Array Relay Button Actuator

[maglo18]

In yours sketch state button should high next low then relay change state. I want to have possibility after button HIGH relay state change button LOW state relay change again

[jemish]

yes , I have same problem.

how can we use simple wall switch with relay to ON and OFF the lights.

[AWI]

For learning purposes: Instead of coding it for you, try the line of thought:

Now it changes with the toggle, so if "value" (switch) becomes high is changes the state of the relays, send the message to controller and stores it in EEPROM.

If you use a normal switch, you should change the state if when the "value" changes. So remember the last state of the switch and make it happen ;-)

btw :you need a variable to store the last button state and the physical position of the switch does not change if you update the relay switch from the controller..

[jeylites]

Just wondering any of you guys made progress in normal switch?

[rainair]

Hello this is my first post, but i follow my sensors for about 2 months.
Excuse my bad english.

For those how want use a normal in wall switch

just change the line:

if (value != Relays[i].oldValue && value == 0){

to

if (value != Relays[i].oldValue){

to

hope this was a bit helpfully

[jeylites]

@rainair, I tested it and it works! Thanks!!!

@jeylites said:

Relays[i].relayState = gw.loadState(i); // retrieve last values from EEPROM
digitalWrite(Relays[i].relayPin, Relays[i].relayState? RELAY_ON:RELAY_OFF); // and set relays accordingly
gw.send(msg[i].set(Relays[i].relayState? true : false)); // make controller aware of last status
gw.present(i, S_LIGHT); // present sensor to gateway
delay(250);

It's my idea, or shouldn't the sensor be presented to the gateway before sending it status?
Thanks! regards.

@gonzalonal

I don't think it matters. You could try flip "gw.send & gw.present" and see how it respond to the change.

[ewgor]

Wow ! this is what i was looking for ... Could anyone please share with us some Openhab settings for this wonderful Arduino sketch?
How can we assign in OH buttons to correspond to the physical buttons on the breadboard ?

Looking for any answer.

Thanks all!

[Cliff Karlsson]

How would I update this to work with 1.6?

[niccodemi]

@Cliff-Karlsson I recently started using 1.6 version, below is converted sketch. It works with momentary (pushbuttons) switches only.

Does anyone have sketch for toggle switches?

@jeylites Thanks, toggle switch works but there is issue when node boots / restarts. On 1st restart relays stay OFF, on 2nd come ON, on 3rd again OFF and so on. It seems that whatever happens during Setup is reversed in Loop. Hopefully someone can point out what should be changed in modified sketch.

@niccodemi

Hi!

I think the problem is you're not initializing oldValue to anything. It will then always be different than value in the loop, and state will change.

You should set oldValue to the same "state" as the loaded relayState in setup. Even better, only use relayState, and make it an int. You can do the same boolean evaluations anyway. 1 is true and 0 is false.

Edit:
Sorry, I forgot that this is a pushbutton, right? Then you should just make sure that oldValue and value are the same after setup is complete, ie HIGH.

[niccodemi]

@martinhjelmare

thanks, I understand what you mean but I don't know how to write it in sketch.

I tried inserting

Relays[i].oldValue = Relays[i].relayState;

at the end of Void Setup section but then sketch wouldn't compile. I get "name lookup of 'i' changed 'for' ISO for scoping [-fpermissive]" error. I get same error if I substitute Relays[i].relayState with loadstate.

[martinhjelmare]

@niccodemi

Put this on a line after pinMode() in setup function.

Relays[i].oldValue = digitalRead(Relays[i].buttonPin);

[niccodemi]

@martinhjelmare

Ok, there is an improvement. Relays now turn to same state as they were before reboot most of the time but not always. Sometimes they inverse - the one which was OFF turns ON and vice-versa. Sometimes (1 in 3) they switch ON and OFF (only for split second) in the loop function. See below screenshots:

This sketch is used with toggle button, same as on this photo.

[martinhjelmare]

@niccodemi

Could be the toggle is still bouncing at read time. Try increasing the debouncer interval. For example, double it until no more issues. Then decrease it in halves of what the last increase was until you see the issue again. This way you can try to find the smallest debounce time needed.

[BartE]

@niccodemi You can forget using the oldValue, because the debounce takes track of it's last status. When update() is called and a debounced pin-change is detect this function will return true otherwise it will send false.
Having a short delay each loop will stabilize the debouncers so your loop() can look like this:

void loop()
{
    for (byte i = 0; i < noRelays; i++) {
        if (debouncer[i].update()) {
            Relays[i].relayState = !Relays[i].relayState;
            digitalWrite(Relays[i].relayPin, Relays[i].relayState?RELAY_ON:RELAY_OFF);
            send(msg[i].set(Relays[i].relayState? true : false));
            // save sensor state in EEPROM (location == sensor number)
            saveState( i, Relays[i].relayState );
        }                 
    }
    wait(10);
}

[martinhjelmare]

@BartE

Why do you think it's better to add the wait than to increase debounce interval? Didn't know update returns a boolean, cool.
