Momentary button to control lights



  • I have wrestled with this one a lot already.
    The idea: one battery powered node, with one push button (momentary).
    I want it to toggle the lights (controled by another node). Also I want the node to report battery status only when the button is pressed, otherwise sleep.
    I can't find what's wrong with my code. The node will not sleep, nor will it send messages when button is pressed. It will however check battery status on constant loop.
    Here's my code.
    If there's an easier way, I would GLADLY hear it.

    int BATTERY_SENSE_PIN = A0;  // select the input pin for the battery sense point
    
    //unsigned long SLEEP_TIME = 900000;  // sleep time between reads (seconds * 1000 milliseconds)
    int oldBatteryPcnt = 0;

    }
    


  • To start off with I would place the button on an interrupt pin and add an interrupt into the sketch. This way the interrupt can trigger the read of the battery voltage sense and also send that information along with the button change status.



  • @Topdawg2881 The button is on pin2 (=interrupt 0).
    I have a motion sensor that doesn't require this, but I will add

    #define INTERRUPT BUTTON_PIN-2

    Is that enough?



  • Someone better than me may be able to help further, but another thing you define NumberPushes as equal to 0 in the loop function. Every time the loop runs through it will set it equal to 0. I would define the integer as equal to 0 in the setup or prior to the setup so that your NumberPushes ++ function will actually count correctly.
    Also what does your debug info look like? If I remember correctly if you do not connect to the gateway the loop will not run correctly.



  • @Topdawg2881 Great point! Thanks for lending your eyes.
    Moving the numberPushes out of 'loop'. I'll see what it does. I'm also working to simplify the way the presses toggle between sending on-off.



  • Tried moving the numberPushes. Not working. I decided to tackle the "toggle problem" another way. Still no joy.
    Anyone have time to check my writing, much appreciated. Also if someone has code that works to make a momentary switch work like a toggle, that would be greatly appreciated.

    Why do you use button_pin and button_pin-2?


  • Mod

    @gohan BUTTON_PIN-2 was used in some early MySensors examples instead of digitalPinToInterrupt(BUTTON_PIN). Very ugly and we have gotten rid of it in the current examples but early users could still have sketches with that code.


  • Hero Member

    @MasMat Your remote switch node can never be sure if the light on the slave node is on or off (it may have been changed by the controller)

    To toggle a light from a remote I have found it easiest to place the toggle code in the node that controls the light not in the remote switch. You can then just send a node to node message from your remote to trigger the toggle.

    You could also use a node to node request to get the current state of the light but I think you will find it simpler using the first method.

    Without seeing your light controller node sketch it is hard to be specific but a very simple sketch could be like bellow.
    You can see all the work is done in the receive function.
    If the message is from your controller (through the gateway node 0) it will just set the light to the arriving state.
    If the message is from your remote (node 7) then it will toggle the light state.

     *  allow control from a remote switch

  • @Boots33 Will try that.
    My idea was to "let the switch be dumb" sending alternating 1 or 0. People tend to push on buttons until something happens :)

    Also I'm using this sketch as a run-up to building a two button remote.

    I can easily access the code the receiving node and have the remote node "just send 1or0" every time it's pushed?
    It will need more code if I have two buttons.

    PS where can I find the docs for "message.sender & message.destination" options?


  • Mod

    @MasMat I'm not sure if there is a more user-friendy documentation somewhere, but the source code has some information: https://github.com/mysensors/MySensors/blob/ff0953dd05b4f5e52e7d2c39ad23d207c896ea5e/core/MyMessage.h#L345

    Yes that is the best way. But it doesn't really need to change from 1 or 0 it can just send the same thing all the time.

    Also I'm using this sketch as a run-up to building a two button remote.
    I can easily access the code the receiving node and have the remote node "just >send 1or0" every time it's pushed?

    In the receive function of my sketch you can see that it will toggle on any message from node 7.
    So it does not matter whether you send a 1 or 0 it will still toggle. This will make your switch code simpler, it does not need to know what the current state is it can for example just send a 1 every time the button is pushed and the light will toggle.

    It will need more code if I have two buttons.

    Multiple buttons will be fine. you will just need to use message.sensor in the receive function to test for which child sensor the message is for.

    PS where can I find the docs for "message.sender & message.destination" >options?

    The core files as linked to by @mfalkvidd are the place to look.

    I used most of what you will need in previous posts and projects, have a read thru these.

  • @Boots33 I checked out your links. I love the outdoor touch controller!! That's awesome!

    I'm trying to figure out the "switch"-function, but Mysensors-docs nor Google cant find much.
    I'm trying to figure out how switch=>case works. I could use that to further my one (and two or more!) button remote. Where I get lost is why "case 4" is completely different from the other three?

    Any advice?

    I'm trying to figure out how switch=>case works.

    the switch/case is a standard arduino function. It can be very useful and sometimes much neater than using multiple if then else statements.

    I could use that to further my one (and two or more!) button remote.

    Yes it is well suited to that task.

    Where I get lost is why "case 4" is completely different from the other three?

    Any advice?

    Is it this you are referring to

    case 4:
             groupState = !groupState ;                   //Toggle the state
             send(msg.set(groupState), false);     // send new state to controller, no ack requested
             tone(buzzerPin, 1200, 60);                  //Play short beep to acknowledge touch
             break;    
    

    The first three case statements are sending direct node to node messages which are handled by the receiving node. The case 4 code is simply sending a standard binary switch message to my controller (Domoticz) and toggles the state of the switch in domoticz. I have that one switch set up as a group control switch in Domoticz so it turns on/off several light nodes at the same time. Sort of like a master control switch.

    As i indicated in that original post the sketch was still in it's early testing stages. While I still have not completely finished the project yet it has been out in the garden for some months and has shown no false triggers from either rain or even birds landing on the touch pad.

    Hope that helps. feel free to ask if you require any more info. MySensors node to node messages are really quite flexible once you get the hang of them. :)



  • All right. Been banging my head at this all day again.
    I seem to be sending the message from the node OK, but the receiving node appears to have intermittent problems. And for some reason, my gateway reboots at some "combinations".
    I have gone thru the send-node & receive-node code tens of times.
    Help & ideas appreciated. Plz excuse the finnish in the code :)

    To add, I would say there's nothing special in either serial output. I can elborate if nothing else appears.

    @MasMat said in Momentary button to control lights:

    All right. Been banging my head at this all day again.
    I seem to be sending the message from the node OK, but the receiving node appears to have intermittent problems.

    Yes your send message should be ok. You are sending a V_STATUS message from node 7 sensor 3 to node 3 sensor 3

    And for some reason, my gateway reboots at some "combinations".

    Not sure what could be causing that but you will need to sort that out to get stability. I have not experienced any issues with my gateway using node to node.

    I have gone thru the send-node & receive-node code tens of times.
    Help & ideas appreciated. Plz excuse the finnish in the code

    You will need to add code to separate the incoming messages from your controller and remotes as they will need to be treated differently. Messages from your controller will have the gateway (node 0) as the sender so this can be used.

    You have a lot going on in your receive function so maybe just put the code for the one node you are trying at the moment so it is easier to troubleshoot.

    Try something like this

    void receive(const MyMessage &message)
    {
      if (message.type == V_STATUS) {
       if (message.sender == 0) {                                        // check if message is from gateway (node 0)
        switch (message.sensor) {
            case 3:                                                      //incoming message is for WC relay (sensor 3) 
              stateWC = message.getBool();                               // get the new state
              digitalWrite(5, stateWC ? RELAY_ON : RELAY_OFF);           // 5 is RELAY_3 pin
              saveState(message.sensor, stateWC);                        // save sensor state
              break;
              
            /*-----Add case statements for other realys as needed ----*/
            
          }
        }
      else  {                                                           // message is not from gateway so must be from a remote
        switch (message.sender) {
            case 7:                                                     //incoming message is from WC remote (node 7)  
              stateWC = !stateWC;                                       // toggle light state
              digitalWrite(5, stateWC?RELAY_ON:RELAY_OFF);              // 5 is RELAY_3 pin         
              saveState(message.sensor, stateWC);                       // Store state in eeprom
              send(msgWC.set(stateWC), false);                          //Msg gateway aware of the change. No ack
              break;
              
            /*-----Add case statements for other remote nodes as needed ----*/
           
          }
        }
    
        // Write some debug info
        #ifdef MY_DEBUG
        Serial.print("Incoming change for sensor:");
        Serial.println(message.sensor);
        Serial.print("from node:");
        Serial.println(message.sender);
        Serial.print(" New status: ");
        Serial.println(message.getBool());
        #endif
      }
    }
    


  • @Boots33 That looks really clean. And you're right I have to comment out the stuff that's pre-prepared.
    The node is installed in a really tricky place and reprogramming is difficult (hence trying to solve everything beforehand). One day I'll learn to build & test first, install second...

    This morning I tested the setup again, with old settings and noticed the correct relay "fires" but doesnt really toggle. If I switch it off, it will come on but stay on regardless of presses. So the right node is receiving.

    I'll revise the code and re-test in a few...



  • This post is deleted!


  • @Boots33 So, added some tuff to keep the other relays working.
    The issue now is bouncing apparently.
    The send-node has delay but seems to fire a bunch of 1's (and 0's for some reason...?).
    Here's the lastest on the receiving end:

    void receive(const MyMessage &message)
    {
      if (message.type == V_STATUS) {
       if (message.sender == 0) {                                        // check if message is from gateway (node 0)
        switch (message.sensor) {
            case 3:                                                      //incoming message is for WC relay (sensor 3) 
              stateWC = message.getBool();                               // get the new state
              digitalWrite(5, stateWC ? RELAY_ON : RELAY_OFF);           // 5 is RELAY_3 pin
              saveState(message.sensor, stateWC);                        // save sensor state
              break;
            case 7:
              digitalWrite(RELAY_7, message.getBool()?RELAY_ON:RELAY_OFF); //Write to A0
              saveState(message.sensor, message.getBool());
              break;
            case 8:
              digitalWrite(RELAY_8, message.getBool()?RELAY_ON:RELAY_OFF); //Write to A1
              saveState(message.sensor, message.getBool());
              break;
            default:
              digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);
              saveState(message.sensor, message.getBool());
              break;
            /*-----Add case statements for other realys as needed ----*/
            
          }
        }
      else  {                                                           // message is not from gateway so must be from a remote
        switch (message.sender) {
            case 7:                                                     //incoming message is from WC remote (node 7)  
              stateWC = !stateWC;                                       // toggle light state
              digitalWrite(5, stateWC?RELAY_ON:RELAY_OFF);              // 5 is RELAY_3 pin

    @MasMat You could try increasing your delay time out to several seconds to see what happens (probably should use wait instead of delay as well) and maybe comment out the sleep line too. This may at least give you an idea of where to start.

    perhaps post some of the serial monitor output from the node.
