    • RE: Wifi Gateway on Arduino

      Don't be scared 🙂 , this time I'm not here to ask for help but to contribute.
      The good news is that with all the hints received, yesterday I've been able to compile and upload the sketch to NodeMCU.
      One year later (today 🙂 ) I defined the NodeMCU in Domoticz,searched for sensors and everything is now properly working.
      My next step now is to add a second sensor to the same NodeMCU but, should I face problems, I think I should start another topic to avoid confusion.
      Bottom line... thank you for the help provided and here is the final working sketch that I hope will help someone else

      /**
       * 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
       * Contribution by a-lurker and Anticimex,
       * Contribution by Norbert Truchsess <norbert.truchsess@t-online.de>
       * Contribution by Ivo Pullens (ESP8266 support)
       *
       * 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
       *
       * See http://www.mysensors.org/build/esp8266_gateway for wiring instructions.

       * Not all ESP8266 modules have all pins available on their external interface.
       * This code has been tested on an ESP-12 module.
       * The ESP8266 requires a certain pin configuration to download code, and another one to run code:
       * - Connect REST (reset) via 10K pullup resistor to VCC, and via switch to GND ('reset switch')
       * - Connect GPIO15 via 10K pulldown resistor to GND
       * - Connect CH_PD via 10K resistor to VCC
       * - Connect GPIO2 via 10K resistor to VCC
       * - Connect GPIO0 via 10K resistor to VCC, and via switch to GND ('bootload switch')
       *
        * Inclusion mode button:
       * - Connect GPIO5 via switch to GND ('inclusion switch')

    • RE: Wifi Gateway on Arduino

      Just a quick additional information.
      While deeply testing the full functionality, I realized that if the NodeMCU goes out of main
      power AND the magnetic contact connected to D3 (GPIO 0) is closed, the loaded configuration is lost. I found out that usage of GPIO 0, 2, 15 is deprecated because these pin have a meaning during reboot.
      For this reason I moved my switch to D0 (GPIO 16) and modified accordingly the sketch of my previous post.
      Sorry

    • RE: Domoticz data timeout

      @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

    • RE: Wifi Gateway on Arduino

      @mfalkvidd , thanks for your answer which is really good news. If your mention on using esp8266 as a shield means that someone is buying a shield with esp8266 to plug directly on Arduino, this is exactly what I had in mind since I'm terrible with soldering.
      Having said so, I found that shield and I'd love to share it here just to get advices but I don't know which is the right way to show it without breaking the rules of the forum (advertising).
      Could you please advise me on how I can share what I found?
      Thanks for your time

    • RE: Domoticz data timeout

      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>

      Bounce debouncer2 = Bounce(); 
      int oldValue1=-1;
      int oldValue2=-1;
      int tempo=millis();
      int ultimo=0;

      MyMessage msg2(CHILD_ID1, V_TRIPPED);
      MyMessage msg3(CHILD_ID2, V_TRIPPED);

      {
        // 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);

        // 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;

      @gbuico said in Wifi Gateway on Arduino:

      Having no practical experience with NodeMcu I just think of it as something not powerfull enough to do its job, then I realize that in some areas of the house I'll just need to monitor 2-3 magnetic switches... and you seem to say that this works fine for you

      The NodeMCU board contains a regular esp8266, which has more than enough oomph to handle the wifi connection, some sensors and the mySensors stack! Don't worry!

      I had a quick look and the link you've posted seems to sell the regular NodeMCU boards.

      @Yveaux , I received my modules today at lunch time and a couple of hours later the NodeMCU is up and connected to WiFi, so I think it's proper to acknowledge that your step-by-step guide is extremely precise.
      If I can contribute, the main issue I had to face has been a TSP initialization failure caused by the attempt to open the radio module which is not there in my setup.
      Surely my fault but I went straight to define SSID and password ad indicated... but I didn't read carefully the other setup parameters...
      Bottom line... thank you... now going to add the sensor logic and integrate everything in Domoticz

      @dzjr this is what I also had in mind but... are you using a commercial sensor or you built one yourself?
      When I say "sensor" I mean the device that is currently in the soil.
      I checked different commercial sensor and all seem to become unusable in a very short time... this is why I'm really interested in your solution

      @dzjr , glad you solved your problem .. but... can you please share which sensor are you using to measure the soil moisture?
      I found a lot of sensor suitable for in-house measuring but nothing for outside which is not becoming unusable very quickly.
      Whatever information is highly appreciated...

    • Soil moisture sensor

      Hi everybody.
      I'm trying to add the irrigation system of my terrasse to the existing domotic system.
      The idea is to measure the soil moisture of each big flowerpot and send water accordingly.
      Since a couple of weeks I'm reading tons of web pages on this subject but everything seems to be related to indoor applications and most of them under evaluate the corrosion aspects of a sensor constantly remaining in a moist soil outdoor.
      So, here is the question to the group.
      Does anybody have experience in this area and is willing to share it?
      Of course, cost wise, I'm not looking for a very expensive sensor, but I'm ready to spend what is needed to have a solid solution, corrosion resistant.
      Any idea or suggestion?
      Thanks

      @gohan , if I understand well, in a relay like the one of the attached picture, you removed the jumper, connected +5V to JD and GND, In1, In2, 3,3V on the other connector?
      If this is true I'll be happy because this is how I'd have done.... but I couldn't find anybody confirming it...

    • Relay connection to NodeMCU V3

      Good afternoon everyone. I'm here to get suggestions from those of you who are more experienced than me in electronics.
      The problem is simple. I have an ESP8266 (NodeMCU V3 Lolin) and I'd like it to drive a 5Vdc relay.
      Searching in internet I can find many samples like this... BUT.... some of them are connecting the positive wire of the relay to Vcc (3,3V), some others to VU (5V) and all say it's perfectly working.
      If I find two solution to the same problem I get worried 🙂
      Specifically, should I connect Vcc, I'm not sure that the relay would switch in a secure way.
      At the same, if I connect it to VU, I'm asking myself if this would not create a problem since the pin triggering the relay is coming from a GPIO pin and should be 3.3V
      Please forgive me if this is a stupid question but I have to experience in this area.
      Thanks in advance

      @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...

      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

      @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...
