@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 :)

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.

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

@hek as I said before, Dallas library is bit outdated.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.

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Replace the libraries that is outdated.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 :)

hek

@robosensor

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

robosensor

@hek I have forked MySensors project, added 3 commits into master branch with updated libraries and updated dallas sensors example (lower power usage).

I'm using similar code in my own version of MySensors 1.5-dev in my home, but I havn't tested this committed 1.4.1 github code on real hardware, so I will make PR after test on real hardware.

Sounds good!

robosensor

@hek It seems that I did it. If this push request is correct, what I should patch? Development branch, master branch or both?

hek

Good!
You can create pull request on master (and I'll merge it to development later).

@robosensor

Thanks and congrats! You've made your first contribution to the MySensors project. :)

Guys, I had some free time tonight and tried to apply this fix... I ended up re-installing the arduino IDE + downloading the latest version, which now is 1.4.1 as opposed to the 1.4 that I used to have ?

Anyways I had to upgrade my ethernet gateway (ENC28J60) and it's no longer working now... any hints will be golden.
LE: I was too tired to check the sketch... I forgot to include the correct library and went to all debugging first, reset router config to default, but in the end I did notice the issue :) So I learned a valuable lesson, never work on this if it's late or you're tired.

CaptainZap

Hello guys,

I really need an expert's opinion on this because I'm experiencing some trouble... I've tried to include suggestions from all you guys, except the delay part, but so far it works partially... in my original code the temperature worked, and now it doesn't. The rest works ok, sensor and motion, so I would be grateful if anyone could take a look at my code and help me with it... I kind of need to get it in place soon, as I intend to leave my house for some time.

Thank you.

@CaptainZap

what does the Serial output show during execution of the sketch?

CaptainZap

@BulldogLowell Unfortunately I don't have a way to test that yet... I'm uploading the sketch using an arduino uno, and I have no idea how to do that with it. I do have an FTDI serial adapter but is not picked up by the IDE, it was at some point but no longer... probably fake :|

I don't know what's the issue, but I'd still prefer a normal timing code instead of just the gw.wait(). The fetching of temperatures in every loop makes no sense to me.
