The code that you posted:
send(msg.set(value==HIGH ? 1 : 0))
Translates to this
If ”value” is HIGH (true) then send 1, if not send 0
It has nothing to do with PIN 0 or 1
The same goes for
digitalWrite(RELAY_PIN_1, loadState(CHILD_ID_RELAY1)?RELAY_ON:RELAY_OFF);
It translates to
On RELAY_PIN_1, if it’s state is 1 write HIGH to RELAY_PIN_1 else write LOW.
If you use serial in your sketch you can’t use PIN 0 or 1 as those pins are TX and RX.
I started out with NRF 2.4 MHz radios for my 8 nodes MySensors and Domoticz. As I also install WiFi networks for customers and have access to our equipment at work I did a measurement at home because I could not get a reliable network.
First measurement revealed that my DECT wireless phone occupied the same channel that was the default for the NRF radios. And that my neighbors run their WiFi occupying all other channels. Equipment used was Ekahau.
I tried to tweak the channels but no avail.
So, I bought new radios, RFM833, and that was the end of my troubles. For two year now my eight nodes have not skipped a beat. I measure temperature, humidity, light (lux), UV and radioactivity.
And all my WiFi at home is at 5GHz as the 2.4 was exhausted.
I have about 40 NRF radios in a box with no use for them.
@rodaman if you have bought real NRF modules you have been satisfied.
Or if you have bought RFM 433, 833 or 915 MHz radios you had been more that pleased.
Not MySensors fault.
Be aware that most of the cheap NRF boards from China are counterfeit. If you have those in an environment with a lot of WiFi you won’t get any range at all. And all “modifications” to improve range posted on YouTube are not any improvement.
You need to buy real NRF modules with external antenna.
Just my two cents.
I do, really easy to setup. I have decided to only show the temperatures and battery status when battery level is low.
@sundberg84 if you look at the schematic you have connected MySX pin 10 to D2, but according to the spec for the MySX 2.4 it should go to D4.
I have now checked the PCB, and you are right @JPM
Pin 6 of the flash chip is not connected at all. No wonder I could not get that to work. Strangely is that the schematic is OK.
Thanks for finding this, I will modify my boards to get them working.
I checked the schematic, and:
First mistake: Seems that the schematic is OK, the label for SCK (pin 6) is connected to physical pin 16 which is PCINT13 on the Arduino,
Second mistake: that is a bug, filter capacitor is not connected correctly.
Third mistake: That is also a bug, pin 7 and 3 should be connected to VCC
Now I am going to check the PCB, be back shortly,
I just checked my batch of Rev 10, random check of the batch checked out OK. I have 20 boards.
@dbemowsk the Flashforge Finder dont have a heatbed and only uses PLA. And if you dont clean the bed with IPA it will lift. I always print with brim just to be sure.
Just do a regular calibration. Just hand tight the knobs, no force needed. Then start the calibration. Slowly rotate the knob until it the printer beeps. When the calibration is done. Print one of these that fits the bed thingiverse calibration
Carefully check the result. You should have a consistent print. If not, twist the knob closest to where you need to move re-calibrate. Thin line, the bed need to be closer to the nozzle, thick line that curls, move the bed away.
Note, when turning the knobs, just move it 1/4th turn each time. And make a note wich knob, the direction (clock wise or counter clock wise).
To get more info, search on youtube for flash forge finder calibration, there are a lot of videos there.
I bought Buildtak that I replaced the bed with. I don’t use glue. I did print out a couple of calibration figures that I downloaded from Thingiverse. After a couple of re-calibrations and printing with the calibration figures I have not touched the calibration again.
However, when I printed the MySensors box from Thingiverse the corners still lifted.
That was when I found the suggestion to print with a rim.
Now my prints never lift.
I also clean the bed after each print with IPA.
Print with a rim. There is a tickbox for it.
Yes, and I am very pleased with it.
@ahmedhodhod did it work with the suggested links?
PLease, DON’T write to eeprom in the loop(), you will destroy the eeprom. The lifecycle for the eeprom is 100000 writes/read, after that it is destroyed.
info about eeprom writes at arduino
EDIT: With the current code (write to eeprom every second) the eeprom will be destroyed after aprox 69 days.
I don't know if it affecting your case, but according to the source code for the BH1750 library you need to set the mode:
Source code for bh1750 library
Note that the begin() function needs a mode parameter, and that is used in configure, it if is not provided it is an invalid mode,
void BH1750::begin(uint8_t mode) {
Wire.begin();
//write8(mode);
configure(mode);
}
void BH1750::configure(uint8_t mode) {
switch (mode) {
case BH1750_CONTINUOUS_HIGH_RES_MODE:
case BH1750_CONTINUOUS_HIGH_RES_MODE_2:
case BH1750_CONTINUOUS_LOW_RES_MODE:
case BH1750_ONE_TIME_HIGH_RES_MODE:
case BH1750_ONE_TIME_HIGH_RES_MODE_2:
case BH1750_ONE_TIME_LOW_RES_MODE:
// apply a valid mode change
write8(mode);
_delay_ms(10);
break;
default:
// Invalid measurement mode
#if BH1750_DEBUG == 1
Serial.println("Invalid measurement mode");
#endif
break;
}
}```@pepson said in RFM69 new driver delay:
And tell me how you have connected Gateway to RPI3? By ethernet or by serial ? Because i see in your building Gateway that you dont use parameter ETHERNET on port 5003
I use Ethernet to connect to my Domoticz.
The reason that you don't see my configuration for ETHERNET or PORT is because they are default when you configure.
If you look at the file Makefile.inc you will see the build options. In my case the file looks like this:
SOC=BCM2837
CPPFLAGS=-march=armv8-a+crc -mtune=cortex-a53 -mfpu=neon-fp-armv8 -mfloat-abi=hard -DMY_RADIO_RFM69 -DMY_RFM69_NEW_DRIVER -DMY_GATEWAY_LINUX -DMY_DEBUG -DLINUX_SPI_BCM -DLINUX_ARCH_RASPBERRYPI -DMY_RFM69_FREQUENCY=RFM69_868MHZ -DMY_IS_RFM69HW

PREFIX=/usr/local
CC=gcc
CXX=g++
BUILDDIR=build
BINDIR=bin
GATEWAY_DIR=/usr/local/bin

So in my case I have these defines:
MY_RADIO_RFM69

MY_GATEWAY_LINUX
MY_DEBUG
LINUX_SPI_BCM
LINUX_ARCH_RASPBERRYPI
MY_RFM69_FREQUENCY=RFM69_868MHZ
MY_IS_RFM69HW
This is my generic temperature/humidity/battery level sketch that I use. I have upgraded all my nodes and gateway to 2.3.0 yesterday and I don't have any issue whatsoever

You only need repeater fi you have a node far away that can’t reach the gateway, then you add repeater on a node nearer the gateway.
See here: MySensors Network
And if the node has repeater defined it must allways have power and no Sleep.
Sorry, I can’t test the sketch.
You don't ned to change bootloader, I do because I run on battery and it fits my need.
I can't test your sketch as I don't have the necessary hardware to test it.
How far apart are your nodes?
My antenna is from AliExpress
OK,
Here goes what I have:
Arduino Pro Mini, chinese clones. Regulator and led removed. Soldered on EasyPCB rev 9.
Radio is RFM69 868 MHz with helicoil antenna on the nodes, 86 mm antenna on the Gateway
Bootloader is from https://github.com/MCUdude/MiniCore
The bootloader settings are:
Board: ATmega328
Bootloader: Yes
Variant: 328P / 328PA
BOD: 1.8v
Clock: 1MHz internal
Compiler LTO: Disabled (default)
On the EasyPCB I have only soldered the radio, the antenna and the Arduino. No booster, no capacitors, no resistors.
I have put a link on the REG and run the node on two AA batteries.
The nodes only have one sensor, the BME280.
The controller I use is Domoticz, latest version (I think).
I have now reprogrammed some of the nodes to 2.30 and I use NEW_DRIVER.
Gateway - 2.3.0
Patio - 2.3.0
Test-node - 2.3.0
Kitchen - 2.3.0
Bedroom - 2.3.0
UV and LUX - 2.3.0
No problems at all.
However, I do not use the receive() function on my nodes.
And I see that you use the REPEATER setting, if your node can reach the gateway the disable repeater.
I just checked all my nodes:
My nodes are within 40 meters from the gateway.
I will no reprogram the node 4 and 5 to use the new driver to see if that makes any difference.
Node 1 and 2 are the nodes farthest away from the gateway, there is one brick wall and three wood walls between the node and the gateway.
Just a hunch, add 4 mm to it so that it is 86 mm instead..
And the power supply for the RPi must be able to provide at leat 1.5 A at 5Volt. Dont go for a cheap powersupply, it wont cope with the power drain from the ROi.
What kind of antenna do you have on the RPi for the radio? And what kind of antenna do you have on the node?

Type as above and check the last entries, my RPi is revision a02082

@pepson
Yes, I run gateway 2.30 and nodes on 2.20 without new driver. No probems.
I run mysgw 2.30 on a RPi 3 Model B and all nodes on 2.20 with RFM69:
cat /proc/cpuinfo

Hardware : BCM2835
Revision : a02082
I did a git pull then configured:
./configure --my-transport=rfm69 --my-is-rfm69hw --my-rfm69-frequency=868
make
sudo make install
Note that I don't use LED's or specify gateway. My Controller is Domoticz
I then started the gateway with debug (note missing -d) (and the log is from today):

sudo systemctl start mysgw.service
System has been running without any hickup since then.

Date: Fri Mar 23 07:00:34 2018 -0300
Linux: Use config file for gateway settings (#1061)
- The following settings can be use on the config file:
- verbose=[debug,info,notice,warn,err] - Logging verbosity.
- log_file[0|1] - Enable logging to a file.
- log_filepath=(FILE) - Log file path.
- log_pipe=[0|1] - Enable logging to a named pipe(aka fifo).
Use this option to view your gateway's log messages from the
log_pipe_file (defined below).
To do so, run the following command on another terminal:
- $ cat "log_pipe_file"
- log_pipe_file=(FILE)
- syslog=[0|1] - Enable logging to syslog.
- eeprom_file=[/etc/mysensors.eeprom]
- eeprom_size=[1024]
- Change some mysgw parameters:
- Added:
- -q, --quiet: for quiet mode, disable log messages written to the
terminal.
- Removed:
- -d, --debug: removed, log messages are now enabled by default.
- Replaced:
- -b, --background: replaced by --daemon
- isatty() is no longer used, log messages by default are printed to
stderr unless the gateway is started with --quiet (#1022)
- MY_LINUX_CONFIG_FILE: no longer holds the path to the eeprom file,
but to the configuration file
My nodes has these definitions (I don't use New Driver):
#define MY_SPLASH_SCREEN_DISABLED
// Enable and select radio type attached
#define MY_RADIO_RFM69
#define MY_IS_RFM69HW
#define MY_RFM69_FREQUENCY RFM69_868MHZ
Still no rev 6 on itead or pcbway for rfm69 version 
@sundberg84
OK, good news. I will check it tomorrow and hopefully order a batch (or two).
@sundberg84 the RFM69 is soldered 180 degrees wrong on the new board 
@sundberg84 thanks for the offer, I can wait for the final, no worries. Do you have a list of the new components added on the back?
@sundberg84 how is the rev10 progress going? I am about to order a batch of EasyPCB but want the new bells and whistles
It look like the RFM69W version.
See the different versions here: RFM69-versions
Test if this reduces your memory consumption.
This is what I have added
Disable the splash screen with:
#define MY_SPLASH_SCREEN_DISABLED // This saves a couple of bytes
Then for every serial.print I have embedded those with #ifdef MY_DEBUG/#endif
There is no need to serial print when running in silent mode.
I have also embedded the missing serial.print with the F("string") function.
This saves memory by storing strings in flash instead of memory.
I could not get the code to compile as I don't have the proper DHT library.

No, it is shorting pin 1 and 3 on the DS1820
Remove the yellow wire behind the DS1820, you are shorting it.
Yes, you can use the pictures. If you need better pictues I can provide it to you.
I have just finished soldering my last four easypcb with BME280:
This area that I have painted red.
Proposal.
Make two of the pads at the extra area with A4 and A5 (I2C) as more and more sensors are I2C.
Preferably the two pads next to VCC and GND.
Like the BMP280 and BME280, they are I2C with VCC, GND, SCL and SDA, so first line of pins in the extra area should be:
VCC o-o-o-o
GND o-o-o-o
A5 -o o o o
A4 -o o o o
The new layout with the SMD on the bottom layer looks good.
Please make the pad for the antenna on the "bottom" larger, same as "above". Most ready-made antennas are with a 90 degree wire for easier soldering.
@sundberg84 I have now a node running with the BAT link removed, the REG link attached and I have used the Arduino_Vcc library.
The battery report are consistent with the battery voltage measured with a digital volt meter.
EDIT: Code below had a bug in it, I have fixed the bug and updated the code. The bug affected the temperature readings
So, to run the RFM69 board on two AA batteries I have done the following:
/**

@sundberg84 said in 
Easy/Newbie PCB for MySensors:
Why dont you use the internal library to measure the battery voltage? Im thinking about this and can't find a reason to move the voltage divider since without the booster you could just use the internalref and a library to measure the voltage?
Good point, I have not thought of that. I will test it it. And will probably save some uA in the process. Thanks,
If I don’t use the booster and connect both BAT and REG and feed the board with two AA batteries i can use the battery components to measure the voltage of the battery. That is how I use it today.
Now that I think of it, there is a small difference between the NRF and RFM board, the prototype area on the RFM board is not correctly spaced, the holes are a fraction to narrow spaced, one cant fit a header there without bending the pins
Put the battery measurement components under the Arduino. This makes the board more generic and frees up space on the right side of the board that can be used for more sensors. Expand the prototype area so that more sensors can be installed on the board.
And if one uses the board for battery only, the whole right section can be cut off but the battery measurement circuit is still there.

Hi,
I have this function in my sketch:
void CheckRSSI()
{
char SendingRSSI[10];
char ReceivingRSSI[10];
char TxPowerLevel[10];
char TxPowerPercent[10];
String sendRSSI;
itoa(RFM69_getSendingRSSI(), SendingRSSI,10);
wait(200);
itoa(RFM69_getReceivingRSSI(), ReceivingRSSI,10);
wait(200);
itoa(RFM69_getTxPowerLevel(), TxPowerLevel,10);
wait(200);
itoa(RFM69_getTxPowerPercent(), TxPowerPercent,10);
wait(200);
// Now, combine all values and send it in
// Line should look like "T:-90 R:-81 PL:20 PP:100"
sendRSSI = "T: ";
sendRSSI.concat(SendingRSSI);
sendRSSI.concat(" R:");
sendRSSI.concat(ReceivingRSSI);
sendRSSI.concat(" PL:");
sendRSSI.concat(TxPowerLevel);
sendRSSI.concat(" PP:");
sendRSSI.concat(TxPowerPercent);
#ifdef MY_DEBUG
Serial.print(F("RSSI String: "));
Serial.println(sendRSSI);
#endif
send(msgRSSI.set(sendRSSI));
}
The output is:
RSSI String: T: -59 R:-51 PL:-2 PP:0
TSF:MSG:SEND,13-13-0-0,s=1,c=1,t=47,pt=0,l=23,sg=0,ft=0,st=1
Why does send() only send 1 instead of the string?
Using 2.2.0-rc.1
I am using this:
// Bosch BME280 Embedded Adventures MOD-1022 weather multi-sensor Arduino code,
// written originally by Embedded Adventures.
// https://github.com/embeddedadventures/BME280
#include <BME280_MOD-1022.h>```Change
lecture_adc = BAR_SENSOR_ANALOG_PIN;
To
lecture_adc = analogRead(BAR_SENSOR_ANALOG_PIN);
Just add:
BME280.writeMode(smSleep); // go to sleep, save battery
After your have read the bme280, just before you call sleep().
How is the pulse counter set up? Is it connected to the S0 port?
Edit:
If you are using S0 it is vital that you use a pull down resistor, if you dont’t have that you get false pulses.
Same error here.

Replacing
printf("bcm2835_delayMicroseconds %" PRIu64 "\n", micros);
with
printf("bcm2835_delayMicroseconds %lld\n", micros);
in file drivers/BCM/bcm2835.c fixed the issue.
EDIT:
It did compile, but it segfaults when I try to start mysgw
Time to get a fresh copy from git
EDIT2:
Fix from commit in bug report fixed it.
git clone https://github.com/mysensors/MySensors.git --branch development
./configure
make
sudo make install
sudo /usr/local/bin/mysgw -d
This is how I did it on a Raspberry Pi 3.
You have run ./configure twice, run it like this:
./configure --my-transport=nrf24 --my-gateway=ethernet --my-port=5003
One thing that I have found quite frustrating is that when I develop some new feature or add a sensor to my MySensors-network I always forget to clear the eeprom and then I need to reprogram the arduino with /mysensors/MySensors/examples/ClearEepromConfig/ClearEepromConfig.ino
Then I have to reprogram the code again and do my testing.
Could you add a new function to the core code that has a function like:
MySensorsClearEEprom()
{
#ifdef MYDEBUG
Serial.println("Started clearing. Please wait...");
#endif
for (uint16_t i=0; i<EEPROM_LOCAL_CONFIG_ADDRESS; i++) {
hwWriteConfig(i,0xFF);
}
#ifdef MYDEBUG
Serial.println("Clearing done.");
#endif
}
I then can i my code while testing add this function in setup()
#define PORT_CLEAR_EEPROM 6
pinMode(PORT_CLEAR_EEPROM,INPUT);
digitalWrite(PORT_CLEAR_EEPROM,HIGH);
if(digitalRead(PORT_CLEAR_EEPROM) == LOW) {
MySensorsClearEEprom()
}
If I set (in this case) port 6 to ground, the eeprom is cleared.
I went for the BME280, a little expensive, but it uses I2C and can be run from 1.71 volt to 3.3 volt.
@ronnyandre you need to uninstall those libraries and install those mentioned in the heading: Installing the dependencies: NodeManager
There are two errors:
The serious one:
void setup()
{
dht.setup(DHT_DATA_PIN); // set data pin of DHT sensor
if (UPDATE_INTERVAL <= dht.getMinimumSamplingPeriod()) {
Serial.println("Warning: UPDATE_INTERVAL is smaller than supported by the sensor!");
/*---MQ2---------------------------------------------------------*/
Ro = MQCalibration(MQ_SENSOR_ANALOG_PIN); //Calibrating the sensor. Please make sure the sensor is in clean air
}
// Sleep for the time of the minimum sampling period to give the sensor time to power up
// (otherwise, timeout errors might occure for the first reading)
sleep(dht.getMinimumSamplingPeriod());
}
If you look at where you have put your initializing code you will realize that the code is never run unless you make the UPDATE_INTERVAL so small that it is less than dht.getMinimumSamplingPeriod
Change the setup() to this instead:
void setup()
{
dht.setup(DHT_DATA_PIN); // set data pin of DHT sensor
if (UPDATE_INTERVAL <= dht.getMinimumSamplingPeriod()) {
Serial.println("Warning: UPDATE_INTERVAL is smaller than supported by the sensor!");
}
// Sleep for the time of the minimum sampling period to give the sensor time to power up
// (otherwise, timeout errors might occure for the first reading)
sleep(dht.getMinimumSamplingPeriod());
/*---MQ2---------------------------------------------------------*/
Ro = MQCalibration(MQ_SENSOR_ANALOG_PIN); //Calibrating the sensor. Please make sure the sensor is in clean air
}
The second one is this:
sendSketchInfo("TemperatureAndHumidity", "1.1");
sendSketchInfo("Air Quality Sensor", "1.0"); /*MQ2*/
You should only have one entry:
sendSketchInfo("Temperature, Humidity and Gas", "1.1");
Allright, now it looks like I am getting them 
PCBs have been finished and are ready to be sent out.
Here is a code example that works for me. I have an energy meter with S0 output and I use Domoticz as the controller.
/**
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

* REVISION HISTORY
* Version 1.0 - Henrik EKblad
* Version 1.1 - Mikael Carlsson
*
* DESCRIPTION
* This sketch provides an example how to implement a sensor reading from an energy meter
* Use this sensor to measure KWH and Watt of your house meeter
* You need to set the correct pulsefactor of your meeter (blinks per KWH).
* The sensor starts by fetching current KWH value from gateway.
* Reports both KWH and Watt back to gateway.
*
* Unfortunately millis() won't increment when the Arduino is in
* sleepmode. So we cannot make this sensor sleep if we also want
* to calculate/report watt-number.

}```OK, I think I have nailed it. I am now running a beta code pulling S0 from my energy meter and I am getting consistent results.
Before when I checked the domoticz.db I got this for Energy:
sqlite> select Name, sValue from DeviceStatus;
Storage kWh|0.000;4773.700
Now I get this:
sqlite> select Name, sValue from DeviceStatus;
Storage kWh|118.000;11678062.000
Notice that the first field is now with value, previously it was 0.000 (and I have updated the meter count to the actual value)
And in table Meter I now get consistent results:
sqlite> SELECT Value, Usage, Date FROM Meter WHERE DeviceRowID=43;
11678003|1170|2017-07-22 09:25:00
11678012|1170|2017-07-22 09:30:00
11678021|1180|2017-07-22 09:35:00
11678031|1180|2017-07-22 09:40:00
11678043|1170|2017-07-22 09:45:00
11678053|1180|2017-07-22 09:50:00
11678062|1180|2017-07-22 09:55:00
11678072|1180|2017-07-22 10:00:00
The field Usage is now populated as it should.
I will let the code run for a couple of days, then I will post the updated code here.
This happened to me too, I ordered from the link, and thought I was Ok with the order. Yesterday I did find out that my order was waiting for the gerber files, so I downloaded, zipped and uploaded the to itead. I also mailed them about it. Got a reply that they should check the gerber files.
EDIT:
This was not the case, I am still debugging the issue, in the mean time I have deleted the code.
After some debugging it seems that Domoticz messes with the V_WATT and V_KWH, and the solution is to have two sensors, one for kWh and one for W.
After I changed it, I have consistent W and kWh.
