Relay Actuator with momentary (pulse) action

drradkin

What do I need to edit in the relay actuator sketch in order to turn the relay on for about .5 seconds then turn it immediately back off?

        digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);

to

@mfalkvidd Hello, today I used your suggestion, but in the meanwhile the code of RelayActuator.ino has changed a little bit.
So this is what has changed and how I adjusted. This could be useful to another beginner like me.

Change:

digitalWrite(message.getSensor()-1+RELAY_PIN, message.getBool()?RELAY_ON:RELAY_OFF);

to:

if (message.getBool() == RELAY_ON) {
    digitalWrite(message.getSensor()-1+RELAY_PIN, RELAY_ON);
    wait(500);
    digitalWrite(message.getSensor()-1+RELAY_PIN, RELAY_OFF);
    }

Here is my code, which I used to hack my dishwasher so I can turn it on via my smart home system. The code is designed to work well with the Mozilla WebThings gateway and the Candle project, which is based on MySensors. But it but should work just fine with any smart home controller that supports MySensors.

Morning all,

I'm smashing together 3 types of sketches here (3 x Dimmer, 4 x Button, 2 x relay) and am struggling with this 'momentary' relay action. The relays do not fire at all.

Everything is presented to the controller (Openhab) via an RS485 gateway, and the dimmer and buttons work and feedback their states. The log output shows that this device is receiving a 0 and 1 from Openhab on its relay nodes (7 and however, still no actuation.

I wonder if someone was able to take a cursery glance at my code. The relay sections of code are bracketed with // Relay

@adds666 In receive(), note how you use relayPin:

  if (message.type == V_STATUS) {

    if (message.sensor == 7)  {
      if (message.getBool() == RELAY_ON) {
        digitalWrite(message.getSensor()-1+relayPin, RELAY_ON);

relayPin is an array (const uint8_t relayPin[] = {3, 7};). If you use it without specifying an index, like you do here, you get a pointer to the first element, not the value of an element.

Something like digitalWrite(relayPin[message.getSensor()-7], RELAY_ON) should work here. getSensor() returns 7, because you already checked for that two lines above. 7 - 7 = 0, which results in relayPin[0] and toggles the relay on pin 3.

Also, note that you load the current relay state from EEPROM positions 0 and 1 in setup():

for (uint8_t i = 0; i < MAX_RELAY; i++) {
  pinMode(relayPin[i], OUTPUT);
  //digitalWrite(relayPin, loadState(i)?RELAY_ON:RELAY_OFF);
  if (loadState(i) == RELAY_ON) {

But you save the state to byte 7 in receive():

saveState(message.sensor, message.getBool());

Hope this helps you out!

@BearWithBeard said in Relay Actuator with momentary (pulse) action:

digitalWrite(relayPin[message.getSensor()-7], RELAY_ON)

Many thanks for coming back @BearWithBeard, its a huge help.
So my logic for correcting the State problem at the bottom would be to do the same calculation to get them in to 0 and 1.

saveState(message.getSensor()-7, message.getBool());

Compiled correctly and then uploaded and it works! Fantastic. The following sketch has 3 dimmers, 4 buttons and 2 relay outputs.

Thank you very much - I'm learning
