So @Greg-Bowers .... you found the flaw?

hello @jkandasa
..... a little parenthesis!
( what's new in MyC )

https://github.com/mycontroller-org/server/releases/tag/development

I searched on the forum how to use ID255 but found nothing practical

https://forum.mysensors.org/topic/8941/mysensors-get-temperature-value-from-another-node-through-the-gateway?_=1684325843882&lang=fr

https://github.com/mysensors/MySensors/blob/development/examples/PingPongSensor/PingPongSensor.ino

how to find a communication problem on a channel?
the solution is to check each link.

on the gateway : https://www.mysensors.org/build/advanced_gateway

add leds or a single one to visualize the dialog # Radio Traffic LEDs
(this function can also be used on a node )

on the gateway a dummy/virtual value can be created to simulate a probe (the result will tell us if the gateway is not at fault

additional information may not be useful

Hello

what type of architecture do you use ?

(an example)
bus....... = Nodes <--- ? ---> Gateway <--- Usb ---> Controller
material = Atmega ..............arduinoUno.................Raspy4
software = MyS2.3.............MyS2.3 ....................Ubuntu/MyC2.x

?= RF RFM RS

"harmonic disturbance" https://www.electronics-tutorials.ws/accircuits/harmonics.html
(wired or wireless )

yes a problem more and more frequent with the saturation of the hertzian frequencies

which controller you use ? : https://www.mysensors.org/controller

congratulations for having found the solution

have a language translation problem or a bad formulation of me.

my question was what kind of gateway you used, but yes your solution is good.

but the solution that is "the linux terminal of raspi" to read the Logs is the best.

In my case my controller puts the logs in /opt/apps/mycontroller, reading the file gives useful information, but of course it's better with the options enabled in the gateway
#define MY_DEBUG
// #define MY_SPECIAL_DEBUG //maybe also ? (see the utility?)

Hello

"I changed my wireles gateway (Wemos-D1 Mini) to serial. "... yes but what is it?
Arduino Usb Gateway?

reading the log files can be useful, their location is different depending on the system.

some info :
https://www.mysensors.org/build/debug
https://www.mysensors.org/build/parser

no info, nothing found

https://github.com/mysensors/MySensors/search?q=MY_CORE_ONLY

thanks for the feedback

I don't think adding a timer function in "MyTransport.cpp" is a good thing,
Serial Gateway has many hours of flight and many people use it, there are many possible causes to your problem.

• a saturated herztian atmosphere
• the RF module
• the structure of the scketch
  -....
  have a lower flow and can be useful?
  #define MY_RF24_DATARATE (RF24_250KBPS)
  #define MY_RF24_PA_LEVEL (RF24_PA_HIGH)

but thanks for this solution you give, it can be useful for others.

Your question raises many problems, but a simple solution may be possible

In the creation of a home automation system there are two basic philosophies.

• a centralized "intelligence" that contains the parameters and algorithms to give orders/actions to the Nodes
• or a distributed "intelligence", each Node with its own algorithm receives the list of things to do.

for your problem how to have a "degraded mode" in case of scratch.

Hello to you

MY_TRANSPORT_WAIT_READY_MS

"MY_TRANSPORT_WAIT_READY_MS. Very useful. You can tell a node to try connecting to the gateway for X seconds, but if it fails, it should just carry on. I usually set this to 10000 so that it will try connecting to the network for ten seconds, and then just continue starting the node. The default is 0, meaning that if a node can't connect to the gateway it will never reach the loop() portion of your code!" API 2.0

thanks for the feedback.

can we say that with cheap material (no-name) we pay the rest of the bill later?
(what was the model??)

look here https://www.home-assistant.io/integrations/mysensors#custom-unit-of-measurement
the "CUSTOM UNIT OF MEASUREMENT" part

tests with type V_LEVEL or V_UNIT_PREFIX

if it works the problem comes from the version of MySensors Arduino library ?
Library API

tries to create a virtual value, a false sensor.

"It worked for about 6 months" ... wear and tear or a case of a component ???

courage you will find

( it is difficult to help a person on a material problem without seeing anything )

Yes, this is a good idea.

but not with an ethernet switch/hub, only an ethernet crossover cable.

yes also here (France) there is still some person with the mask, a remnant of the trauma?

the role of the mask was to gag us.

a virus is not stopped by a piece of paper on the face, it's in the air, it settles everywhere.
The only solution was to go out naked and take a shower when we got home.

@monte said in Boards esp8266 v3.1.0 or Newer Doesn't Work with MySensors:

il existe tellement de solutions bon marché et faciles pour ce que font mysensors

as rich in possibilities as this does not exist

a line of the examples given in the sketches for the use of RS485 can be a source of problem
(it's my case, I use Pin2 or3 for a long time )

...
// Define this to enables DE-pin management on defined pin
#define MY_RS485_DE_PIN 2
(2 or 3 is an interrupt pin for a Uno)

nice realization, clean and modern

on my Gateway GUI I have the function ( différente suivant la librairie )

oled.ssd1306WriteCmd(SSD1306_DISPLAYOFF); // set the OLED display to OFF

No MyS is not dead, we are La!

give us the result! Ask on the HA/Hassio forum for a solution?

you are in mode #define MY_NODE_ID "static" for the nodes??

hello
yes the title of the post is not clear (I did not find another one)
it means, how to regulate the sending of messages on the Controller/Gateway.

History:
In test for the reading of the Electric consumption, I found many sketches and some with MySensors.
Here is the one of restraint: texte du lien

The Problem and a burst of dialogue from the Messages, too much dialogue.

On the sketch there is a line with : SEND_FREQUENCY_FULL
but it doesn't work, nothing in the *.cpp and *.h files either
I think that when a Library passes from hands to hands, some elements are deleted in part.

Question :
how to delay the sending of the values ?

which choice ?
. a [ SendTime = currentTime - previousMillis ] well placed in the program ? (it didn't work )
. planting [Wait(time)] (nothing grows)
. use Echo received and delay the send ? Echo receive
. contact Henry Walton Jones Jr. to learn more about the origin of the library?
(I don't have his number, and he's getting too old)

Hello
CAN Bus is still functional, and no problem.

a question : is it possible to implement the use of 2 CAN Module on the same Gateway.
2 CAN bus or RS485 + CAN

as for the RS485 in example for a Mega2560 board

MyConfig.h
......
 * Example: @code #define MY_RS485_HWSERIAL Serial1 @endcode
 */
//#define MY_RS485_HWSERIAL (Serial1)

maybe this can be useful : https://forum.mysensors.org/topic/6948/synchronising-light-switch

I use it with version 1requestState or 2 requestTime() on some sketches
(I modified the structure, moved some parts to functions to make it more readable )

here can be the beginning of an answer:
https://forum.mysensors.org/topic/812/realtimeclockdisplaysensor-ino-no-fetch-time-from-controller

"I don't know where to start," ... in a chain there are
links, see which one is at fault

"defective" since the migration from serial to mqtt" ...? what does it mean?

I dialogue with you, but without really knowing, just to create a chain reaction of ideas

maybe others have an idea !??

Translated with www.DeepL.com/Translator (free version)

Hello

can you tell us more about your mysensors architecture.
see the chain of elements, hardware and software.

your message is about : Mqtt 'mosquitto? - OpenHab - Arduino" uno?"

hello

did you find some time to add the CAN bus error feedback?

the 2 and 3 is good, enough

and give me the procedure for the sketch

sorry for the alert.

it was an error in the gateway sketch

a ... #define MY_WITH_LEDS_BLINKING_INVERSE... duplicate, is misplaced

désolé

go to a fourth node
(Gw0 - Nodes 55 56 57 58 )

.. bip bip

"Are my ideas good" .. yes yes c'est tout bon

"It will not flash the diodes in case of communication problems" ... it's not a problem, Christmas is still far

But yes a counter that increments is a good thing.

what do you want me to test ????

bool transportSanityCheck(void)
{
	return (CAN0.getError()==CAN_OK)
}

The "radio guy" opinion would be great.
((I'll look for possible help ). )

Re-Edit

hal/transport/CAN/MyTransportCAN.cpp

bool transportSanityCheck(void)
{
	// not implemented yet
	return true;
}

Edit
I searched the web, and using SNR RSSI with the CAN bus is a dead end.
https://www.thethingsnetwork.org/docs/lorawan/rssi-and-snr/

The original idea was: how to check the status of the CAN bus.

. is there any dialogue ?
. are there any messages?

of course this can be done with MySensors.

But to get as close as possible to the communication channel (the CAN bus) I thought it was easy to do.

this is by reading the post of bricoleau here
text french
that the idea came to me.

• on the arduino have a blinking led to say that the CAN bus is out of order (but we forget, it loads the program unnecessarily)

and also because you suggested it to me
yes we have to beat the iron when it is hot, and my time available for the computer will soon be reduced (purchase and work of a house)

I appreciate very much your explanatory note, thank you

I activated the 16Mhz in the sketch, and put it back in the library

  #define MY_NODE_ID 57          /*Node en ID static*/

  #define MY_CAN
  #define CAN_CLOCK MCP_16MHZ

Thank you for this clarification.
(yes translator and my neuron it gives crooked dialog)

"If I have missed a relevant property, please let me know."

The list of #define go up for the MySensors sketch .
( if I'm not mistaken ?)

***for MCP_CAN_lib **************** MyConfig.h line 280 to 315
CAN_INT // Pin for interrupting an incoming message.
CAN_CS // Chip selection pin.
CAN_SPEED // Transmission speed. The allowed values can be found in mcp_can_dfs.h
CAN_CLOCK // Can clock. Allowed values can be found in mcp_can_dfs.h.
CAN_BUF_SIZE // Assembly buffer size. As long messages can be split and arrive mixed with other messages, an assembly buffer is needed.

can be added, for testing and controlling the CAN bus

#define CAN_MSGAVAIL    
#define CAN_OK  
#define CAN_CTRLERROR  

Thanks

return of the last 24 hours .
CAN bus no error, good dialogue, no hole in the measurements and commands.

the hardware base on the bus is :
gateway + node 55 + node 56 .

I will add another node 57.
I think to go until 6 nodes

I just did the test, switch to 16Mhz in the file MyConfig.h

it works well, I have no error

#define CAN_CLOCK MCP_16MHZ

I didn't think it was possible, is it incompatible?
overwritten the values of the file MyConfig.h

thank you for the information

" I would suggest doing a long term test to see if it is stable." yes I will stress it to see the weakness

".. If it is stable, try to use it in real use cases." yes that's the point

One last question

I'm going from 8Mhz to 16Mhz (in development/MyConfig.h on line 306)

question: can you explain how I can bring up in the sketch the parameters that are related to the MCP_CAN_lib library

it should not be complicated for me it is only text to insert ???

an example with the #define CAN_CLOCK MCP_8MHZ

Thanks Adam Slowik

http://learntohackit.com/intro/# it can be useful information ???

Gateway Logs on MyController
(CAN Bus and RS485 Bus)

two separate files
CAN log
RS485 log

files split in parts :
A : gateways startup
B : reboot of the gateways
C : launch of MyClock Nodes (id23 and id55)
D ; periodic refresh requestTime(receiveTime)
E ; send value (1700 and 2100)

(I have prepared the work for you to read)

a 1st analysis

• (at the bottom of the listing, the sending of values "1700 or 2100" with MyC)
  The RS485 bus dialogues much more, the CAN bus is more timid

Adam Slowik bravo

I test what now???
the ACK ??

Oh yes, I have to check the disconnection of the nodes.
The Gateway gives me the impression that the information does not go back to MyC if a Node is off ???

a test with DHT22 probes.

the values go up well on MyC
real decimal values

here is a screen shot

big vue

I have to find another type of probes, the DHT22 give me losses, or my sketch is to review

ReEdit
error
I got excited too fast
the values are not refreshed.
I look better

ReRe-edition
I made a mistake, as I play a little too much with MyController, I add and remove gateways from nodes and other salads.
and well in the end it makes no sense

I cleaned up the Yaml files of MyC and it's better

#define MY_DEBUG_VERBOSE_CAN .....yes yes I already tested it, it's very good.
(a very useful function)

..go to

• Reloading the CAN-MyS update
• ClearEeprom of the GW and Nodes
• Reloading of Sketches on GW and Nodes

Bravo

• sendSketchInfo(" text ...."); and well up

• requestTime(receiveTime); and functional

Ahhhhhh Lovely this is great
I offer the coffee crossing

(what was the problem ??? )

After the test on the Digital I/O of the Nodes ,
now I test the Analog I/O

a Super Thank You @Adam-Slowik

what would you like as a novelty ???

" MySensors is dead ?" ... No, in my house it is still alive.

but it's true you are right to ask the question.
the programmers, the creators are always The ?????

I didn't modify anything (the other sketches work)

But I just looked at the quartz and it's 16M!! (SW-65-16M)

I am lost

https://www.gotronic.fr/art-module-bus-can-sbc-can01-28405.htm

but on the doc there is :
The 8000000 stands that the MCP2515 operates with a clock of 8 MHz. This
depends on the quartz used and may need to be adjusted.

error
on the official doc it's a 16Mhz like mine.

• https://www.joy-it.net/en/products/SBC-CAN01
  OSCILLATOR 16 MHz Crystal Oscillator

so 8Mhz or 16Mhz?
and why does it work with the previous sketches?

@Adam-Slowik "Could you post the CAN version here?"

it's the same, except that the bus is not rs485 but CAN

......
........
#define MY_NODE_ID 55          /*Node en ID static*/

  #define MY_CAN
  
  #include "SSD1306Ascii.h"
........
.....

but I'll go back to PaulStoffregen's Lib <TimeLib.h> to see if I can simplify the basic sketch of MySensors

I tested my sketch with clock and OLED to see

bah No the time is not up

I give this information for an overview, it can help for the continuation (but not to give you work )

The listing of the messages of mySensors

@Adam-Slowik "Can you push your patch to my repository? " .... I don't know how

On the CAN principle

@Adam-Slowik "Based on this id, the filters are configured to remove all messages not intended for the current node. This way, if the gateway wants to send a message to the node with id = 51, only the node with that id receives that message." ... yes, that's how I see it.

another way to say/explain it.

"The philosophy of CAN is to constitute a messaging system.
The messages (the letter) send on the CAN Bus (the post office), distributed by the CAN Bus (the letter carrier).

Each (letter) have each an identifier (stamp of the post ) that ... identifies it.
And put in the right mailbox (the MCP2515) according to the choice of filter/mask ( color, scent? ) of the letter."

So there are two "stratum" of dialogue / work.

• one on the Can Bus, and another on the Nodes.

The idea is to relieve the Nodes of unnecessary work/effort with the risks that this brings. Less letter to open

@Adam-Slowik "... my modules and arduinos are buried in a box in my attic..." ? Arduino 8bit and MySensors is over for you?
( if it's a personal / family reason don't say anything )

"Can you provide logs (gateway/node) from the reset scenario. It would be great to have these logs for RS485 and CAN so I can compare them."

listing

Released today 2 gateways connect to MyController

• UNO_usb - Gateway and RS485 bus
• UNO_usb - Gateway and CAN Bus

with connect, a UNO with the basic sketch "RelayWithButtonActuator_base.ino" (slightly modified)
with ... a Led and a Switch, for each bus.

The Listing split in several parts

"Log of the IDE and MyC for the two types of bus (node34 and node 54), CAN and RS485.

- Listing Action RESET with MyController 
	2 parts for CAN
	and 
	2 parts for RS485
	

and 

- Listing Action On/Off on the node switch or with MyController 
	4 parts for CAN
	and 
	4 parts for RS485

No error on the Reset, it works fine, an error from me.

Oh yes, I even found an error
the sendSketchInfo("test xxxxx", "1.0"); is not up

see the end of the video
video

....I will answer the other question tomorrow.

test with the digital output inputs of 2 Arduino on CAN Bus.

• status of a button and control of a led with MyC

a proof in video that it is functional

video

all is not functional, on the end of the video, the reset or reboot does not work, (but functional with the RS485 bus)
.... to follow
(now the Analog values, decimal to test )

I would like to test the Node to Node with the filtering.
a question : is it difficult to put the filters on the MySensors sketch ???

there are still MySensors on the forum ???
if yes, a help for Adam Slowik would be a great thing.
implement it in MyS Yes Yes

Thanks

a topo of the day

on the hardware side, I got screwed with an arduino pin that became too soft, too dilated, look for an hour before understanding why no dialog.

Otherwise, on the Gateway side, no problem, MyController recognized well.

and CAN_Switch.ino is good too, my Widget on MyC switches well on the switch change.

listing of the dialog pour le Node 51 (set up in a fixed place )

Hello

to save time, you can tell me more about the configuration of MCP_CAN_lib

not all settings are shown on the MyS sketch

here in an example https://github.com/coryjfowler/MCP_CAN_lib/blob/master/examples/CAN_receive/CAN_receive.ino
there are some parameters to adjust

or the filters https://github.com/coryjfowler/MCP_CAN_lib/blob/master/examples/Extended_MaskFilter/Extended_MaskFilter.ino

can you indicate me the files in question ???
(I think I have found but to confirm)

to make it clean

thanks

"you can choose a different library"
I like this freedom of choice, my questioning is not necessary

"I would really appreciate your comments"
yes yes in 4 to 5 days, theoretically

Finally a high reliability Wired Bus for MySensors with the MyS protocol which is extraordinarily rich.
(the RS485 bus is good, but the cables/wiring must be more rigorous and the management of collisions more delicate for X Nodes, and the CAN bus is a good field bus )

Hello
thank you for the answer

questions:

• which CAN library did you start on,
  mcp2515.h or mcp_can.h ...etc

• the management of Float values is also managed ?
  (numbers with decimals )
  like this library which manages Floats https://github.com/pierremolinaro/acan/search?q=float

• and of course any CAN card is managed, like this one https://www.gotronic.fr/ori-module-bus-can-sbc-can01-28405.jpg

I prepare another test computer for the installation of your version

Translated with www.DeepL.com/Translator (free version)

a request for information, how to do :

to add the CAN transport you have to modify the files or replace them with what exists ?

• MyTransportCAN.cpp
• MyTransportHAL.h
  https://github.com/mysensors/MySensors/pull/1488/commits/492aa631298d5960b4060f94084cdafaaad18f21

I will maybe test the work of AdamSlowik

good evening

again a new sketch for the "void receiveTime" function
(without RTC clock)

• start synchronization with the controller and regularly for the drift of the arduino.
• display time and date on an OLED screen
• error message when a loss of communication with the controller occurs

here is a small truth table for the state of the input/output and the values to give to MyController

pdf image

#define RELAY_ON 0        //  1 reversal of values
  #define RELAY_OFF 1    //  0 

now only the MyS states to be sent to MyC to find.

I stop my dialogue

Hello

a request for information.
What value should be given to avoid a difference in the on/off states between the visualization on the controller and the reality on the LEDs of the Expander module?

• on the Arduino's Mysensors sketch
• on the configuration of the Field of MyController

on which feet to start ????

Another question, how to have the synchronicity of the state of the physical outputs (relays/led) and the view on MyC ???

with this version of the sketch the state of the outputs is well to go back to the controller after reboot of the Node

void receive(const MyMessage &message) {
   if (message.getType()==V_STATUS) {
    // Change relay state
    state = (bool)message.getInt();
     PCF27a.write(4,  state?RELAY_ON:RELAY_OFF);
    send(msg4.set(state?RELAY_ON:RELAY_OFF))

but now with this version, the reality is false
(an augmented reality )

void receive(const MyMessage &message) {
  if (message.getType()==V_STATUS) {
    switch (message.sensor) {
      case 4:
            state = message.getBool();
            PCF27a.write(4,  state?RELAY_ON:RELAY_OFF);
      break;
      

the function

// send(msg4.set(PCF27a.read(4)));

is removed and you can't see how to add it

merci

Operation Expander success

I show you two sketches, still based on Rob Tillaart library.

• the 1st one is a basic version without MySensors
  (to understand how the library works)
  an Input (a shunt) controls an Output.
  4 inputs 4 outputs

• the 2nd one is with MySensors, everything goes up well on MyController, and the 1st time (I am surprised )

a request, a hand for the 2nd for a "clean" touch up of the code (or errors to remove ?? )
Yes code readable for beginners, simple function.

after cella another video

Thanks and good night

Hello

a little more information on the PCF8574 based material

obsolete industrial equipment recovered in a trash can.
system building controller from "Johnson Control" the "metasys" game
https://cgproducts.johnsoncontrols.com/MET_PDF/6364040.PDF

why the choice of this hardware base ?
The Opto coupler !

if not for the Arduino sketch, and its functionning with the PCF8574 library from RobT it's functional

as soon as I activate
#define MY_TRANSPORT_WAIT_READY_MS 3000
it works, why it works

Thank you jkandasa for your curiosity, yes the fact that I dive back into it there was like a spark inter neuronal

Thanks

well, here we are, we think we are alone in the world, but no

thank you skywatch

they is or my sketch that I answer to jkandasa

Hello jkandasa

I will have to find my skecth in my sketch box

but in the meantime I have a problem to solve, very serious

I can't connect to the MyController forum.
it happened after I cleared my browser cache

I have recreated a new password but nothing, I don't have the hands.

This sentence is thrown in my face:

Login failed
We cannot connect you, probably because your session has expired. Please try again.

even creating a new account is impossible

thank you

Hello

good news, the libraries for PCF8574 are not compatible with MySensors, one less thing to manage.

I have been testing for a week the different version of library found on the web, it works well, but when I insert the bases of the sketch for MySensors the i2C communication is blocked, and the PCF8574 remains the four iron in the air.

even with the super https://github.com/RobTillaart/PCF8574

I've been looking for a practical expander and MySensors on the web, but nothing.

So everything is normal???

yes it's not easy, the loss of package is a difficult thing to
to counter, but not entirely.
and the multiple layers of a computer system do not help

some philosophy on collision avoidance
https://arduino.stackexchange.com/questions/24523/rs485-multimaster-communication-with-collision-avoidance

don't mix the Protocol (data encapsulation)
and the physical support (voltage frequency impendance / star or serial bus)

the ModBus protocol on a RS485 support
https://www.electroniclinic.com/arduino-modbus-rs485-arduino-rs485-master-and-slave/

a different explanation https://www.codrey.com/learn/rs-485-arduino-quick-primer/

for information
https://github.com/sonyarouje/Arduino_HardwareSerial_RS485

But the best solution (reliability and especially lightness of the sketch) is the CAN bus

I may have said some stupid things

Translated with www.DeepL.com/Translator (free version)

Yes MySensors must continue, and it continues to live
it's a system open to all possible modifications.

an economical system, not obsolete in 1 years, not polluting Hertzian and reliable with the implementation of field bus (Rs485 - CAN)

why such a madness of technology to tell me that in my living room it is 20°C or that my front door is open?

a web server for a temperature sensor is nonsense.

Yes to the Minimalist System

Faithful reader of Elektor since the number 1, I see the technological progression
which leads us to our loss.

IoT objects on LoRaWan still a polluting thing*.

ByBye

• waste / health / freedom

Translated with www.DeepL.com/Translator (free version)

can be the good solution to put everything back to MyController

without doing anything

 bool info;

Void setup  {......
  //info send to gateway
   send(msg.set(info)); 
   send(msgx.set(info)); //pour d'autres  
...}

to be seen later

exit status 1 : 'value' was not declared in this scope

but why in the setup ?
you have to put it in Loop () ?

Hello jkandasa

I spent the day on the Mysensors website copying/translating some parts of the "serial_api_20" doc
(I have no more eyes )

yes I will add it soon
send(msg.set(value==HIGH ? 1 : 0)); // Relay

you mas understood, I try to write well the code of the sckech
so that MyCrontroller goes up cleanly the sensors

Merci
