Control lights and intencidad with Vera and arduino

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.

[hek]

Ok, report back.

[C4Vette]

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.

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.

Conde
Here is an Example of a battery Operated wireless door sensor it uses a 18560 li-ion battery for power.
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.

I would greatly appreciate it. I like your project.

Thanks for your help.

  1-ATtiny 85 chip for each sensor you build
  1-8 pin socket if you wish to make it plug in but can be soldered in directly after you program chip.
  1-nRF24l01+ transceiver for each sensor you build
  1-5pin header female dbl row connector such as http://www.ebay.com/itm/50pcs-2-54mm-Pitch-2X5-10Pin-Female-Double-Row-Straight-Header-PCB-Connector-287-/171275351990?hash=item27e0ce77b6
  or a 4 pin dbl row header connector will do also
  1- case to fit your project
  1-18650 LI-ION 4000 Mah battery and holder if you wish to power in this manner but can be powered by 5vdc 500 Mah phone charger type P.S.
  Now there are other ways of doing this project but I found this works very well for me. There are people on this site that can do it more efficiently than the way I am showing here.
  Good luck with your project and if I can help more just ask.Now plan well , have all of your materials on hand,research anything you are not sure of almost all the answers for any questions you have on the ATiny 85 are on the this site.
  Now you will need a steady hand when soldering the SMD, be patient and be safe with the project .
  I will post a picture of the boards I am wiring. If you use sockets for the ATiny make sure you know where pin 1 is located the sockets are usually maked with a semi circle in the socket but you can put them in any way you choose if you know exactly where pin 1 is located. Same with the nRF24l01= 5 pin or 4 pin just make sure you know where pin 1 is located.

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.
