Hi, do you think it's possible to connect de Dallas sensor to pin 7, 8 and 9 of the arduino ?
Like this :
#define ONE_WIRE_BUS 8 // Pin where dallase sensor is connected
#define ONE_WIRE_GND 9
#define ONE_WIRE_VCC 7
I have tried, and the temperature is always 85°C ...
Hello @mrc-core
You can use the Vcc.h library, and mesure the voltage without any wire 
Hi guys !
I'm trying to convert a temperature sketch with CR2032 battery monitoring, and the OneWire without resistor lib (to avoid the 4.7k resistor attached to the Dallas)
But, it seems I have not well followed the instructions to convert a sketch from 1.5.4 to 2.0, because it won't compile !
Here is the original sketch (1.5) :
// avec mesure de la batterie avec Vcc.h
// ok avec pile CR2032 et docATmega328 8Mhz MYSBootloader et efuse 0x07
// pour DS18B20 SANS resistance

ok ! I will check the wires and signal output from the movement sensors
@gloob said:
What type of sensors are they? Do they act like simple "switches" or what kind of signal do they offer on the output?
For the door, I assume they are like reed switch (with magnet fixed on the door itself)
For the movement ... I don't know !
Hello,
In my house, I have an old alarm system installed, with :
All the sensors are wired, and all the cables are going un a closet, where the old alarm system is installed.
I don't want to use the old alarm because it is broken, but I want to reuse the sensors. I have electric power in the closet, so it will not be a batteries powered node, so is my idea realisable :
is it correct ?
Thanks a lot for your answer 
I must be an idiot but ... I can't compile your sketch ... Which version of MySensors lib are you using ? (I'm with 1.5.4)
Hello,
Is it possible to have 1.5.4 and 2.0 MySensors on the same computer ?
@sghazagh said:
@m26872 Thank you very much mate.
I just added the battery reporting part and it works like a charm.Many many thanks...
Did you add 1MOhm resistor between the Input pin and the reed switch ?
I didn't know it was possible !
So : Vcc and GND from the battery, and TX, RX and GND to my usb serial adapter ?
Hello !
I have sometimes tempertures nodes, powered by batteries, which are freezing ... If I reboot the node, all is working correctly ...
How can I debug it ? If I connect the node to my computer, it will change the power input, so if it's a power related issue, I will not see it ...
Do you have any idea ?
Thanks !
@fleinze said:
@carmelo42 sorry I somehow missed your post. I use the standard-bootloader as I did not get Optiboot to run on the 3.3V/8MHz pro minis. I set the extended fuse to 0x07 (BOD disabled) by editing boards.txt.
thanks !
is is a bit confusing for me :
I have some lifetime issues with my CR2032 sensor .. and I suspect the fuses are not correctly set ...
If you can light up my mind it will be perfect
@fleinze said:
@carmelo42
The no-resistor-library can be found here:
https://wp.josh.com/2014/06/23/no-external-pull-up-needed-for-ds18b20-temp-sensor/The resistors (there are two but the other one is barely visible) are for voltage-measurement. In a later version I got rid of them using this resistor-less method of measurement:
http://provideyourown.com/2012/secret-arduino-voltmeter-measure-battery-voltage/
great
Did you change the bootloader ? Which one did you use ?
@fleinze said:
@carmelo42 I just changed coin-cell on one of my sensors. It lasted since for 10 months, this is ok for me.
10 months ? it's perfect
Can you provide the modified version of the library to avoid using 4.7k resistor for the Dallas sensor ?
What is for the resistor on the pic ? for the voltage mesurement ?
what about your nodes after several months ?
@siod said:
@carmelo42 no, unfortunately I don´t have any logs, any idea how to create logs?
maybe if you keep your node connected to your computer with USB to serial adapter ?
@siod my temperature nodes work good, but my relay one doesn't work 
Do you have any logs when it freezes ?
@carmelo42 said:
@jeti said:
@carmelo42 yes
I have this serial/usb adapter :
https://img1.picload.org/image/ldrrddg/deekrobot-isp.pngCan you tell me how I connect it to my node ? (noob question I guess ... but I don't want to burn my node
)
I have found the answer myself with the schematic
Have you ever tried to power the node with 1 x CR2032 battery ?
I have tried, but the node doesn't send anything further than 5 meters ...
I have added the C5 capacitor (on the "My Slim 2AA node"), and replaced the nrf24 from my GW with a NRF24L01+PA+LNA.
It's way better
So far, no problem .. I will keep you updated in the following days
Anyway, thanks for your help 
yes, I have tried 15 meters away : same problem
I have cleaned the eeprom last night after your advice, and the node is currently at 50 centimeters from the GW. (I have also changed the power source for the node : I was using 1 x CR2032 battery, but last night I have used 2 brand new AA batteries)
On my Slim AA Node, I have not the C5 cap, I will add it ...
Can it be a bootoloader issue ? (I'm using my Atmega at 8 Mhz)
@sundberg84 thanks
All my nodes (and GW, pretty sure) have already decoupling capacitors ...
I'm using "standard" temperature sketch :

I have this serial/usb adapter :
https://img1.picload.org/image/ldrrddg/deekrobot-isp.png
Can you tell me how I connect it to my node ? (noob question I guess ... but I don't want to burn my node )
@m26872 is it possible to send the sketch in the atmega on board ? using an FTDI serial/usb ?
I'm using these relay : https://www.mysensors.org/build/relay
I think there is already protection from the coil voltage spikes.
thanks @m26872
I have ordered smd capacitors for c5 ... but I think it will be good
Can you explain the role of the C5 cap ? I know that C4 is for decoupling for the radio, but C1, C2, C3 and C4 : I don't know !
Another little question
with my brand new atmega328p, I have burned the bootloader with an arduino uno with the "ArduinoISP" in it.
After that, I have sent the sketch with another arduino (with it's own atmega removed) and my brand new atmega like that :
https://www.arduino.cc/en/uploads/Tutorial/ArduinoUSBSerialSimple.png
Is it possible to put the sketch in the atmega directly on the slim2aabatterynode board ? With an FTDI serial device ?
@Nuubi said:
These are most often related to noise of the power supply or other transient noise/spikes in the circuit (due to a relay for example).
To be more specific, I'd first remove the relay from the circuit and just use a led instead. If the node works then without problems for longer time, the reason indicates it's a noise issue from the relay section.
Similar examples can be found, e.g. http://forum.arduino.cc/index.php?topic=186879.15
Generally these are solved by separating the power supplies, or 'de-coupling'. A good read illustrating the situation, please read it through: http://www.thebox.myzen.co.uk/Tutorial/De-coupling.html
I have bunch of nodes that are troublesome. So fat it's been due to noisy somewhere in the circuit. Also, noticed that some nodes start to malfunction after few years due to low quality capacitors. And that is painful to cure...
thanks
I understand better
So, if I understand the right way, I have to put a decoupling capacitor because of the noise produced by the power supply and another decoupling capacitor because of the noise produced by the relay.
I have already a 47µF cap on the VCC and GND pins of my NRF24.
Should I put another 47µF beetween the VCC and GND of my relay ?
I think it's noob question ... may be it'll be nice to put these infos in the relay page of mysensors website ?
@jeti said:
ups... C5 is also not there on my board,it shoud be parallel to C4!
is your sensor working without C5 ?
I have received yesterday my little packet from DirtyPCB
11 PCBs, so 33 sensors
I'm just wondering where the C5 capactior will go on the board .. Can't figure out
Hello
In the BOM file there is C5 capacitor, but I can't figure out where it does stand on the board. Can you help please ?
@Yveaux said:
@carmelo42 Using foto-sensitive pcb material, UV light and printing your design on transparent slides it should also be possible.
I no longer bother creating PCB's myself, as I can order them very cheap from China, with silkscreen, solder mask and far better quality...
ok ! I have ordered PCBs from dirtypcb.com (the files for "my-slim-2aa-battery-node"), but I'm not advanced enough to design PCBs with siklscreen and solder mask (yet ^^)
With a USB microscope and tiny solder iron, it's ok to solder atmega328p-au !
Is it possible to do DIY PCB for SMD atmega ?
I'm doing my PCBs with toner transfer + acetone at the moment. It works great for DIP atmega, but I can't do SMD version because the ways are to tiny ...
Any idea ?

Thanks for your support by ordering. I actually recieved another 50+ share credit transfer from DirtyPCBs today. It'll be donated to MySensors right away.If you look at post 116 you'll see the I used a 10Mohm pull-up between Vcc and atmega input pin. Reed switch connects between Gnd and input pin.
Thanks to you for providing us theses files
Ok, my mistake (I juste received my 10 MOhm resistor
Perfect, I just have to wait now for the little yellow packet
@Nuubi said:
"Classic" way to rule out the power source + relay related issues is to replace the relay with a led.
Noise in power lines may stop the NRF module, but also Arduino can get messed up due to spikes in power supply.
I did'nt see your answer ...
What can I do to avoid this ? Put the relay away from the NRF & atmega ?
I have ordered the 2.0 boards, they are on their way to my home
I'm plannign to use them as :
For the door sensor, can you tell me if I'm good :
I have to use a 1MOhm resistor between the pin of atmega and one wire of the reed switch ? So I will have the longest battery life (my atmegas are burned at 1 Mhz or 8 Mhz)
Am I right ?
"try adding a decoupling capacitor of 4.7µ - 47µF (the exact size usually doesn't matter)"
I can use 4.7µ or 47µ only ? or a size between 4.7 and 47 ?
very cool
Will you provie PCB at dirtypcb.com ?
As soon as you do it I order PCB
I have 2 gateways : one with 1.5.4 and one with 2.0 :
I have tested with 2 temp nodes : one with 1.5.4 version and one with 2.0 : the 2 gateways can see the 2 nodes !
I finally have found the problem : I had only Vcc.h in my VCC folder ... So the .cpp file was misisng !!
--> noob alert
ok ....
it is not the 1st time I have problems with lib MYS lib install ... I have done this :
on a fresh linux install, DL the Arduino IDE 1.6.5, in the IDE menu, DL the MYS libraries and DallasSensors Temp lib ...
Is this the wrong way ?
I have installed lib 2.0 on my linux virtual machine. When I try to compile temperature node with battery monitoring here is what I got :

I understand there is a problem with Vcc and vcc float ... but ...
@scalz do you know if it's possible to have 1.5.4 and 2.0 in my Arduino IDE ?
Ok !
I will update all my sensors + gw to 2.0 and test it with my sensors (as long as the outside temperatures won't go below 15°C all day I don't need to have my boiler functionnal so I can do some tests
If it's ok I stay with 2.0, if not I can go back to 1.5.4
I'm using just temperature nodes, relay actuator nodes and distance nodes : so all the code is available on mysensors website with 2.0
I will try the v2.0 !
Juste flash my gateway with the new sketch ?
Can v1.5.4 nodes and v2.0 nodes work with 2.0 gateway ?
May be it's quite simply to upgrade to v2.0 and my freeze problems will be solved ...
@hek said:
Then you have to calculate the number of sleepcycles * sleep time to get the passed time.
In the links provided by @scalz, the max time for the watchdog is 8 seconds, and my node is asleep for 15 minutes !
@scalz said:
Hello.
you have to use a watchdog timer for this. You can use the internal wdt of you mini pro etc.. or use an external hardware wdt.
https://forum.mysensors.org/topic/4760/watchdog-on-2-0/17
https://tushev.org/articles/arduino/5/arduino-and-watchdog-timer
merci scalz
but if my node (temperature or door) goes to sleep : the watchdog will not be reseted and it will restart ?
hi !
is it possible to program a node restart every 24 hours ?
I have lots of nodes around my house, and sometimes one of them stops sending information ... After a restart it's ok, so I want to automatically restart my sensors to avoid manualy doing it.
is it possible ?
thanks !
@carmelo24 it's ok now
here is my sketch :
// Sketch pour commander un relai en mode impultionnel.
#include <MySensor.h>
#include <SPI.h>
#include <NewPing.h>
#define node_id 66
#define RELAY_1 3 // Arduino Digital I/O pin number for first relay (second on pin+1 etc)

unsigned long SLEEP_TIME = 500; // Sleep time between reads (in milliseconds)
MySensor gw;
NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.
MyMessage msg(CHILD_ID, V_DISTANCE);
boolean metric = true;
long temps;
void setup()
{
// Initialize library and add callback for incoming messages
gw.begin(incomingMessage, node_id, true);
// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("RelayDistance", "1.1");
// Fetch relay status
// Register all sensors to gw (they will be created as child devices)
gw.present(RELAY_1, S_LIGHT);
gw.present(CHILD_ID, S_DISTANCE);
boolean metric = gw.getConfig().isMetric;

}
void loop()
{
// Alway process incoming messages whenever possible
gw.process();
// mesure de la distance si ça fait plus de 10 secondes qu'on ne l'a pas fait
if((millis() - temps) > 10000) {
int dist = metric?sonar.ping_cm():sonar.ping_in();
gw.send(msg.set(dist));
Serial.print(dist);
Serial.print("toto");

}
}
void incomingMessage(const MyMessage &message) {
// action du relais (avec impulsion, pour action comme un bouton poussoir)
if (message.type==V_LIGHT) {

Could you share any details on "it doesn't work"?
The distance stays at 0 cm on my controller, and the relay actuator isn't triggered when I click it on my controller (I use my sensors with Jeedom)
Hello, I'm trying to aggregate 2 sketches : distance and relay actuator node ...
But I think I'm going the wrong way because it doesn't work ...

Can you see what's going wrong ?
thanls !
Hi, great project !
Can you detail how you burn the bootloader and the sketch into the atmega ? (I mean, how do you wire the pinout to upload bootloader and sketch)
Thanks !!
Hello,
I have a serial gateway, 2 mySensors temperature nodes, and 1 relay mySensors node.
The 2 temperature nodes work good, but the relay one stops worling after a few hours .. I have to turn it off and on again and it works again for a few hours ...
(I use mysensors with jeedom).
I have think the problem could be material, I have built another relay board, with another arduino (duemilanove original) and a new NRF ... but same again ...
Do you have some idea ?
Thanks
Carmelo
