Hi all. I have been searching for a way to power nodes and stumbled across this project. My question is is this a viable and safe solution if I just recreate the ac-dc portion on perf board? In essence I want to create a good 5v power supply that can be hardwired into my home inside of an electrical box. Not necessarily in the wall but in less accessible places like attics and such.

Sorry to leave you hanging for so long. Was finally able to start my troubleshooting of the node today. Turns out it did end up being a wiring issue, filed as "Technician Error". Rather than having both the reed switches share a common ground, I had one sensor grounding to the data pin of the other.

@mfalkvidd thank you. I was disappointed when I sat how it formatted. I will check your suggestions today.

Hoping for some help from the MySensors experts. Im running a home automation system using Domoticz as my controller and MySensors 2.0 Library for my nodes. I noticed the close proximity of my front door and my garage door and wanted to save a microcontroller and radio by having it handle the reed switches for both doors. First off I do not consider myself a coder Im much more of a hardware kind of guy. I ended up cobbling this sketch together by looking at an example I found in the forums and looking at the included binary switch sketch.

My issue is when I open the front door, both the garage door and front door indicators on my Domoticz dashboard change state. When I open and close the garage door only the garage door indicator changes state. I suspect it has something to do with how the pin ID's are assigned but I just am not very strong in that department. Any help would be appreciated.

@tlpeter I had not, thanks so much! I'm still a novice when it comes to GitHub, how do I download the files?

hmm... is it possible I somehow got an incomplete library? I only have 4 sketches that begin with D and none of them are that one.

I wanted to update all my sensor to the 2.0 library but Im noticing that the Humidity sketch seems to have been removed. Is this correct?

@tbowmo I deleted all the files and reinstalled the Arduino IDE. Placed the library as you said and everything works! Thanks and sorry for the inconvenience!

So first I tried placing the entire folder in ~/Arduino. No luck there. Then left that folder where it was and copied the Libraries folder from Arduino-Master into ~/Arduino/Libraries. No luck. Nothing was showing up under sketchbook either.

I then placed the Arduino-Master in ~/sketchbook and that allowed me to see the library in the Arduino IDE but I still get the same error. I then copied the Library folder from Arduino-Master into ~/sketchbook/libraries and still came out with the same error. Im considering doing a fresh Arduino IDE install.

Running Arduino IDE version 1.6.9 with the newest MySensors Library and Ubuntu 16.04

Hi Guys,

I am struggling to import the MySensors library into Arduino IDE. I have spent the last two days googling and trying things to no avail. I am running Ubuntu 16.04.

I have the Arduino IDE installed ant it is functional. I can upload one of the example codes to a Arduino MicroController and it works. I can even see the MySensors Library under sketchbook. The problem arises when i try and use any of the codes bundled in the MySensors library. When I try and verify the code I get the following error...

Arduino: 1.6.9 (Linux), Board: "Arduino Nano, ATmega328"

/home/dane/sketchbook/Arduino-master/libraries/MySensors/examples/HumiditySensor/HumiditySensor.ino:31:24: fatal error: MySensor.h: No such file or directory
#include <MySensor.h>
^
compilation terminated.
exit status 1
Error compiling for board Arduino Nano.

Any help would be GREATLY appreciated.

@sundberg84 sorry to be such a pain but I'm not understanding. Do I add that to the node sketch? When I do I get "null was not declared in this scope".

Also looking at domoticz log is there a way to know for sure that domo and my gateway are communicating?

Thanks in advance for your help!

@sundberg84 where do I add this code? I'm having the same problem

@app-z.net where does this code need to be entered?
