3. Help with pool solar controller code

Help with pool solar controller code

  • JCH

    I am trying to create a pool solar controller and have run into a couple of issues which i cannot figure out as im not a very good coder 😀

    I am going to have a ds18b20 waterproof temp sensor in the pool pump shed which is taped to the pool pipe to reflect the pool temp.
    This node is also going to have a lcd screen which displays the pool temp and well as the roof solar temp.
    I am going to have a 2nd node on the roof measuring the roof water temp and that node is going to send its data back to the controller and also direct to the node (not sure if this is the best way or not) so that it can be displayed on the lcd screen.
    The roof node is powered by solar and reports every 30 seconds and then goes back to sleep.

    Here is the code for the roof sensor

  }

    Now the problem i am having is as the pool node doesn't sleep it basically just waits to receive a message from the pool controller and once it does it reports both sensors and then goes back to start again.... so if the roof node goes down for whatever reason then the whole thing stops working.
    What is the best way around this?

    Also i wasnt getting alot of the messages and figured ouit from the logs that it was bcasue it was being repeated by the gateway... so to get around that i changed

    if (message.sensor == 1)

    to

    if (message.sensor <= 1)

    to include the gateway ( 0 )

    again i am not sure if thats the best way forward?
    I really am only a weekend hobbyist so not too sure that i am going about this the right way

    Hi @JCH

    Have a look at the code of your pool node. You are hiding all your temperature measurement and LCD display logic inside the if (message.type==V_TEMP) condition. So if no message is received, this node will do nothing but continue to listen.

    Besides that - please prove me wrong - I think it is a bad idea to process so much code inside receive() and especially to send out messages from there. This can cause all sorts of weird stuff including recursive loops. You also shouldn't use sleep() on nodes which are supposed to listen to incoming messages. Use the non-blocking wait() instead if you have to.

    I would suggest to move all the code which is related to the temperature sensor and the LCD display into the main loop(), fetch the temperature, send it and update the LCD on fixed intervals.

    In your receive() function, listen for the incoming message only. If you receive a new temperature value, store it in a global variable (for simplicity) like roofTemp which you can access in the loop(). That's all you need to do here.

    You could also set a boolean flag like receivedMessage to true in receive() when a new messages comes in if you want to update the LCD immidiately. But in general, keep it short.

    Also i wasnt getting alot of the messages

    Could be caused by putting the node to sleep aswell. The MCU will propably need less than a second to process all the instructions in your sketch. If you put the node to sleep, it will be in a state where it can't process incoming messages most of the time.

    Thanks @BearWithBeard

    Ok how does this look.......

    One more question i need help with......
    On the roof sensor , do i send the nodes different msg. or the same?

    @JCH Remove the serial print from receive - I had issues with that before......

    Really this is more complicated than it needs to be. You just need the roof node to send temp to the controller and then the controller can relay that to the pool node.

    Also, what is the reason the roof node sends temp every 30 seconds? Thermal inertia of pool systems is not that fast (even boiling a kettle with a little water is comparitively slow). So why not send every 5 minutes instead? Or just when it hits a max/min temp for your purpose? This will be much less drain from the solar battery.

    The 30 seconds is while im only testing it.... once it is working as expected i will change the time

    EDIT: I think the push button wont work if there is a wait for sleep.... Is there anyway around this?

    0 skywatch 1 Reply

    @JCH You need to use pins D2 and D3 for the buttons and have them attached as interrupts. Interrupts will 'interrupt' the sleep cycle and perform whatever action you have told it to do in your sketch. The only other way to interrupt sleep that I know of is a timer that wakes at set (or random) intervals.

    Remember that void loop() is not running in sleep mode, so no amount of checking buttons pins will work here during that time.

    @skywatch Will the interrupt work with wait or only sleep?
    I ended up going down a rabbit hole trying to implement a non breaking timer as below... it all seems to be working now except the button doesnt switch states everytime.... sometimes have to press it 2 or 3 times?

    @JCH I haven't tried interrupt with wait so I can't really say for sure. But it works for sleep 100%.....

    I don't know how you got to the point you are at now, but it is easy to reflash an arduino and so I suggest the following.....

    1. Start again from the begining with the new knowledge you have.
    2. Look at similar examples and learn how they work.
    3. Build your code slowly.

    Start by getting just the buttons to work and monitor them in the serial window or by attaching leds with limiting resistors to the output pins you want to use for the relays. Then add debounce and check all is working. Then add the lcd display and test until working. Keep adding a bit at t time so it is easy to know what you changed and if it worked as expected.

    When I am doing this I save the sktech after each working version and then update the sketch version for the next addition. It allows me to easily go back to working system if I get unexpected results (which I do in a lot of cases!).....

    Ok i need help again please... I cannot get to the bottom of my last little problem......

{ 
  pinMode(BUTTON_PIN, INPUT);
  // Activate internal pull-up
  digitalWrite(BUTTON_PIN, HIGH);
  pinMode(BUTTON_PIN_2, INPUT);
  // Activate internal pull-up
  digitalWrite(BUTTON_PIN_2, HIGH);
 // pinMode(BUTTON_PIN_3, INPUT);
  // Activate internal pull-up
 // digitalWrite(BUTTON_PIN_3, HIGH);
 
  debouncer.attach(BUTTON_PIN);
  debouncer.interval(5);
  debouncer2.attach(BUTTON_PIN_2);
  debouncer2.interval(5); 
  debouncer3.attach(BUTTON_PIN_3);
  debouncer3.interval(5);
  oldValue = debouncer.read();
  oldValue2 = debouncer2.read();
  oldValue3 = debouncer3.read();

    As soon as i tired to add a 3rd button and debouncer the whole code crashes.... as soon a a comment out the above lines it goes good again.... thoughts?

    Here is the whole code (havent tidyed it up yet 😉

    Edit.... Does mysensors use pin 9 for anything? as soon as i try to use it as an input the radio seems to not be communicating with the controller?
    I loaded a bounce sketch to test the button and pin and it works fine untill i reload my sketch.
