💬 AC-DC double solid state relay module

[johnym30]

@Boots33 Thanks they are working now!!!!!!!
Unfortunately i dont know about coding, i am more of a hardware guy, so i will just have to live with that.Hoping that in the future someone will write something and share it with us.
Thank you once more.

[Boots33]

@johnym30 There are only a few changes to be made to make the hardware switches more reliable. @hek showed in this post some code that could be used.

First you will need to add a line near the top of your sketch to allow the node to execute the loop part of the sketch even if no transport uplink is established. This code needs to be placed before #include <MySensors.h>

#define MY_TRANSPORT_WAIT_READY_MS 3000     //set how long to wait for transport ready.

The number at the end of the line is used to set how long to wait in milliseconds. I have found that my nodes will usually connect within 3 seconds.

Then you need to modify the code in the loop part of your sketch.

if (value != oldValue) {
    state =  !state;                                                  // Toggle the state
    send(msg.set(state), false);                          // send new state to controller, no ack requested
    setRelayState(RELAY_PIN, state);                // switch the relay to the new state
    saveState(CHILD_ID, state);        // Store state in eeprom
    // Write some debug info
    printStateChangedDebug(CHANGE_STATE_SOURCE_SWITCH, CHILD_ID, value);
    oldValue = value;
  }
  

  if (value2 != oldValue2) {
    state2 =  !state2;                                         // Toggle the state
    send(msg2.set(state2), false);                 // send new state to controller, no ack requested
    setRelayState(RELAY_PIN_2, state2);     // switch the relay to the new state
    saveState(CHILD_ID_2, state2);     // Store state in eeprom
    // Write some debug info
    printStateChangedDebug(CHANGE_STATE_SOURCE_SWITCH, CHILD_ID_2, value2);
    oldValue2 = value2;
  }

@Boots33 Will you please upload your complete code. It is difficult to see the finale solution then I read all the posts.

[Boots33]

@folkestorp I have no node to try it on but the code will look like this. perhaps you can test it and let us know if it works. I have just placed it in the original code of a few posts up

 * DESCRIPTION
 *
 * Script for double SSR relay board by Aproxx
 * https://www.openhardware.io/view/77/AC-DC-double-solid-state-relay-module
 * https://forum.mysensors.org/topic/3671/ac-dc-double-solid-state-relay-module
 * Control 2 circuits either from controller or from physical buttons connected on pins 4 & 7
 * Optional DS18b20 is connected on pin 8
 * 
 *  HISTORY :
 * xx/xx/2016 original version by Aproxx
 * 08/02/2016 upgraded to MySensors 2.0 by mr_const
 * 08/30/2016 changes by Nca78 :
 *        - fixed initialization of physical buttons/debouncer status
 *        - centralized pin status change for relays in setRelayState method
 *        - centralized debug information for state changes in one method + added debug info when changed by physical switches
 *        - added #ifdef MY_DEBUG before each Serial.print (saves prog memory when not in debug mode) and F() macros for debug strings (saves RAM when in debug mode)
 *        - added #define USE_TEMP_SENSOR to make temperature sensor optional (not used if line is commented)
 *        - put back #define for repeater feature
 *        - add #define TEMPERATURE_ROUNDING for custom temperature rounding

@Boots33 I have test your code without temp sensor. It works perfect. Thank you!!!

[Boots33]

@folkestorp great. Thanks for reporting back.

[XerOps]

I got a problem. I connected the board directly to ä powersource but the adapter doesnt output 5V . The part before just output 230 v just fine. Any one has any sugestions on whatsapp im missing?

[Nca78]

@XerOps do you have 230V on the input pins of the HLK ?

[XerOps]

@Nca78 Well yeah, trough a completly soldered board tough, with both fuses and the varsisitator.

[laucarlier]

Hi,

Many thanks for sharing this project!

Is this also possible to post a picture of the other side of the PCB in order to get a better idea on how the Arduino is soldered?

Kind regards,

Hi Tonerre33,

Thanks a lot for sharing the picture of your project!

I really like the idea of the way you put the PSU and the arduino so that you win a lot of space!

Kind regards,

Hi,

it is very cool project. I assembled one but when I test it this is what I get:

I guess it shows that radio has unreliable power. Please advise how should I debug?

[rzylius]

The problem dissapeared when I changed 4.7uf capacitator to 47uf. works great!

[rzylius]

Where to find a sketch with temperature read?

[mfalkvidd]

@rzylius could you be a bit more specific? Do you want a way to read the temperature of the solid state relay?

[SensibleHeat]

Hello,

Thank you for sharing this project. I have built it and am testing it on my outdoor lights.
.
I have three issues I can't seem to figure out and am hoping others may have had similar problems and figured out a fix.

First some background. I built a double relay board and have 120V 60 hz power. I am controlling it through MyNodes 2.0. I am using an unedited version of the source code. My networks includes about 7 other nodes that are only measuring temperature. Half of them are set up to be repeater nodes. I was suspicious that I may be getting interference from the other nodes causing the problem but have had the same problems with the other nodes disabled.

Here are the issues I am trying to fix.

1. I am finding that the relays will not stay in the position they are controlled to be in. Mostly they close when controlled to be open but also they are opening when controlled to be closed.
2. When in a closed state relay 1 flickers every few minutes. I have replaced this relay and still have the same issue.
3. The hardwired switch control isn't working for me work. The switch only causes a flicker in the lights.

Any suggestions? For me Half of the fun in the projects is trouble shooting and making them work. I'll send updates on any fixes I come across.

[zombiee77]

Hi and Thank you for the Board!!!

My question is, kann I user an usual old fashioned Light switch or must I buy a push button??

[zombiee77]

@nca78
I used the code and it worked well with the remote control.-
I can switch a LED (for testing purposes attached instead of a SSR) on and off.
If I want to switch the LED with a push button I fail.

This is what I have changed:

#define RELAY_PIN 4 // Arduino Digital I/O pin number for relay
#define RELAY_PIN_2 5
#define BUTTON_PIN 3 // Arduino Digital I/O pin number for button
#define BUTTON_PIN_2 7

And this is the serial output I get, after I press the button:

This is an ack from gateway
