Domoticz data timeout

gbuico

@kimot , sure, I know that tmr.now() is a NodeMCU function and I'm trying to use it in the "void loop()" sketch of my NodeMCU to send a "changed status" at regular interval.
Unfortunately I'm still getting compile errors as if the function has to be declared or requires an "include".
Back to your post above where you mention ESPEasy... I don't know this alternative, but from what I'm reading is just a sketch that you produce with a specific tool instead of using Arduino IDE software, so I cannot see how this can be better or easier compared to Mysensors since the "dumb side" seems to be in Domoticz.
Still since you know both, I'm sure that you have a good reason... so, may I ask you to spend a couple of words more to explain why you think this can make things simpler? Thanks a lot

@gbuico
tmr.now() is LUA function
NodeMCU LUA is firmware, which you load to your NodeMCU ( or other ESP2866 ) and then write your programs in LUA scripts, which stores in ESP2866.

MySensors is writen In Ardfuino language ( C++ ), so Arduino IDE compile your program and load it to ESP2866. And there is not tmr.now(). Use millis() instead off.

ESPeasy is firemware to load to ESP2866.
It runs on ESP2866 and you can create sensors and write simple "program" when connected to ESP webpage.
There are any timeouts, you can send message one per day or month, no problem.
You do not need compile ESPeasy itself. Use compiled file and download it to your ESP2866.

First you create your sensors in Domoticz as "Dummy" devices and remembers their "idx".
Then connect with browser to your sensor with ESPeasy running and through its webpage you can define different sensors ( sensor type, GPIO where connected, its domoticz idx , sending interval, etc )
For example, for DS18b20 you select pin for 1-wire bus, then you can see all sensors on this bus and select which you need. Temperature is automatically send to Domoticz.
Different sensor - no problem, select for example pins for i2c bus, discover this bus and then select sensor.
Display - select i2c address and it is done.
But what I really love on ESPeasy is its communication model.
If you cannot send some info through ESPeasy autmatically, you can write json command and send to Domotic whateverelse.
Need send data from Domoticz to your ESPeasy - no problem.
You can send commands from Domoticz with parameters and receive it in ESPeasy.
You can transfer everything this way.
No compilation, only write in your browser and hit "Apply" button.

I like MySensors very much, but for wi-fi connected single sensors exists easier ways.

But my dream is feature for MySensor ethernet gateway, when I can send to gateway something like this:
http://gatewayip/control?cmd=23;5;24.5
which means = to_node, sensor_id, value.

Or opposite way, send from sensor to gateway command with domoticz sensor idx, type of domoticz value (svalue or nvalue ) and value itself and gateway will send to domoticz appropriate json command.

@kimot , I have to confess that I'm still a bit lost when I have to understand which language I'm using in each environment, but this is because I keep jumping from something to something else. Your explanation was very clear and allowed me to solve the "timing problem" if a few minutes.
At the same time... you gave me enough reason to test ESPeasy... and to say it all I have already installed another NodeMCU on the breadboard and starting right now to play :)
Thanks again

@gbuico
Ok.
Only do not forget, that ESPeasy webpage is mainly for setting, so it is not refreshed automatically like Domoticz. You must manually refresh it when check, if sensor value changed, for example.

My tests with ESPeasy stopped before beginning because I realized that I need a USB to TTL converter that I don't have a t moment... Delayed...

This gave me time to implement the change in NodeMCU sketch which addresses and solves the original problem of this topic.
I'm attaching here the second part of the modified sketch omitting the WiFi part.
In short, I defined a fake "switch" sensor in NodeMCU and I'm sending its modified status to Domoticz every 45 seconds (data timeout in Domoticz is 1 minute).
Important to underline that the new "fake sensor" can remain in the list of "not used" devices in Domoticz.
Here is the code:

// Start of the sensor specific code

#include <SPI.h>
#include <MySensors.h>
#include <pins_arduino.h>
#include <Bounce2.h>
#define CHILD_ID0 0
#define CHILD_ID1 1
#define CHILD_ID2 2
Bounce debouncer1 = Bounce();
Bounce debouncer2 = Bounce(); 
int oldValue1=-1;
int oldValue2=-1;
int tempo=millis();
int ultimo=0;
MyMessage msg1(CHILD_ID0, V_TRIPPED);
MyMessage msg2(CHILD_ID1, V_TRIPPED);
MyMessage msg3(CHILD_ID2, V_TRIPPED);
void setup()
{
  // Setup magnetic contact on D0 with pull-up
  pinMode(D0,INPUT_PULLUP);
  // After setting up reed switch, setup debouncer
  debouncer1.attach(D0);
  debouncer1.interval(5);
  // Setup magnetic contact on D1 with pull-up
  pinMode(D1,INPUT_PULLUP);
  // After setting up reed switch, setup debouncer
  debouncer2.attach(D1);
  debouncer2.interval(5);
}

void presentation()
{
	// Present locally attached sensors here
	present(CHILD_ID0, S_DOOR);
  present(CHILD_ID1, S_DOOR);
  present(CHILD_ID2, S_DOOR);
}


//  Check if digital input has changed and send in new value
void loop() 
{
  debouncer1.update();
  debouncer2.update();
  // Get the update value
  int value1 = debouncer1.read();
  int value2 = debouncer2.read();
  if (millis() > tempo + 45000)
  {
     Serial.print (millis());
     Serial.print (ultimo);
     tempo = millis();
     send(msg3.set(ultimo));
     ultimo = ultimo + 1;
     if (ultimo > 1)
     {
        ultimo = 0; 
     }
  }
  
  if (value1 != oldValue1)
	{
     // Send in the new value
     send(msg1.set(value1==HIGH ? 1 : 0));
     oldValue1 = value1;
	}
  if (value2 != oldValue2)
  {
     // Send in the new value
     send(msg2.set(value2==HIGH ? 1 : 0));
     oldValue2 = value2;
  }
}```

"and to say it all I have already installed another NodeMCU on the breadboard and starting right now to play"

"My tests with ESPeasy stopped before beginning because I realized that I need a USB to TTL converter that I don't have a t moment... Delayed..."

NodeMCU is with USB to TTL converter onboard.
Or how you programme it now?

I think with domoticz its might be enough to call sendHeartbeat() from your gateway every 30 seconds.
It should update the m_LastHeartbeatReceive of the HW and thats what mainworker uses when it defines if the HW should be "rebooted".

Here is a example(NOT TESTED):

#define HEARTBEAT_SEND_FREQUENCY 30000
unsigned long lastHeartBeatSend;
....
void setup()
{
  lastHeartBeatSend  = 0;
}
...
void loop()
{
  unsigned long now = millis();
  if(now - lastHeartBeatSend > HEARTBEAT_SEND_FREQUENCY)
  {
    sendHeartbeat();
    lastHeartBeatSend = now;
  }
}

@kimot , right now I'm using the Arduino IDE application which allows me to upload to NodeMCU just using the USB cable.
Reading the ESPeasy documentation I understand that this type of connection is not an option and you must have a USB to TTL interface.
I'd be very happy to hear that I don't need it... otherwise I'm going to get one on monday...

gbuico

@pjr , what you are suggesting is exactly what I wanted at the beginning..... but... my understanding from the first answer I got and for this https://www.domoticz.com/forum/viewtopic.php?f=42&t=9775&sid=1fea4af7b12f84f656ca4aa825eb6115
is that the sendHeartbeat() function is basically accepted but disregarded in Domoticz, meaning, would not create problems but not fixing the issues.
Of course this is my understanding and would be glad to have additional opinions/tests

pjr

@gbuico That thread is pretty old.

The current(and most likely working) functionality is implemented here:
https://github.com/domoticz/domoticz/commit/2d4e690c82b166ff8597a7deb44be17f3ad2560f#diff-a9f78798ba1bded6b56b3909b2a42848

gbuico

@pjr, thanks for your update. I went to check the solution proposed in the link you attached... and let me confess... got the concept, but it's complexity is currently not something at my reach.
Meaning.. as my solution is very small and working, for the time been I'll stick to it and spend my time for further function implementation.
My only worry... your example was just a few lines... understandable... how did they end up with 1700 lines of code or this?
Whatever.. I'l go back to it when I have some more time as I prefer an official implementation to a patch like mine...

@gbuico
USB to TTL serial is on board on NodeMCU and Wemos.

Download
ESPEasy mega dev.13

Upload to your NodeMCU using "FlashESP8266.exe" from .zip
Upload to NodeMCU

Use "....._normal_4096.bin" file

Power off - on !!! your NodeMCU ( reconnect USB cable )

Make basic setup:
With smart phone or notebook connect to your NodeMCU, which works like wifi acces point now ( name like "ESP_Easy_0" )
If password required - "configesp"
Type in browser address 192.168.4.1
wifi setup
Set your home wifi access info in config page.
You will see actual IP your NodeMCU in your wifi network.
Connect to this IP and make basic setup.
( you can set Fixed IP, IP of your Domoticz, etc )
ESPEasy setup
