Status of relay switch not maintained after ESP Restart

[fcoelho]

Hello,

I am using a relay connected to ESP and it is working fine, but if i power down and then powerup ESP8266 the lasts state it is not maintained.
In may opinion it should maintain ( or optional), Is it possible ? ( by writing the last status in eprom/flash)

Waiting news soon

TIA

Best regards,

F. Coelho

First of all: Thank YOU for this aweosome piece of software!
Second: Save specific pin/s state/s to EEPROM at runtime is the missing link in my project....

Hi again,
I found a workaround about this problem ...
The only thing is to add these two lines:

Code: Select all

            Settings.PinStates[event->Par1] = event->Par2 + 1;
            SaveSettings();

after 201 line in _P001_Switch
So when you change an state of GPIO via Domoticz with command:

Code: Select all

http://YOUR_ESP_ADDRESS/control?cmd=gpio,12,0

or

Code: Select all

http://YOUR_ESP_ADDRESS/control?cmd=gpio,12,1

these two lines will write corresponding GPIO states into flash ...
where "event->Par1" is GPIO pin, and "event->Par2 + 1" - pin state (0-default, 1 - ON, 2 - OFF (or reverse))
For me it works without problems.
Please developer/s correct me if I'm wrong.
Chears!

Interesting, but can you be more specific where to put those lines in the switch plugin ?
Because line 201 is different in different releases.

Would be good to see a few lines before and after these two lines so it is clear where to put them.

In _P001_Switch.ino:

Code: Select all

    case PLUGIN_WRITE:
      {
        String tmpString  = string;
        int argIndex = tmpString.indexOf(',');
        if (argIndex)
          tmpString = tmpString.substring(0, argIndex);
        if (tmpString.equalsIgnoreCase(F("GPIO")))
        {
          success = true;
          if (event->Par1 >= 0 && event->Par1 <= 16)
          {
            pinMode(event->Par1, OUTPUT);
            digitalWrite(event->Par1, event->Par2);
//<-------------------------------------------------------------------------------------------------------->
            Settings.PinStates[event->Par1] = event->Par2 + 1;        //Save GPIO settings
            SaveSettings();                                           			//Save GPIO settings
//<-------------------------------------------------------------------------------------------------------->
            if (printToWeb)
            {
              printWebString += F("GPIO ");
              printWebString += event->Par1;
              printWebString += F(" Set to ");
              printWebString += event->Par2;
              printWebString += F("<BR>");
            }
          }
        }

I thing there is no changes in this module recently....

Hi fellows.
Can you write me back how can I do the same in the last release R120?

[Justblair]

Or alternately...

In the advanced options switch on retain message...

Then add (or amend your existing rule) to publish topic: /device_name/GPIO/12 message 1

Assuming that you are switching the device. If you are commanding it from a HA server, add a retain to it's message settings.

You switch will recieve the retained message on connection to the mqtt server.

Please I need to know how to do this from the firmware in the last release R120, without the mqtt server, thanks!

[mcteusz]

I want to use it only that way:

Code: Select all

http://YOUR_ESP_ADDRESS/control?cmd=gpio,12,0

So I need to change source code.

[mcteusz]

It looks like we have to change:

Code: Select all

Settings.PinStates[event->Par1] = event->Par2 + 1;        //Save GPIO settings

to

Code: Select all

Settings.PinBootStates[event->Par1] = event->Par2 + 1;        //Save GPIO settings

[mlemes]

Compile but doesn't work

Compiles but doesn't work

Hello,

Very interested by this feature for persistant state on relay switch, i have patched the R120 release.

As said, the compil JOB is ok but with relays don't work.

any ideas ?

br,

[mcteusz]

My code looks like that:

Code: Select all

case PLUGIN_WRITE:
      {
        String log = "";
        String command = parseString(string, 1);

        if (command == F("gpio"))
        {
          success = true;
          if (event->Par1 >= 0 && event->Par1 <= 16)
          {
            pinMode(event->Par1, OUTPUT);
            digitalWrite(event->Par1, event->Par2);
            setPinState(PLUGIN_ID_001, event->Par1, PIN_MODE_OUTPUT, event->Par2);
            Settings.PinBootStates[event->Par1] = event->Par2+1;        //Save GPIO settings
            SaveSettings();
            log = String(F("SW   : GPIO ")) + String(event->Par1) + String(F(" Set to ")) + String(event->Par2);
            addLog(LOG_LEVEL_INFO, log);
            SendStatus(event->Source, getPinStateJSON(SEARCH_PIN_STATE, PLUGIN_ID_001, event->Par1, log, 0));
          }
        }

and it works. But one condition: no devices configured in "Devices" menu. When I set Switch input device, saving states wasn't working properly.

Hello All,

After we add the lines on in the switch.ino file i should re-flash the ESP to make it work?

Plus is it a correct thing that makes the GPIO to maintain the last status ?

Thank you,

Guys, there is a really good hardware fix for that problem. Use I2C expander, they keep their gpio output states, even while the ESP is rebooting.

Even if you can retain the value in flash, the GPIOs will still "click" through as the ESP boots (depending which ones), or at least go low during reboot. If you use I2C expander, the output stays unchanged until new command is received. At least the output will not change due to warmboots, which can always happen with esp easy

[toffel969]

The other options seems to retain the state on MQTT, that is if you use MQTT at all
