Hello to you
"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
French version of mycontroller has just arrived 
https://forum.mycontroller.org/topic/68/french/12
version 2 continues its evolution, quietly but surely
MyController ? super light and super fast.
Yes errors on the commands given through domoticz
only one in three and taken into account
terminal copy serial

...and the local push button commands are not taken into account
in the loop something that dies its tail ??
// Inform controller if state change from input
if (debouncer.update())
{
bool newState = !digitalRead(CONTROL_INPUT_PIN);
if (newState != currentState)
{
currentState = newState;
if (currentState != controllerState)
{
send(msg.set(currentState));
}
}
}
merci Boum
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.
for your problem how to have a "degraded mode" in case of scratch.

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

Thank you for the link
I'll head in that direction
feedback after testing
Waiting
"Waiting using the Arduino delay() command is not a good idea. " ... https://www.mysensors.org/download/sensor_api_20
utili:
https://forum.mysensors.org/topic/10386/what-is-the-good-wait-time
https://forum.mysensors.org/topic/9099/does-gateway-loop-required-wait-or-delay
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.
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
good evening
again a new sketch for the "void receiveTime" function
(without RTC clock)

why open a new post, there is still some space here
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 )
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)
...
avoided interrupt pins.
the pin 10 is a good thing
