New scketch for water level + control valves



  • Hi,

    As the title already mentioned, I would like to build a sensor which will measure the waterlevel and send it to my gateway. If the waterlevel is sufficient, my gateway has to send the signal to open the valve and start the pump.
    I would like to use a combination of 2 scripts (Relay and distance sensor)

    I have tested the sketch, but it only returns a distance when I press a button in Domoticz.

    The sketch I've used:

    /**
     * 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.

    Please could you help me, to combine the sketches and help me with my learnig curve 😉

    Hello @Naitsirhc,

    I've put the correct tags around your sketch. I'm currently @work so I'm not able to have a in depth look at your sketch.


  • Hardware Contributor

    @Naitsirhc Hi!
    Have a look at https://forum.mysensors.org/topic/4651/my-basement-flooding-alarm/. This is exactly what @GertSanders posted some days ago. There is a .ino file with code attached at the bottom of the post.

    The problem with your code might be that you only send values when it has changed. So if the value is the same all the time (no flood) it will not send any new value.

    if (dist != lastDist) {
    

    Also check serial log to see that its not 0 or any other error value all the time coming from distance sensor.

    Another tip might be adding a wait(50); after or before reading the distance and see if that makes any difference.



  • Thank You all,

    I will try the sketch (and try to understand it....LOL)
    I need only need to measure the water level once or twice a day. So I will figure it out how it has to be done.

    Thanks again



  • Hi back again,

    Tried to upload the sketch. unfortunatly the copiler returns an error:
    'sendSketchInfo' was not declared in this scope
    Googled for an answer. And found an solution, for installing a new library.
    I installed:
    MySensors 2.0.0
    Mysensors_development
    But it doesn't work.

    Can you help me please

    I turned of the LED pin (I don't need it)

    The compiler does his job till the last line:
    saveState(PUMP, PumpStatus);

    which returns:
    exit status 1
    'saveState' was not declared in this scope

    What can I do to make this error disappear

    Thanks in advance


  • Contest Winner

    @Naitsirhc Your running MySensors 1.5 ??? try:

      gw.saveState(WATERLEVEL, Distance);
    


  • Hi

    First of all, thanks for all the answers.

    Started from skratch again. Downloaded the new arduino IDE.Some Libraries (NewPing and Mysensors) and finaly the sketch compiled 😄
    I uploaded it to the Nano and then expected to see something on the serial monitor....

    Too bad...Oh right. removed slashes for MyDebug and MyDebug_Verbose...

    Presto.

    Unfortunatly I see in serial monitor:

    Starting sensor (RNNNA-, 2.0.0)
    TSM:INIT
    TSM:RADIO:OK
    TSP:ASSIGNID:OK (ID=32)
    TSM:FPAR
    TSP:MSG:SEND 32-32-255-255 s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=bc:
    TSM:FPAR
    TSP:MSG:SEND 32-32-255-255 s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=bc:
    TSM:FPAR
    TSP:MSG:SEND 32-32-255-255 s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=bc:
    TSM:FPAR
    TSP:MSG:SEND 32-32-255-255 s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=bc:
    !TSM:FPAR:FAIL
    !TSM:FAILURE
    TSM:PDT
    TSM:INIT
    

    Too bad. What have I done wrong? Is it possible to see the distance in serial monitor and to see if a relay turned on or off?

    EDIT:
    Upgraded my Gateway also to 2.0

    Stil no succes 😞

    Output from Gateway:

    0;255;3;0;9;Starting gateway (RNNGA-, 2.0.0)

  • update:

    Adapted the old distance sensor sketch to the 2.0 library and upladed it and connected to my PC. Also connected the gateway 2.0 to raspberry (Domoticz).....
    Allright it works....I do get distance in my serial monitor and in domoticz.

    Now try to upload the basement alarm sketch...See what happens...
