Did this with an uno with 5100 shield. Runs perfectly, still hate ui7 though...

    Have a vague memory they got this fixed in a FW update... Haven't heard any problems from UI7 users lately... so I just assumed it wasn't a problem any more.

    Ok, I missed that news than. Will try that one of these days because have it still laying around. I remember the serial port was there but the device disapeard in the UI.

    Ok, report back.

    It just works now!
    I removed the Ethernet gateway device from the UI and added the new device as per description on the webside. For a short while I had the error ComFailure but found on the forum that in advanced this must be altered from 1 to 0.

    Here is an Example of a battery Operated wireless door sensor it uses a 18560 li-ion battery for power.Wireless_Door_Sensor.jpg Battery_Wireless_Door_Sensor.jpg
    The project cost me about $8-$10.00 to build you might find parts cheaper or have some of your own but this uses a nRF24l01= transceiver and an ATtiny 85 mcu ,2- 22ufd caps a 3.3 volts LDO regulator.
    If interested I can supply BOM and sketch.

    Area in yellow will cut off and the 2 boards will be joined together, to make 1 board.

    Now if you eliminate the 3.3v regulator and run your Attiny off of just the battery you will save about 20ma. Now you will have to place a 1n4007 diode in series with the batteries + terminal and the sensors + input wire, having the cathode of the diode going to the battery +
    I am still working on a way to power down the nRF24l01+ transceiver. I have asked the members on this site for some help with this project..
    now I do power my units with a 5 vdc phone charger so right now I have to leave the 3.3 vdc regulator in the circuit.
    I also have modified the original sketch to put the Attiny85 to sleep for 2 to 4 sec. You would not what the door switch being left unmonitored for more time than that. Now I may also change this to use a pin change to immediately wake unit.
    Here is the code I am running as of now.

    @mntlvr I'm excited to see that mysensors is working with attiny. However, when I compile your code for UNO (can't compile for attiny85 on my IDE), I see the code is about 16kb, much larger than the size of the available memory in attiny85. Did you use a different library?

    Yes a mysensor library written for the Attiny85 chip. And also remember you need to either make a Attiny85 programmer or buy one. I think the 1st choice is the best. There are many articles on the Web that will guide you on how to build your own peogrammer. So do a little research and you will be greatly rewarded. Patience and perseverance will get you what you need and want.
