  • interesting schematic. another way of controlling lights is:
    rewire standard light switch to low voltage input of arduino node
    use node's relay to control light, works even if you don't have neutral wire in light switch backbox.



  • Hi
    Thanks. The good thing is that the light circuit is independent from Arduino and Raspberry. That was the main reason behind it. I was supposed to add a description but something went wrong and I only published the schematic. Anyway, I have got a problem with a script for this solution.
    Anybody can help with the programming?



  • @alco plenty people here ready to help

  • @JeeLet Hi. First, you probably should have started another thread rather than hijacking this one since the situation is barely related.

    Looking here, I found that !MCO:PRO:RC=1 is caused mainly by calling send() or wait() inside the receive() function.
    I have not completely understood how things are happening but I think at best you're receiving a message while processing the current one. From several sources on this forum, you should keep your receive() function small. Process the content of the message and do all the work in loop().

    I would probably do something like that, but ⚠ I didn't compile and test the code :

    You may have to tweak the conditions and tests so that your sensor is always in a consistent state, but that should resolve the recursion error message.

    Hello
    I just saw your message.
    nothing seen in my mailbox.

    yes that's true for another post, but the quest has the same 🙂
    to see if moderator or alco finds useful, is to do so.

    Thanks for paying attention to my problem, cool.

    I tested the sketch and the errors "MCO: PRO: RC" its part .... bingo

    but as nature hates emptiness, something else happens (nothing serious)

    .... a story of disregard for a local change / command / switchover of the TL

    I look better at your modifications to understand the arduino.
    thank you for the comments in the scketch

    my test model

    Well!! where is the notifications button



  • Yes errors on the commands given through domoticz
    only one in three and taken into account

    terminal copy serial

    Changement entrant pour le capteur:3, New status: 0
    Changement entrant pour le capteur:3, New status: 1
    Changement entrant pour le capteur:3, New status: 0
    Changement entrant pour le capteur:3, New status: 0
    Changement entrant pour le capteur:3, New status: 0
    Changement entrant pour le capteur:3, New status: 1
    Changement entrant pour le capteur:3, New status: 0
    Changement entrant pour le capteur:3, New status: 0
    

    ...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));
                }
            }
        }
