Multi Button Relay switch

Terence Faul

Thanks a stack, it is slow.

If I did want to restore the relay state how would I change the code?

At the moment if I leave that code in when the arduino boots it cycles each relay on and then off, instead of just restoring the previous state

Anthony Straw

go for SSR instead of hk mechical relay it will stop working after 10,000 clicked ... cheap brand

I got the same question as @Terence-Faul, How to change the code to have the Relay to restore its previous state. I tried a couple of things but can't seem to get it to work. Thanks @BulldogLowell for the script !

BulldogLowell

@jeylites ,

so, try to look over the example just above the one that worked for @Terence-Faul

It included saving states to EEPROM and retrieving them in setup( ).

C.r.a.z.y.

How do you seperate relay power?

What is your solution to drop 220v AC to 5v DC?

jeylites

@C.r.a.z.y. You could get a USB power adapter... see Ebay link below. On my current setup, I'm using a 2.1A+1A Dual USB 2-Ports. I use the the 1A port for the Arduino and the 2.1A port for the relays. On the relay board, you have VCC, IN1 & GND. IN1 gets connected to the Arduino, VCC to the second power supply or power port. The GND is shared between both power ports. Hope that helps!

@BulldogLowell

I have gone through the script like 8 times with no luck at all. Are you suggesting the mistake in in the EEPROM retrieval section ?

@jeylites You are initializing the relays with the "Start State of Relays" and afterwards with the state from EEPROM. That could cause the on/off switching at startup.

Chaotic

To Elaborate on what AWI said

@jeylites said:

digitalWrite(relayPin[i], RELAY_OFF); //Start State of Relays
...
digitalWrite(relayPin[i], relayState[i]? RELAY_ON:RELAY_OFF);

You have both of those lines in your Setup() The first one is setting the relay to off the second one is checking the EEPROM value

Remove the first one and the problems should be fixed (assuming the EEPROM data is correct.

jeylites

@Chaotic , @AWI

//digitalWrite(relayPin[i], RELAY_OFF); //Start State of Relays
I did as you say and removed the above line but still no luck. The relay turns on/off on every start up. And it doesn't hold the last state. I compared My Sensor's script with Bulldogs's and found lots of similarities but can't seem to find the fault.

AWI

@jeylites I took a deeper look at your sketch and think I found the cause. You are writing and reading from different EEPROM locations. The "standard" way is to use the "Sensor number" as location reference. Whereas the sketch also used "relayPin[i]" to store values. I took the liberty of adapting your sketch as I found it hard to read. Also added storing the value in EEPROM after pushing a button.
I have not build the circuit so were not able to test it in real life :) Have fun and let me know if it worked for you.

@AWI Thank you so much. This is awesome! I bet so many people is going to benefit from this script.

I had some time off today and ran the script. It didn't work the fist time, but I made some minor changes to "Relay_ON & Relay_OFF and also activated " Start State of Relays" and it worked. I'm guessing it didn't the first time because my relays are Active Low.

Also, while toying around with it, I realize that it doesn't send back the status of the relay & actuator to the Controller (Homeseer). On Homeseer, suppose you have it at “ON” there is a maker that indicates its state and vice versa. I noticed that worked on Binary Switch & Motion Sensor but not on Relay & Relay Button Actuator sketch. Don't know if it's a script or Homeseer issue though.

Again, thanks, everyone who helped pointing out the problem. I'm new to My Sensor and I'm glad to be here and making progress.

#define RELAY_ON 0 //switch around for relay HIGH/LOW state
#define RELAY_OFF 1

pinMode(Relays[i].relayPin, OUTPUT);

@AWI I just realize another thing. The is a long delay for the sensor to sends its presentation during inclusion mode. Is there something to do with the number of sensors in one node or sketch? Essentially, I would have to reset the sensor several times to get it discovered.
It's pretty quick on a single or double sensor node.

AWI

@jeylites I don't have experience with Homeseer as controller.and don't fully understand your questions, so just give it a shot..

The multi relay sketch is firing a large amount of messages to the gateway/ controller during presentation. If you have transmission problems and/or a slow controller it could get into trouble. I suggest you monitor on the serial port of the sensor if there are "fail" messages. (need to turn on DEBUG = default) If there are it could be a power problem or...

The real fun (and headache) is in the debugging :) The serial monitor can give you lost of clues

Depending on how long is "long". there are also 250 ms delays between the individual presentations of the relays. ..'
have fun ;)

jeylites

@AWI

I think you're right on the controller. I've been getting some glitch running HS3 on Mac. I don't know if its a plugin or software issue, but I will like to get to the bottom of it. In addition, a buddy of mine is loaning his Vera edge so I might run some test on that too.

Meanwhile, will take your advice on serial monitor and will let you know the outcome. Cheers!

Thanks for sharing.
I have a problem with this scripts. My relay auto start then off every gateway check node. How can i fix it?
Thanks

jeylites

@quocanhcgd

You will need to activate this line pinMode(Relays[i].relayPin, OUTPUT);

It should work right after.

quocanhcgd

I activated this line but no result. may be openhab work wrong? What the controller you use?

@quocanhcgd

I have tested the sketch on vera Ui7 & Homeseer but I don't know why it takes a very long time for the sketch to send individual presentations of the relay to the controller. Sometimes it doesn't send it at all. I have changed power supply as @AWI suggested and the relays are not connected to the Arduino at this time. Still nothing. Anyone here knows what the fail messages are. Below is the serial messages I got....
