Hey everyone,
I have a few on the Mini Rboards working very well for control of a few light switches, using Vera 3 as my controller. What is driving me and the family a little crazy is how the manual light switches have to work so that they operate the Mini Rboard.
Here is my sketch:
// Example sketch för a "light switch" where you can control light or something
// else from both vera and a local physical button (connected between digital
// pin 14 and GND).
// This node also works as a repeader for other nodes
#include <MySensor.h>
#include <SPI.h>
#include <Bounce2.h>
#define RELAY_PIN 4 // Arduino Digital I/O pin number for relay
#define BUTTON_PIN 14 // Arduino Digital I/O pin number for button -A0 which is D14
#define CHILD_ID 1 // Id of the sensor child
#define RELAY_ON 1
#define RELAY_OFF 0
Bounce debouncer = Bounce();
int oldValue=0;
bool state;
MySensor gw;
MyMessage msg(CHILD_ID,V_LIGHT);
void setup()
{
gw.begin(incomingMessage, AUTO, true);
// Send the sketch version information to the gateway and Controller
gw.sendSketchInfo("Relay & Button", "1.0");
// Setup the button
pinMode(BUTTON_PIN,INPUT);
// Activate internal pull-up
digitalWrite(BUTTON_PIN,HIGH);
// After setting up the button, setup debouncer
debouncer.attach(BUTTON_PIN);
debouncer.interval(5);
// Register all sensors to gw (they will be created as child devices)
gw.present(CHILD_ID, S_LIGHT);
// Make sure relays are off when starting up
digitalWrite(RELAY_PIN, RELAY_OFF);
// Then set relay pins in output mode
pinMode(RELAY_PIN, OUTPUT);
// Set relay to last known state (using eeprom storage)
state = gw.loadState(CHILD_ID);
digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
}
/*
* Example on how to asynchronously check for new messages from gw
*/
void loop()
{
gw.process();
debouncer.update();
// Get the update value
int value = debouncer.read();
if (value != oldValue && value==0) {
gw.send(msg.set(state?false:true), true); // Send new state and request ack back
}
oldValue = value;
}
void incomingMessage(const MyMessage &message) {
// We only expect one type of message from controller. But we better check anyway.
if (message.isAck()) {
Serial.println("This is an ack from gateway");
}
if (message.type == V_LIGHT) {
// Change relay state
state = message.getBool();
digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
// Store state in eeprom
gw.saveState(CHILD_ID, state);
// Write some debug info
Serial.print("Incoming change for sensor:");
Serial.print(message.sensor);
Serial.print(", New status: ");
Serial.println(message.getBool());
}
}
So to use mu current light switches, I have to turn them on and then off, for the light to operate. If I only turn the switch on, the light will operate, but to operate it again I have to turn the switch off and then on again.
I have looked into a momentary switch, but to get the ones to fit are quite expensive...
Is there a way to alter the sketch to make it work better? IE can I have the sketch open the relay when the binary switch is connected, and then close the relay when it is disconnected?
thanks for your help
