Another thing that I've thought of is removing the RTC module completely since we can query the time from the server periodically.
This would save components and pins, but it would limit the clock to only working with the controller, whereas the current design allows it to run independently
The method Check_KeyPad (Line 300) handles the buttons.
Currently my buttons do the following
@dbemowsk
To use a 24 hour clock switch the following bool
bool Screen_HourFormat24 = false;
I think I used the colon to signify that an alarm was set, I think I flashed it on and off. in the Update_Screen method
if ((Alarm1_Enabled) && (!Keys_ShowAlarmOnScreen)){
if(Screen_ClockPoint)ledScreen.point(POINT_ON);
else ledScreen.point(POINT_OFF);
} else
ledScreen.point(POINT_ON);
I often wish our fancy mysensor nRF chips only used 1 arduino wire 
I found a library online.... #include <AnalogMatrixKeypad.h>
I made some modifications (although I can't quite remember what they were), I think about the number of buttons, or combinations, or target values.
But generally the library provided the 1 wire, resistor ladder and debouncing functionality I needed
@Nca78
exactly correct.
I originally went with the same resistor value so that it was easy. But then when I thought about how many button combinations I wanted (thinking about a real clock where you hold down the alarm set button then press the hour button) I went with different values.
My implementation still isn't perfect, since I'm a bloody amateur... lol. I think 1 or 2 of the combinations I never got working.
But for the most part it accomplished what I wanted... provided many buttons and combinations on a single input pin, since I was quickly running out of them
Here is a project I finished this weekend.... 5m LED strip controller (the cover is off for the photo)
I think you can say I've come quite far since my first ever arduino build... lol

@maghac Great project.
I've made something similar, Arduino Pro Mini 5v, 5m LED strip (non-addressable), nrf24L01+ and MOSTFETs
I know it took me awhile to find code examples, so I figured I would share my code incase it helps anyone else.
I use Domoticz as a controller. This code talks to:
Much of my code is standard stuff, using FastLED analogue, but I'm particularly proud of the brightness part, since I bashed my head against the keyboard several times trying to figure it out

Hopefully this proves useful to someone 
Hey everyone.
Sorry, had a computer crash and file loss issue a few months ago.
I can't find my final code file, but I did find an older version (incomplete) called ClockRebuild.ino and I uploaded it to the project.
Hopefully that helps
One day I'll come back and truly finish this project, life just keeps getting in the way
@gohan maybe, I don't know, I only pretend to be an electrical engineer in my spare time... Lol
I'm actually working on something similar right now. I also ripped apart my remote control.
Originally I was planning on getting a radio transceiver set to read and then mimic the remote codes, but I couldn't get it working.
So instead I'm in the process of connecting the remote board Frankenstein style to an arduino with transistors and stuff.
The remote board has contact patches for all the buttons, and if you connect them to ground it triggers that specific button.
So my final build will have the remote control board, a pro mini, nrf and other parts all cobbled together and stuck in a box on my nightstand. From there I can use my phone domoticz app to control anything.
I'm also adding a temperature sensor so I can automatically control the fan based on room temperature.
It may have been this project I forked, I can't remember https://github.com/Danimal4326/homebridge-ecoplug
I have the same plugs (Eco Plug I think)
I use domoticz on a raspberry pi for my mysensors and other stuff.
I didn't hack mine, I just forked a homebridge plugin (it was either python or node based, I can't remember) and got it working on my domoticz
@pansen I've burned out a couple nano's and pro mini's by supplying what was supposedly 12v from a wall wart.
So I would advise using a linear voltage regulator
Nice build, and great idea using the ultra sonic sensor.
This sort of thing was the exact reason I got into arduino and eventually mysensors. I had a concern about a damp basement and went looking for a water leak detection alarm but the prices were so high at the time... eventually I stumbled upon arduino and the obsession went from there.
The first node I ever made was a water leak detection system that used the 4cm thing mentioned above... then I realized I had all these left over pins 
so I filled them up with a gas, flame, temperature, humidity and light sensor.
Forget nest protect and commercial water leak detection systems... I now have an all in one DIY solution that probably only cost $30
I've fried a couple pro mini's and a nano running 12v to the vin/raw... actually in one case it might have been up to 15v .... oops.
But I've since learned my lesson.... I now use a Linear Voltage Regulator between the source and the arduino for all my builds that have a higher voltage power source (i.e.: builds that run lights). Typically a L7805CV or L7809CV or L7810CV (or other) depending on the voltage of my source and what I want to send to the arduino.
Here is an example L7809CV from AliExpress
I've finally settled on an enclosure design for my first (of 3) clock. This one is for my 10 year old son, I think he's going to love it.
I originally found this on pintrest....
I'm going to use the bomb idea but modify it to fit all my existing design elements.
I'm currently awaiting some parts from aliexpress and I'm still trying to find materials for the dynamite sticks. Hopefully I'll have everything I need soon so I can start to build it
@Oitzu said:
The RAW pin runs into the oboard voltage regulator and can be feed 3.3V - 12V (Be aware that most china clones don't withstand the full 12V)
I can attest to this fact, since in the last few weeks I fried 3 clones building my 12v led controller before realizing they just can't handle 12v on the raw/vcc pin.
I'm looking for an answer to this too... My nodes sometimes have trouble connecting on boot... And it seems like they won't do anything until they make the connection to the gateway.
Is there an api function I'm missing that lets the node continue attempting to connect in the background after x number of tries while still letting the node do it's own work?
Eventually I'm going to make a case/enclosure for it.
I don't want to make it boring, like a basic alarm clock rectangle.... instead I want to build it into something... kinda like this stereo in a mannequin I found on Pinterest
or like this clock in an NES
Although since it's for kids I'll probably use a toy dinosaur or something
@hek
thanks!!!!
I've got a bunch of other things I want to add to it...
I'm really excited about adding @petewill 's Bed-Occupancy-Sensor... I've got two kids (and I'm planning on building them both a clock)... and they are at my house 50% of the time... so I want the alarms to go off on school days, but only when they are at my house.
So I plan on using the bed occupancy sensor to cancel the alarm if no one is in the bed.
On the flip side, if the kid turns off the alarm, but doesn't get out of bed within a set amount of time, I want the alarm to go off again... kinda like a forced snooze.
I also want to add an SD card and mini amplifier (LM386) so I can play their favorite song as the wake-up music... but I've got to wait for my aliexpress order of the LM386 to arrive (in 30 to 60 days...lol)
@hek
Thanks!!!
I've been stalking the forum and asking beginner questions for at least a year now... I've learned so much and am so grateful for everyone's help... Now I've finally got a project close to completion, so I thought it was about time to try and give back
Plus by sharing, the super smart forum members like yourself will probably tell me where I messed and could have done better... lol
Oh, I didn't know I needed to use both.
Well I tried a million combinations after seemingly reading everything on the subject, and I still couldn't get {int + char + int} converted into a char[] using strcpy and strcat
for some reason my brain is just not wrapping itself around the concept today... maybe I'll come back to it tomorrow.
In the mean time, I tried the following and it worked.
char buf[20];
sprintf(buf, "%d.%d", Alarm1_Time_Local[0], Alarm1_Time_Local[1]);
send(MySensors_MSG_Alarm1_Time.set(buf), true);
I've read that using sprintf increases the size of your sketch... but for now I'm fine with it, since it works and I can move on to being creative and productive.. lol
@hek
Ok, I think I understand what you are saying, but I can't figure out the implementation.
This didn't work
char temp_Msg[3];
strcpy (temp_Msg, char("1"));
strcpy (temp_Msg, char("."));
strcpy (temp_Msg, char("1"));
send(MySensors_MSG_Alarm1_Time.set(temp_Msg), true);
or this
char temp_Msg[3];
strcpy (temp_Msg, "1");
strcpy (temp_Msg, ".");
strcpy (temp_Msg, "1");
send(MySensors_MSG_Alarm1_Time.set(temp_Msg), true);
or this
char temp_Msg[3];
strcpy (temp_Msg, '1');
strcpy (temp_Msg, '.');
strcpy (temp_Msg, '1');
send(MySensors_MSG_Alarm1_Time.set(temp_Msg), true);
But this does work (message is sent and loaded into Domoticz)
send(MySensors_MSG_Alarm1_Time.set("1.1"), true);
What am I not understanding?
I'm working on an alarm clock... my controller is Domotiocz. I'm using a text sensor to send the alarm time to my arduino.... the following post helped me get it all working properly -> lcd-clock-and-text-sensor-node-with-new-v_text
My clock also has buttons (like a traditional alarm clock), I've written all the code to change the alarm using the buttons.
Now I want to send the new alarm time set on the arduino to the controller (Domoticz), and have the text sensor updated. I thought this would simply be a send(....) command, but I can't get it working.
Here is a sub-set sample code of what I thought I needed to do to send the update (I'm on mysensors 2.0.*)
#define MY_DEBUG
#define MY_RADIO_NRF24
#define MY_NODE_ID 9
#include <SPI.h>
#include <MySensors.h>
#define cID_ALARM_TIME 1
MyMessage MySensors_MSG_Alarm1_Time(cID_ALARM_TIME, V_TEXT);
void setup() {
Serial.begin(115200);
request(cID_ALARM_TIME, V_TEXT);
}
void presentation() {
sendSketchInfo("WakeUp Clock", "0.0.1");
present(cID_ALARM_TIME, S_INFO, "Alarm Time", true);
}
void loop() {
int newHour = 12;
int newMinute = 45;
String val = String(newHour) + "." + String(newMinute);
send(MySensors_MSG_Alarm1_Time.set(val), true);
}
void receive(const MyMessage &message) {
if (message.type==V_TEXT) {
if (message.sensor == cID_ALARM_TIME){
// Here is where the return value comes from Domoticz when requesting the V_TEXT
}
}
}
When I run it I get the following console message....
35287 TSF:MSG:SEND,9-9-0-0,s=1,c=1,t=47,pt=1,l=1,sg=0,ft=0,st=OK:1
35297 TSF:MSG:READ,0-0-9,s=1,c=1,t=47,pt=1,l=1,sg=0:1
35302 TSF:MSG:ACK
and then my controller (Domoticz) updates the text sensor to the value of 1
I'm very confused, please help
UPDATE
I think it's a problem with the arduino board itself.
So since my previous posts I've tried multiple radios and I've got a 4 working nodes now:
Plus the Raspberry Pi 2 as gateway with NRF24L01+ PA/LNA is working.
So... it seems like it's a problem with that Uno board.... weird.
I've tried multiple radios (specifically ones that worked on the other boards) and none of them work. Like I said before, the board and the Rp2 seem to be communication but not properly.
Has anyone ran into a similar problem before?
Just tried a few more things...
./configure --my-gateway=serial --my-rf24-pa-level=RF24_PA_LOW --my-rf24-irq-pin=15
Other things I've tried....
Also, I'm using a fresh download of the mysensor libraries... from yesterday on both the Rp2 and my arduino
I think I've read every topic on this so far and I must have tried every combination.... and I'm stuck, so I'm hoping someone can see my mistake and help me get this sorted
Here is how I setup MySensors on my Raspberry Pi 2 - I followed the guide to install the NRF24L01+ PA/LNA radio with 4.7µ decoupling (and it previously worked on version 1.4 of mysensors)
Here is the contents of my mysGateway.cpp

So I'm totally confused by these messages... it seems like they are hearing each other but are having trouble communicating properly.
HELP!!!
@sundberg84 said:
Hard to say. St:fail generally means that you don't get ack from the receiver. This is normally range, power or hardware. There is not a general fix for this but you need to try and learn... i admit its strange I worked for some days. Maybe a radio fried ?
Don't have the radios to close to eachother. Try a.couple of meters.
Sorry I'm out of more solid ideas.
Hey sundberg84, quick question for you.
If you look at my debug logs above it looks like the gateway is infact receiving the message but the node thinks it fails. Con you confirm my interpretation of the following two lines?
NODE DEBUG
send: 42-42-0-0 s=1,c=1,t=0,pt=7,l=5,sg=0,st=fail:20.0
GATEWAY DEBUG
0;255;3;0;9;read: 42-42-0 s=1,c=1,t=0,pt=7,l=5,sg=0:20.0
If that's correct, could that change what the issue might be?

Thanks so much for all your suggestions so far.
I'll try the couple of meter thing tonight.
I've got a 10pk of radios and 1 long range one. I'll try combinations of all of them.
If those don't work then I'm stumped. I'll report back once I've tried those things
@sundberg84 I just can't figure out how a gateway and two nodes were working fine for days (plugged in the wall) and passing data every minute to my OpenHAB and the just instantly stop
@sundberg84 thanks for the tips.
I just got my "decoupling capacitor of 4.7uF" in the mail today, installed them, and nothing.
Other than that I've tried everything:
Here is what my current testbed looks like:
First I ran the following on both boards
#include <EEPROM.h>
void setup() {
// initialize the LED pin as an output.
pinMode(13, OUTPUT);
for (int i = 0 ; i < EEPROM.length() ; i++) {
EEPROM.write(i, 0);
}
// turn the LED on when we're done
digitalWrite(13, HIGH);
}
void loop() {
}
Then on the node board I ran the following
#define MY_CORE_ONLY
#include <MySensor.h>
#define NEW_NODE_ID 42 // Change 42 to the new node ID you want
void setup(){
Serial.begin(MY_BAUD_RATE);
Serial.print("Old node ID: ");
Serial.println(hwReadConfig(EEPROM_NODE_ID_ADDRESS));
Serial.println("Writing new ID");
hwWriteConfig(EEPROM_NODE_ID_ADDRESS, NEW_NODE_ID);
Serial.print("New node ID: ");
Serial.println(hwReadConfig(EEPROM_NODE_ID_ADDRESS));
}
void loop(){
}
Then I loaded the standard serialgateway code from the 2.0 dev branch which I downloaded yesterday
#define MY_DEBUG
#define MY_RADIO_NRF24
#define MY_RF24_PA_LEVEL RF24_PA_LOW
#define MY_GATEWAY_SERIAL
#define MY_LEDS_BLINKING_FEATURE
#define MY_DEFAULT_LED_BLINK_PERIOD 300
#define MY_INCLUSION_MODE_FEATURE
#define MY_INCLUSION_BUTTON_FEATURE
#define MY_INCLUSION_MODE_DURATION 60
#define MY_INCLUSION_MODE_BUTTON_PIN 3
#include <SPI.h>
#include <MySensor.h>
void setup() {
}
void presentation() {
}
void loop() {
}
Then I loaded this test script onto the node
#define MY_DEBUG
#define MY_RADIO_NRF24
#include <SPI.h>
#include <MySensor.h>
#include <DHT.h>
#define CHILD_ID_TEMP 1
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
void setup(){
}
void presentation(){
sendSketchInfo("TEST - Fake Temp", "0.1");
present(CHILD_ID_TEMP, S_TEMP);
}
void loop(){
send(msgTemp.set(20, 1));
delay(500);
}
and here is my result

I'm stumped
Is there anything else that could be causing it, or that I could try.
I doubt this is relevant but the only thing that changed the evening that it broke was that I brought home a new iPhone.... I'm sure it's not relevant but thought I should mention it.
Also I just ran across this post http://forum.mysensors.org/topic/3608/issues-with-setting-up-my-arduino-nano-serialgateway and thing that it sounds very similar to my issue.
I'm using the dev branch, pulled last Friday
So I setup an GatewayW5100MQTTClient
#include <SPI.h>

and a node with a temp + hum

send(msgTemp.set(temperature, 1));
#ifdef MY_DEBUG

}

lastHum = humidity;
send(msgHum.set(humidity, 1));
#ifdef MY_DEBUG
Serial.print("H: ");
Serial.println(humidity);
#endif
}
}
}
Then I got my Raspberry Pi running with OpenHAB and Mosquitto.
Everything was working great for 2 days. Then around 10pm yesterday it just stopped. I didn't notice it until this afternoon
What I've tried so far
Now here is all I'm getting in the serial monitor of the gateway
0;255;3;0;9;Starting gateway (RNNGA-, 2.0.0-beta)

I'm completely stumped...
HELP!!!
VICTORY!!!!
Apparently I just needed to bang my head against the keyboard and randomly try combinations until it worked.
So to hopefully help other people I'll post how I got it to work.

So to summarize here are the key parts (I think):
I'm still not sure if the second and third line in the mqtt-eventbus.cfg is correct. I don't have MyMQTT anywhere else, so I think I may try different combinations to see what works.
@TheoL you are probably completely correct.
I don't actually plan on building it.... it was just an interesting thought exercise.
I just thought of another great motorcycle project.
Some sort of GPS tracking + tilt sensor + logging
So, I thought I finally had everything setup properly, but alas something is still not working.
Overview
Devices
Status
As you can see my Arduino side of things is working properly, here is a sample of the messages I receive on my Raspberry Pi when I type mosquitto_sub -v -t 'mygateway1-out/#'
mygateway1-out/2/1/1/0/0 19.8
mygateway1-out/2/0/1/0/1 21.2
I'm hoping someone can help me troubleshoot the following code snippets to figure out what's wrong, I'm pretty sure the issue in between OpenHAB 2 and Mosquitto.
So here goes.

Help
What am I doing wrong?
SUCCESS!!!!
My new card worked, and my RPi is up and running. Now I just need to install OpenHAB onto it
@alexsh1 said:
@micah I think you can get a Samsung Class 10 microSD card for like $10 or something. I would avoid using a noname card from eBay/Aliexpress. Saves a lot of time.
BTW - this is hardly RPi's fault, isn't it?
Your right, it isn't the RPi's fault, although would it kill them to just include an 8gb flash chip on the device
@mfalkvidd said:
I'm unfortunately at about the same level as you. I can compile stuff and do basic troubleshooting, but merging the dev branch with the gateway code is way out of my league.
There is no way you are at 3.275% knowledge like me... I've seen many of your posts on here and you are at least a 4.532%... lol.... no honestly I've liked your posts and you seem very knowledgeable. You've got to be at least a 84.5%
Any thoughts on making a version for the 2.0 dev branch?
I recently switched my in-progress builds to 2.0 and am in the process of "trying" to get my Raspberry Pi2 setup with OpenHab and Mosquito. And the idea of not having to have an ethernet gateway arduino in the mix is appealing to me.
I would do it myself but I probably only have 3.275% of the required knowledge at this point
@korttoma thanks, but ouch, $37 CAD seems expensive, since I already have real smoke detectors in the house, and since I'm planning 3 of these devices that would be over $110
I was really hoping the answer would have been something like this MQ-9 
@the1laz well I have now learned my lesson
I just picked this up from Best Buy at lunch. Hopefully it'll fix the problem tonight
I've read most of the fabulous and long thread on Air Quality Sensor here in the forum.
I had a question, and I didn't post it in that thread because I didn't want to de-rail the flow, which seemed to focus a lot on calibration, examples and fabulous technical detail.
Use Case
I'm planning on making a combination device that sits on the nightstand and performs all the following:
Since I'll have wall power for this device I figured it would be really smart to add a Carbon Monoxide and Smoke sensor capabilities, since I'm planning on making one for each of my kids two bedrooms.
So I've got a simple question, which sensor should I buy?
I'd like something relatively economical, so not this SainSmart MH-Z14 Infrared Carbon Dioxide Sensor For Arduino... lol
So should I be looking at a MQ-2, MQ-3, MQ-4, MQ-5, MQ-6, MQ-7, MQ-8, MQ-9, MQ-131, MQ-135, MQ-136, MQ-137, MQ-138, MQ-214, MQ-216, MQ-303a, MQ-306a, MQ-307a, MQ-309a, MG811, AQ-104, AQ-2, AQ-3, AQ-7.... as you can see there are lots of choices.
I think I know the right answer already, but I'd love to hear the wisdom of the much more advanced crowd here at MySensors
3... 2... 1... go!

...and I do not want to be distracted while on the bike.
I completely agree. When I first got my bike 3 years ago I was shocked by how little information the dash provided, there wasn't even a clock!!!
But now I love that fact, I love riding around having no idea of the time, since when I'm on my bike I'm never in a rush and the journey is the reward
@dakipro said:
With mysensors I could have motorcycle "online" when it is in the garage, and once it becomes offline, domoticz will check if my phone is still at home and notify my wife. If she is with me on motorcycle, then I can go back for phone, or if she is at home she can maybe contact someone that I am visiting or something (i need to figure this out a bit more :)).
When I was re-reading this part I actually had a different idea.
I park my bike in the backyard, since I'm terribly unfortunate and do not have a garage. I only have a Suzuki GS500F, so I'm not really worried about anyone stealing it, but....
Your solution could easily be turned into a "theft warning" system that communicates to your phone, since your bike shouldn't be leaving your house without you on it.

I was actually thinking on using arduino to notify my wife that I forgot the phone, and another one maybe that I forgot the key in the ignition (with the main lights on, but maybe buzzer can do this as well
I think I've figured out the perfect solution to your forgotten phone and keys problem... it comes with several benefits including:

lol... sorry, I couldn't resist a bit of humor this morning 
. In actual fact your forgotten phone solution does sound interesting
@the1laz so what you are saying is that the super cheap ones on AliExpress are not high quality real ones? 
lol
I guess that's the cost of getting cheap components directly from China.... every now and then one of them is crappy
@TRS-80 I used to have a nice high quality 16gb card in my cell phone, but I recently gave it to my son for his tablet that's what I get for being a caring father... lol
I tried a few more installs last night of versions 1.5 and 1.8 and 1.9 of noobs and they all failed with different issues, so I'm ready to admit that it's the card.... so I'm off to the store at lunch for a new one.
@Mike-Musskopf thanks for all the great tips... I'm sure I'll be coming back to this post all frustrated in a week or so once my batteries are dead
There is just so much to learn with this Arduino MySensors stuff... I'm loving it, but there is just so much!
@TheoL I don't know what the issue it yet.
I just tried another Noobs install which was supposedly successful, but then on the auto reboot I'm getting tons of ext4-fs errors until it stops loading.
Some online digging suggested it may be an issue with the 1.9 version of Noobs (which I doubt). So I'm downloading an older release and I'll try that first, before tossing the SD card and replacing it.
I'm dying up here in Canada waiting for the real spring to start so I can get my motorcycle out.
So in the meantime I've been dreaming about the cool arduino things I could do to my bike (although I'm way to busy to ever get around to it).
I know it's not MySensors related, but I found two really cool arduino + motorcycle projects and I though you guys might enjoy checking them out.

ERGGGGG!!!!!!!!!
I spent 5 hours last night trying to get my new Raspberry Pi 2 setup. I don't mean the fancy MySensors integration stuff, I mean literally 5 hours trying to install Raspian!!!!!!
At this point I'm leaning towards a somehow broken micro SD that I got from AliExpress. I'll probably head to the computer store to buy a new one and try again.
It's so frustrating to waste so much time on a part or the process that should have been easy.
I didn't really write this post for help, although that's always welcome, it was more just as a place to vent. When I try and explain this kind of stuff to my friends their eyes just glaze over and they have no idea what I'm talking about.... I think I need to find some new friends who are technologically competent 
Thanks for listening to my complaining, I feel better already
@TheoL The nano is only temporary while I wait for AliExpress to deliver my 6 Pro Minis I ordered last week.... so hopefully the AAs will last 4 to 5 weeks... lol
Thanks for the feedback Mike.
The PIR is a good idea, but I've converted my basement into an apartment and have a tenant, so I don't want to mess with his lights, I just want to know if he leaves them on all the time
Great tip on replacing the breadboard. Learning to solder is the next thing on my list.
I've also just placed a big order from AliExpress for more toys... lol... including some Arduino Pros.
This hobby is addicting and quickly spirals out of control... I initially only wanted to make 1 sensor, and now I've already got a list of 8 projects I want to make
Hi everyone.
Been wanting to implement some mysensors goodness for awhile now, and I finally got around to building the first node for my home automation project.
I'm learning as I go, so things aren't pretty yet.
Before I continue, I wanted to start by thanking everyone on here, I've learned so much by reading your posts.
This first node is called "BasementMonitor". It'll eventually be mounted to the wall under the stairs in the basement. It's purpose is to scan the following and report them to my (soon to be built) Raspberry Pi OpenHAB.
Since this is my first build it's not pretty... basically stuff hot glued into a tupperware container. I'll pretty it up once I'm done all my testing.
Here is my sketch so far. It's still pretty raw and I've got a bunch more things to implement, but it works
