@3nibble

Diode is bad.
You can shorting it.
But then you can power this Arduino only from USB or from +5V in the same time!!!
Not both !!! This can damage your USB port.

@Olaf-Jacobs said in Temperature serial sketch:

First I had 4x DS18B20 temperature sensors hooked up to gpio4 on the pi without the resistor, this worked fine for some time till this gave some issues

Can you write what issues.
Why you connect DS18B20s to RPi without resistor ?
Is it some experiment?

@Sixkillers
You can wake up every hour, but hold wifi modem off, increment "wake up counter" and go to deep sleep.
Running time between deep sleeps will be very short
And connect to wifi one per day for example.
And make some tweaks for wifi connection:
For inspiration from Step 6 here:

https://www.instructables.com/ESP8266-Pro-Tips/

And final tweak here:

https://www.bakke.online/index.php/2017/06/24/esp8266-wifi-power-reduction-avoiding-network-scan/

@openhardware-io
I think this is not too useful concept.
In circuit diagram, there is no connection GPIO16 to RESET - so no deep sleep mode.
It seems, your node only connect to server when water leaks.
But what after two years, you do not know if battery are still good and your detector alive.
Better way use deep sleep, after some number deep sleep cycles ( one per day? ),
connect to wifi and send battery voltage for example.
If this message is missed, your controller can send you battery replacement message.

wake up circuit

@fdlou147
Ethernet ( with POE ) is very very expensive way to connect your sensors.
Look for prices 24port switches with POE for example.
And 24 nodes is not enough....

Super...
You add software for relay, switch or new temperature sensor through FOTA...
And then go to your node, remove it and connect this devices to it in fact.
No, you really do not need FOTA for this.
But for repairing some bugs in your program yes.
Other case is for example node ID, mqtt topic, some calibrations, offsets, Domoticz sensor IDX etc.

@PedroHernandez
If you build sensor with ethernet connectivity, simply send your data to Domoticz via http call using Domoticz JSON API.

Domoticz globally or only with MySensors ?
My Domoticz is the same version like yours.
Temperatures from ESPeasy are with two decimals on Temperature sensors page, but on devices page only one decimal.
Exactly the opposite like you wrote.

https://github.com/MajenkoLibraries/ICSC

Examples are there too.

( MySensors uses this code for 485 transport layer too )

Or another very simple example:

https://circuitdigest.com/microcontroller-projects/rs485-serial-communication-between-arduino-uno-and-arduino-nano

I would simply endured.
Once clean clothes go away and they will go out of the house dirty, smelly or naked...
Then they empty basket sure.

@esfnl
You are completely wrong and mix different things together.
Firstly - you wrote RFXcom (with long range antena ) and then mention link to RFLink.
Both devices have got separete device in Domoticz:

Secondly - RFLink and RFXCom are for intergration most commercial sensors and transducers to 433MHz.
You do not need install MySensors gateway on RPI for use them.
Simply connect them and select in Domoticz devices with appropriate interface.
Then you will see all sensors in your surroundings.
Mostly your neighbors meteostantions, heatpumps etc.
Here is my RFLink sensors list after couple of hours - none from me, all neighbors.
And I live on village ....
No block of flats.
( It is twice as long as you see )

I do not know RFXCom, but RFLink can receive data from MySensors nodes.
According your link, I do not test it.
ONLY receive - so no AUTO ID for nodes, no answer for presentation etc.
If you want use MySensors, I suggest build separate USB gateway and connect it to Domoticz and select
"MySensors Gateway USB" in device list.
That all.
No "./configure" and all this.

@mfalkvidd
Look for ESP-NOW ...
But it is limited to max 20 nodes per one network.
( Without encryption. With encryption, number of nodes is more limited - 6 or 10 )

Simplify your code maximally.
Remove PIR and UNO and connect D3 and D7 to correct levels.
Remove SoftwareSerial and all SMS function.
Only check serial debug messages for 4-5 hours run.
If it will work, then little by little add other functions.
My tip is problem with combination HW serial and SoftwareSerial.

https://www.pjrc.com/teensy/td_libs_AltSoftSerial.html

@abt
Look at LowPowerLab RFM69 examples.
In gateway sketch you can see how to handle incoming messages, in others how to send messages.
Combine this two and you obtain node, which is able to send messages to any node and receive messages too.
But it is not realy "mesh" , it is normal "peer to peer" network.
RFM69 has got good range, so in normal house real mesh is not needed, I think.
What I consider real mesh is MySensors with parent nodes or ESP-MESH:

https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/mesh.html

@user2684
Try:
Install ESPTOOL

run command ( it is for Linux - use com with its number in Windows )

esptool.py --port /dev/ttyUSB0 flash_id

Sonnof must response with its chip ID

Something like this:

Connecting...
Manufacturer: e0
Device: 4016

If it does, chip and connection is ok....

@kvn298
Each sensor must have unique child ID.
Your presentation:
DS18B20 ID=0 to max number of DS18B20
Relay ID=1
So second DS have got the same ID like relay.

@boozz
I am not user "roadman", but I am using MySensors and ESP8266 ( Wemos) so hopefully I can answer some of your questions.

I am using only one wifi access point (AP or router) in my home without problems.
But you can use one AP for your computers and TV and etc. and other for your sensors.
AP hw is cheap....

My house is 8x12 meters and wifi AP is in 2nd floor about in center of house.
It covers the entire house and very close ( 3m )out of house.
Near this wifi AP is RFM69 MySensors gateway, which covers up to the edge of my property 60 meters away.
( may further )

MySensors is goot for nodes a far away in my garden and for nodes with low energy consumption and fast reaction when wake up.
When MySensors node is sleeping and then wake up, it immediately continues in program flow immediately from the place of "sleep" command.
Wemos, when sleeping an wake ups, reboots and must connect to AP, which takes 8s to 2s when we do some tweakings.

But Wemos is very user friendly.
You can use some "ready use" solutions like ESPeasy or Tasmota and configure your node trough its web page.
Configure means select which sensor connect to which pin, send value to which contrtoller etc.

Write some programs or scripts:

All without the need to compile a new program.

And you can send to your controller what you want, not just what is implemented in MySensors.
( Using JSON API in my case with Domoticz )
And your controller can send anything to your node.

And for "MESH" topology.

Arduino "painlessMesh" library for ESPs exists.
But I think it is more easier to use more AP units - they are cheap ....

Domoticz has a nice dummy counter or dummy incremental counter, where you can enter the unit quantity.

MySensors unfortunately is unable to send data to these counters.
I am using them with ESP8266 to send energy consumption of my floor heating or number of actions of my relays.
So I recommend to use DzVents scripts in Domoticz instead of node-red.
I see two ways.
1.
Send from node for example in watts or m3 or litters.
With DzVents translate this value to time in minutes in Domoticz created dummy counter.

Write DzVents script for your switch, which saves time for ON action and when OFF action occurs, calculate time interval and adds minutes to dummy counter.

Then you can see the beautiful statistics for each day of the entire year back and the actual total value too.

For example here for my relay actions:
( "zapnuti" = "relay on" )

@chanky

It is 6 bytes sliding window which is filled from end and compared for correct byte order.
Here is _header loaded with data:

_header[5] = inch

Maybe this helps:

https://github.com/MajenkoLibraries/ICSC

@jurimetrics
Yes, good battery life time, but not good response time.
You open the door and receive message about it after couple of seconds.
With Arduino and rfm69 or NRF24 it is much better.

@chanky said in HM-TRP Gateway:

HM-TRP transceiver

Look at "MyTransportRS485.cpp and try adapt for your module which has serial communication too.
Initialize your module in "bool transportInit(void)" ?

And etc.

A lot of work .....

With battery powered sleeping wifi device will be always delay after door switch sensor action and message sending.
Find AP, connect to it etc.
Couple od seconds.
Maybe good for alarm, but not for switch light.

https://www.google.com/url?sa=t&source=web&rct=j&url=https://forum.mysensors.org/topic/1194/tutorial-openhab-with-serial-gateway&ved=2ahUKEwjjk9PFo67lAhUMxqYKHawADaIQrAIoADAAegQIBhAU&usg=AOvVaw0bbbvzi3M2OSTnta4tJOiJ&cshid=1571692845110

So I think you do not need mysgw on RPi. I do not use openHAB, but Domoticz, but it must be similar.
Load serial gateway sketch to Arduino with radio module, connect this Arduino to USB port of your RPi and select serial gateway in openHAB.

I do not understood your setup.
I see ttyUSB0, but your gateway runs on RPi - so nothing connected in USB.
I suppose radio module connected directly to your RPi. Or if your radio is connected to Arduino, load serial gateway sketch to that Arduino, not in RPi.

Your NRF is 2.4GHz. Your Wemos and home WiFi network is 2.4GHz too.
Maybe your WiFi router randomly switch wifi channels to the chanel of your NRF network.
Try set fixed channel on your router.

ENC28J60 for a stable gateway is not a good idea.
Buy some Wiznet...

I see in your code that you use:

#define MY_NODE_ID AUTO

Many users here have got a problem with the automatic allocation node ID with MySensors RS485 transmission protocol.
They must use manual ID allocation.
It really works for you?
Maybe the new versions of MySensors has this feature working.
It will be good news for me and others.

@pierrot10
And what about using normal soil moisture sensor and replace its pcb electrodes with something tougher.
Stainless steel nail knocked into wall or drill hole and put carbon rod from disassembled AA battery into it.
And experiment with electrode distance.

@dany17
If you want to use arduino connected via usb to computer and your sensors connected to that arduino with MySensors, I recommend starting with sketch "GatewaySerialRS485" from MySensors examples and present your sensors in this sketch.
But honestly, I don't think you have enough experience for this task yet.
For example:

byte value = analogRead(0);
 if (value == LOW){
  delay(10); 
  digitalWrite(gate, LOW);
 digitalWrite(relay1, LOW);
 delay(2000); 
 digitalWrite(gate, HIGH);
  } 
  
  if (value == HIGH){
  delay(10);
  digitalWrite(gate, LOW);
 digitalWrite(relay1, HIGH);
  delay(2000); 
  digitalWrite(gate, HIGH);

You compare analog readed value if it matches the exact value?
In how many cases does this occur?
And you know the value of the definition values LOW and HIGH in Arduino?

But if you move ( or sold ) your gateway to different network, what seems as reason for selecting SSID and password,
you still need recompile your code due to different IP of your controller.

@mrhutchinsonmn
openenergymonitor.org

Some Sonoff switching devices has got power metering.
Upload ESPeasy or Tasmota firmware and connect with HA....

#define MY_RFM69_ENABLE_ENCRYPTION

All nodes and gateway must have this enabled, and all must be personalized with the same AES key.
You need a helper-sketch specifically for this purpose

And why you do not remove a half of plastic cover above rotating sensor wheel to put sensor closer?

@koewacko
You can set negative offset 86kWh in Domoticz counter setup.

I am not sure with RST to GND.

Look here:

@zboblamont said in What did you build today (Pictures) ?:

umbillicals

It is rubber hoses with metal braiding.
But rubber degrades and this equipment is the most common cause of water leakage.

I think very useful device.
Stainless screw like detectors - no corrosion.
And all the time this device sits in dry area - no corrosion.
But software must call controller ( with battery level for example ) sometimes, say one per a day, to inform it is alive.
And if controller does not receive this message - sends alert.
I am using this for all my nodes - very easy in Domoticz.
If node dies, Domoticz send me e-mail ( and SMS ) with information.

And 40 years with this hoses for example ?

Try it .....

https://github.com/Arnold-n/P1P2Serial

@tiana
Forever sleeping door sensor with low battery?

"when last massage is send the node will never power the radio module"

Why door sensor, if it never sends message?

@tiana
And for what will be that offline node usefull?

@tiana
Create dummy contact sensor on your node and if node sends last message, it will trigger this contact before "die".
So controller knows, that it was last message and node is off.
But better is allow controller do its job, like wrote all others.
I personally check battery level and "no incoming messages in supposed interval" to send alert to my e-mail ( and SMS ).
In this example tank level sensors sends every 10min, so after 3 messages lost, I will be informed.

@eme
I am not sure if Domoticz can know, what you want.
I am not MySensors expert, but there are some weird things in your code:

#define CHILD_ID 0

MyMessage msgNEPA(0, V_STATUS);
MyMessage msg(CHILD_ID, V_STATUS);

msg and msgNEPA are identical, but you use it in different ways ....

MyMessage msgTank1(1, V_VOLUME);

For CHILD ID 1 type of message V_VOLUME, but in loop:

for (int sensor=1, pin=RELAY_PIN; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
// Register all sensors to gw (they will be created as child devices)
    present(sensor, S_BINARY);
    pinMode(pin, OUTPUT); // Then set relay pins in output mode  
    savedState = loadState(pin); // Set relay to last known state (using eeprom storage)
    digitalWrite(pin, savedState?RELAY_ON:RELAY_OFF);
    DEBUG_PRINT(F("Presented Relay st : "));
    DEBUG_PRINTLN(F(pin));
    send(msg.set(savedState? 0 : 1));
  }

You present CHILID ID 1 like S_BINARY

And then you set to this binary sensor volume value:

send(msgTank1.set(tank_level("liters")));

And in the same presentation loop you send value only to child id 0, because msg.set send to ID 0

@dce
Development ?

@mslv129jdg

mosquitto -v #start in verbose mode

If your mosquito is already running, you cannot start it again.

First stop it:

sudo service mosquitto stop
sudo systemctl stop mosquitto.service

And then try your:

mosquitto -v 

@mslv129jdg said in No working window appaers after start.:

Error: Address already in use

I do not use Mosquito, but maybe it is already running automatically after RPI starts?

@pihome
said in ds18b20 on 2xAAA battery:

i wanted to ask what others are doing and how they are managing voltage for voltage hungry sensors

One useful "switch" you have got on your PRO MINI.
My from ebay has got LDO marked LG33, which is MIC5219 LDO with shutdown pin capability.
So remove one from arduino hacked for ultra low consumption and use it for switch power hungry sensors.

Or only unsolder and bend up from pcb output and shutdown pin of LDO.
Then you can use 3AAA to power directly VCC ( 4.5V ). Connect this to RAW pin ( input LDO ) too.
Your sensors connect to unsoldered LDO output pin and shutdown pin connect with some output IO to drive your sensors ON/OFF.
Problem can be, that sensors run on 3.3V and your Arduino runs on 4.5V.
So you can put some diodes in series between battery and Vcc pin. Each diode ( not LED ) drops about 0.6V ( try different diodes ).
Another interesting idea with this LDO can be seen here:

https://forum.arduino.cc/index.php?topic=360996.15

@stevanov
It seems, that both of you use MySensors in "outofbox" state.
You do not write which radio module are using.
If RFM69 - change netwotk ID, with NRF24 change channel or network ID
Somewhere in config files.

MyConfig.h

#define MY_RF24_CHANNEL (76)
/**
 * @def MY_RF24_BASE_RADIO_ID
 * @brief RF24 radio network identifier.
 *
 * This acts as base value for sensor nodeId addresses. Change this (or channel) if you have more
 * than one sensor network.
 */
#ifndef MY_RF24_BASE_RADIO_ID
#define MY_RF24_BASE_RADIO_ID 0x00,0xFC,0xE1,0xA8,0xA8
#endif

/**
 * @def MY_RFM69_NETWORKID
 * @brief RFM69 Network ID. Use the same for all nodes that will talk to each other.
 */
#ifndef MY_RFM69_NETWORKID
#define MY_RFM69_NETWORKID (100)
#endif

Of course you must reprogram all nodes and gateway :o(

Or talk with your neighbours and ask them using different network ID if they only starting building their network and have got smaller number of sensors.

@pihome
very power hungry (Quiescent current 13uA) ?
And do you know, that with AAA (1000 mAh) it is 8 years in standby?
Maybe self discharge is greater.
Alternetively use 3xAAA with low quiescent current 3.3V LDO.

Sorry, but if you have got ethernet on each node, why using MS gateway? Simple use pure MQTT and publish to the broker. You only need MQTT library, not all MySensors in this case.

I do not know openhab, but in Domoticz this info ( battery and radio level ) I can see only in all devices list tab. Not like special sensor.

@bgunnarb
But readVcc returns long

long readVcc() {
  long result;
  // Read 1.1V reference against AVcc
  ADMUX = _BV(REFS0) | _BV(MUX3) | _BV(MUX2) | _BV(MUX1);
  delay(2); // Wait for Vref to settle
  ADCSRA |= _BV(ADSC); // Convert
  while (bit_is_set(ADCSRA,ADSC));
  result = ADCL;
  result |= ADCH<<8;
  result = 1126400L / result; // Back-calculate AVcc in mV
  return result;
}```

My way for monitoring battery.
Usually I have not got precise resistor with tolerance +-0.5% etc. for correct calculation, so I build resistor divider with what I approximately found.
Load my device with simple sketch, which reads data from ADC and write this raw ADC data to serial port.
I make notice, that for example 1009 corresponds to 6041mV with fresh battery measured with multimeter.
In my final sketch then using "magic" map Arduino function:

int raw_volt = analogRead(A1);

int volt = map(raw_volt, 0, 1009, 0, 6041);

Not very useful for "mass production", but for my prototyping it is ok.

@bjacobse said in Nano minimum voltage:

Datasheet: The device operates between 1.8-5.5 volts.
and this means to bypass/remove the voltage regulator on the Nano board

But it do NOT means with 16Mhz crystal on Arduino Nano ...

Why "plus" 7805.
Nano has got voltage regulator on board.
Original Arduinos 7805 I think, clones LM1117 usually.

Sorry, but you select most difficult way for build your sensor network.
You spare one arduino like serial gateway or one Wemos like ethernet wifi gateway and two years hacking RPI gateway with no result.
And you choose bad radio module too, I think. Instead of NRF24 use RFM69 and no more problems with distance in your home and mesh network function no needed.
For all beginners I recommended step by step solution of problems, if something do not works.
For example, first try simple communication between two modules using basic examples from RFM69 library for example.
If it works, you have got certainty, that your hardware is OK ( radio properly connected to arduino ).
Then you can load sketches for gateway and normal node to both modules and I bet, it will work.

I think it is not very difficult sharing radio between two Arduinos.
But only for sending ...
Simply hold CS signal off for both Arduinos.
And connect both of them by signal, which tell each other if it is sending.
Other Arduino must wait for indication, that radio is free.
And radio initialisation only from one of them too.

 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the WiFi link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * VERA CONFIGURATION:
 * Enter "ip-number:port" in the ip-field of the Arduino GW device. This will temporarily override any serial configuration for the Vera plugin.
 * E.g. If you want to use the defualt values in this sketch enter: 192.168.178.66:5003
 *
 * LED purposes:
 * - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs in your sketch, only the LEDs that is defined is used.
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *

Do not forgot, that some radios ( RFM69 ) allow only 255 address in one network.
No way connect more nodes to all receiving all messages ...

I am using HC-SR04 for reading water level too.
My measuring range is 110 cm = empty tank, 2 cm = full tank. ( this is now ).

Only problem I have got - when it is raining, some water drops condenses on sensor at night and sensor sends zero value.
Or I need better cover for my sensor ...
I eliminate by Domoticz code these bad readings.

I send to Domoticz actual distance and battery voltage every 10 minutes and calculate volume in m3 and percentage and water influx or consumption.

I am using battery powered Arduino Mini with MySensors network.
Only power led removed - consumption in sleep 70microA.
I am cutting off power for SR04 during sleep with small relay too and then it power on again.
There is a little delay before distance measuring and I read three times distance and use only last reading, because independently on delay time, first readings returns zero value sometimes after power on sr04...

Another problem is, that I power SR04 directly from battery, which voltage changes a little according ambient temperature.
Using voltage stabilizer for SR04 will be necessarily.
It was very quick project ...

@tommas
And what about setting it in BIOS of your PC?
It is normal function for PC.

It depends on type of your radio module too. With 868Mhz modules you can transmit for example only 1 percent of time per hour. ( In our country )
So if you send every minute, your transmit time can be max 0.6 sec.

@fernando-alvarez-buylla
I think you only need define your gateway in Domoticz.
That Is all.

@encrypt
I am not sure, if we speak about the same AES key.
I mean encryption key for RFM69 chip, because you select using encryption by this radio in your network.
But I am on my mobile only, so it is dificult study source codes Now.

@encrypt
I do not see encryption kye for RFM69 in your code...

When you switch off power for servos, they will stay in last position. And they have got a gear so not too easy self moving like single steppers.
And pan tilt kits are very cheap.

@alowhum
For me top user friendly is ESPeasy.
Through web interface selecting which sensors on which pins connected and to which controller send data.
When user become more experienced, he can use rules to write some "programs".
No recompilation needed.
But not useful for battery powered nodes which needs receive some data.

And what kit with stepper motors? Or you mean servo motors ?

You realy think, that it Is useful fór connecting two male connectors together, what way asked?

@terence-faul
comment step by step blocks of code for DOOR switch and try when it start to work.

If you plan using ESP chips or Raspberry as your sensors node, I think better way is ESPeasy or similar sw for ESPs.

How do you solve a situation where a SSR breakdown occurs and you are hunderts km away from home?
I think some classic relay is necessary in this application to handle error conditions.
Similarly, measuring the temperature in the blast near SSR is not very accurate.

https://www.letscontrolit.com/forum/viewtopic.php?f=2&t=6540

Piezo detector exists for detecting the impact of the drop.

It is a very interesting board for RS485 applications (modbus etc.).
But not quite right for Mysensors serial bus. RS485 is not designed for multimaster bus.
CAN bus drivers are most preferable.

You are probably the exception that you have electricity, gas and water gauges side by side and you can read them with one device.

@dbemowsk
Yes, sometimes it got USB1 instead of USB0.
You can create fix symlink for your USBtoSerial adapter and then write for example ttySonoff and allways will be right.

@fernando-alvarez-buylla
ESP with Tasmota or ESPeasy is good solution for sensors where power is available. But if you must use battery, you must find something different. And then MySensors with RFM69 radio (not your 2.4GHz NRF24L01 ) can be good choice. It has a lot of better distance on 848 or 433MHz.

@hyperflemme
Use gateway sketch and add sensor presentation and sensor data sending like in node sketch.

example from this forum:

void presentation() {
  // Present locally attached sensors here
    // Send the sketch version information to the gateway and Controller
  sendSketchInfo("AWI_ESP 120", "1.0");

  // Register all sensors to gw (they will be created as child devices)
  present(CHILD_ID, S_DIMMER, "AWI_ESP 120" " dimmer");
  present(CHILD_ID2, S_INFO, "AWI_ESP 120" " text");

}


void loop() {
  // Send locally attached sensors data here
 	send(msg.set(messageCounter)); 										// Send message to gw 
	messageCounter = ++messageCounter % 100 ;							// wrap
	send(msg2.set("Hallo")); 											// Send message to gw 
	// Send update every SLEEP_TIME
	wait(SLEEP_TIME) ;
}

void receive(const MyMessage &message) {  								// messages from node or controller
	//char printBuf[40] ;
	//Serial.print(message.getInt());
		//sprintf(printBuf, "Message node: %d %d  OK\n", message.sender, message.getInt());
}
	//Serial.print(printBuf) ;
	//sprintf(printBuf, "Messages: %d Errors: %d\n", messageCounter, messageErrorCounter);
	//Serial.print(printBuf) ;

Search forum here, you are not alone with this solution.

@dbemowsk

You must install esptool:
https://diyprojects.io/esp-easy-flash-firmware-esptool-py-esp8266/
or
https://github.com/arendst/Sonoff-Tasmota/wiki/Esptool#esptool-executable-windows--linux

Attention, there are some dependencies...

Then normally go to folder where .bin file is placed and run command:

esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash 0x00000 ESP_Easy_v2.0-20180322_normal_ESP8285_1024.bin

or

python esptool.py .........................

not ./esptool.py

But I suggest first try :

esptool.py --port /dev/ttyUSB0 flash_id

To check if every is OK ( port, etc )

I think we still do not know the topology of your network and we use different terms.
For most of us a "sensor" is - temperature sensor, humidity sensor, pressure sensor, etc. These sensors are connected to Arduino, which we call the "node".
These node are connected through radio or RS485 to Arduino which works like gateway and send received messages from nodes to controller ( Rpi with Domoticz ).
Usually gateway have got no sensors and you can use pure gateway sketch from examples.
But you can connect sensors directly to gateway, but you must modify gateway sketch then.

• setup your sensors
• present your sensors
• send values form your sensors.

And of course NO SLEEP FUNCTION in sensor send code.

Places, where put it is marked by comments in gateway sketch:

void setup()
{
    // Setup locally attached sensors
}

void presentation()
{
    // Present locally attached sensors
}

void loop()
{
    // Send locally attached sensor data here
}

Usual topology:

I think your topology:

@dbemowsk
It is from here:
https://github.com/letscontrolit/ESPEasy/releases/tag/v2.0-20180322

I connect it like you wrote.

@paweld
And must you really use SoftwareSerial and not AltSoftSerial, which is default for MySensors RS485 link layer?
You do not need include SoftwareSerial in your sketch then.

@dbemowsk
I have 12 of these new and working without any problems.
There is a missing gpio14 pin, where I connected the DS18B20, but I used the RX pin instead.
PCB design is more solid to me - you can even see the power fuse.
ESPeasy flashing without problem using esptool.
My way to program new Sonoffs:

To check comunication:
esptool.py --port /dev/ttyUSB0 flash_id

Erase flash:
esptool.py --port /dev/ttyUSB0 erase_flash

Program ESPeasy bin:
esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash 0x00000 ESP_Easy_v2.0-20180322_normal_ESP8285_1024.bin

Look here:
https://www.letscontrolit.com/forum/viewtopic.php?f=4&t=6415&p=35265#p35265

A long time before I try serial gateway from MySensors example and it works without any modification.
My configuration:
Domoticz
Pro mini like serial gateway - hw serial to Domoticz, sw serial to another Pro mini with serial motion node example with serial sw from MySensors too.
But no RS485 drivers, only sw serial tx and rx pins cross wired.
And do not forgot assign node_id in your sketch.

Can you connect to Sonoffs web pages?
Or can you see its SSID if they are in AP mode?
My Sonoffs Basic is switched off four times per every day and works like charm.
No DHCP, fixed IP, Domoticz. It is the most stable part of my sensors network.
It Is not probable, that all of yours are bad.
It must je different problem.

@hyperflemme
Than in your second sketch ( with sensors )
define MY_GATEWAY_SERIAL
is missing.
This sketch works like normal node without this, not as gateway with sensors connected.

I am not using OpenHAB but Domoticz.
But I think, that RFLink or RFXCom will help you with OpenHAB top.

Create a global variable and set to 0.
In the interrupt handler subroutine, set it to 1.
Check its status in the main program to determine if an interruption has occurred.

if (my_global_variable == 1)
    my_global_variable = 0;
    {do this}   / Action if an interrupt has occurred
if (awkens from sleep)
{do that}```

RFLink to your controller plus 4 button RF senders from ebay.

Do you connect your sensor to the same mega2560 which works like serial gateway or are you using different mega2560 connected through radio to serial gateway mega2560?

@zboblamont
I'm sorry to let you know that you are using Atmega328p outside the manufacturer-guaranteed specifications.
My apology again
But your super "Whisper NODE AVR" with onboard booster is very nice, but this booster "boost" to 3,3V.
And 16Mhz is out of range for ATmega328p at 3.3V
It wants a lot of courage to sell such a product for boys from Wisen

Look at circuit diagram:
https://bitbucket.org/talk2/whisper-node-avr/src/bad0f4f997dc9bae952d9aafd13397e1015eb602/Documentation/Whisper_Node-AVR_0.3.pdf?at=master&fileviewer=file-view-default

I believe that it works in most cases, but there can be situations - noise, EMI, when a problem occurs for this reason.
Something like PRO-MINI with 8MHz is safer for me and I do not have problems with random events.

Arduino 3V at 16MHz is out of specification. You cannot be surprised by no standart behavior.

For low number of DS18B20 and if you have got enough free pins,
I suggest use separate Arduino pin for each DS18B20.
Then your code is absolute universal and you always know, which pin what measure.
Do not matter, which DS18B20 you use.
With your method, you must read each DS18B20 signature - hardcoded it, compile and flash.
When sensor needs replacement due to malfunction - whole process again.

@hard-shovel
But mesh is on other direction too - parallel with movement and sure not still at the same position and pure parallel.
So digital signal can be generated longer time than you expected.
