Door, Motion and Temperature Sensor

The fetching of Dallas temperature and also the delay(30000) are rather blocking code. Maybe not the cause of your problem, but not very good as a repeater node. Use a timing if-statement instead.

@m26872 No idea how do to that, could you please help me ? :)

[m26872]

Can't guide you in detail right now but this should give you an idea.

Here is an excellent article; How and why to avoid Delay()

[m26872]

Regarding the Vera parental node issue. I see it often but don't know what's causing this. A lot of struggle usually help. I'd try things like:

1. put a "delay(500);" before gw.begin and before gw.sendsketchinfo to make sure radio is fully powered and ready when initializing. Then redo the Vera inclusion. Try a few times.
2. If still no success. Load and run the ClearEepromConfig sketch. Reload your sketch again and continue trying inclusion in vera.

Perhaps you'll get a lot of ghost child nodes to delete. I use static node Ids so inclusion with cleared eeprom doesn't make the controller give me new node ids every time.

@mvdarend @m26872 Thanks so much for your feedback, I did apply the hints and I'll test the sketch later on today. I do have a question... does anyone know how do I upgrade my library to version 1.4.1 ? I've copied the one available from the main page, but it's version 1.4.

Thanks.

DallasSensors.requestTemperatures(); delays code execution up to 750ms. MySensors DS18B20 library is bit outdated, you should update library (https://github.com/milesburton/Arduino-Temperature-Control-Library) and use following code:

In setup:

	DallasSensors.begin();
	DallasSensors.setWaitForConversion(false);

In loop:

		DallasSensors.requestTemperatures(); // no delay here
		gw.wait(750); // insert another value for non-12-bit resolution
		float tempC = DallasSensors.getTempCByIndex(1);

@robosensor Thank you very much for your insight... do I just download the new library and overwrite the one in the Arduino IDE install folder ?

I've also used your code and I'm getting errors compiling it, any hints ? I guess it could be because of the library ?

Arduino: 1.6.4 (Windows 8.1), Board: "Arduino Mini, ATmega328"

@CaptainZap yes, but update two libraries (OneWire and Dallas).

gw.wait() function was added 1 feb 2015: https://github.com/mysensors/Arduino/commit/d45a48d8b786656968fb4b45b049e16700dd3fd0 so you should use latest stable 1.4.* code.

[CaptainZap]

@robosensor I don't know where to find the complete library for version 1.4.x

[robosensor]

@CaptainZap

http://www.mysensors.org/download/ click on Download button under "1.4 - Latest Release" section, download zip archive, extract archive and check Arduino-master\libraries\MySensors\Version.h file.

[CaptainZap]

@robosensor Thanks, I installed that but it's version 1.5 b1 and after using it it's giving me lots of errors :| I think there have been changes in how the code is used...

LE: I finally found the 1.4.1 branch and downloaded it however it's still giving me the same error about wait:

Door_Motion_Temp_rev2.ino: In function 'void getTemps()':
Door_Motion_Temp_rev2:115: error: 'class MySensor' has no member named 'wait'
'class MySensor' has no member named 'wait'

LLE: Just checked the cpp and there is no wait, this is the library I used :
https://github.com/mysensors/Arduino/tree/1.4.1

Can you tell me if there will be any issue if I comment that part ?

@robosensor

LOL :)

[CaptainZap]

That was the version I was using when I first encountered the issues... anyways I'll remove arduino IDE with everything and reinstall it. Thanks.

@hek I also LOL-ed :D Gotta love the helping spirit in the community you guys built.

[robosensor]

@CaptainZap also try to backup and clean C:\Users***\Documents\Arduino\ directory :)

[robosensor]

@hek as I said before, Dallas library is bit outdated. Is it possible to update dallas and onewire libraries? I provided links for newer versions of this libraries in this thread. I can do PR in github myself, but I don't know how to do it :) I need to read github manuals first :)

requestTemperatures() is can be non-blocking in newer version of dallas library, so code can deep sleep (better for batteries) or process messages (better for repeaters and msg-receiving nodes) about 750 ms.

@robosensor

Using github is quite easy (when you get a hang of it). We can use this as a "training session" if you want?

I did a quick getting-started guide here:
http://forum.mysensors.org/topic/330/how-to-contribute-code-to-the-mysensors-project

Basically you need to

• Fork the mysensors project on github
• Clone your fork from your computer.
• Replace the libraries that is outdated.
• Commit as push the changes back to your fork of github.
• Create a pull-request (see above instructions) which I'll review and merge.

Easy peasy.. :)

[robosensor]

@hek thank you, I'll read and try on dallas&onewire :)

@robosensor

Great, just ask (or open a chat) if you run into trouble.
