Binary Switch Timer
-
I am trying to use the Binary switch example to monitor the state of a Switch .I want to be able to measure the length of time the switch is not in its normal state e.g.. "how long was the door/window open" I have found numerous timer sketch's but they seem to be for timing when something should happen . Anyone have suggestions or example sketch's

@mikeg291 You can store the epoch time on state open (now();) and again on state close and subtract those values.
But you have to init the time module with the GW time first. something like this sketch should work
#include <MySensor.h> #include <SPI.h> #include <Bounce2.h> #include <Time.h> #define CHILD_ID 3 #define BUTTON_PIN 3 // Arduino Digital I/O pin for button/reed switch MySensor gw; Bounce debouncer = Bounce(); int oldValue=-1; time_t lastSwitchTime = 0; void receiveTime(unsigned long controllerTime); bool timeReceived = false; // Change to V_LIGHT if you use S_LIGHT in presentation below MyMessage msg(CHILD_ID,V_TRIPPED); void setup() { gw.begin(); // 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 binary input sensor to gw (they will be created as child devices) // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage. // If S_LIGHT is used, remember to update variable type you send in. See "msg" above. gw.present(CHILD_ID, S_DOOR); // Make sure we get the system time, repeat request every 5 seconds until we have a valid time gw.requestTime(receiveTime); unsigned long lastRequest = millis(); if ((millis() - lastRequest) > 5000) { gw.wait(100); gw.requestTime(receiveTime); lastRequest = millis(); } lastSwitchTime = now(); } // Check if digital input has changed and send in new value void loop() { debouncer.update(); // Get the update value int value = debouncer.read(); if (value != oldValue) { Serial.print("Switch was "); Serial.print(oldValue ? "ON" : "OFF"); Serial.print(" for: "); Serial.print(now() - lastSwitchTime); Serial.println(" seconds"); lastSwitchTime = now(); // Send in the new value gw.send(msg.set(value==HIGH ? 1 : 0)); oldValue = value; } } // This is called when a new time value was received void receiveTime(unsigned long controllerTime) { // OK, set incoming time Serial.print(F("Time value received: ")); Serial.println(controllerTime); setTime(controllerTime); timeReceived = true; }

BartE I hope this isn't a test because I just failed . I get the following error when compiling .

@mikeg291 Mm sorry must have been a copy/past error when posting the sketch i 've made an update you can try again.

That fixed the issue. It works great. To further enhance the sketch I added an alarm ,however I get an error as shown . Is there a way ; once the sent value of the alarm is set high that it is not changed based on future reading . requiring an acknowledgement or reset .
#include <MySensor.h> #include <SPI.h> #include <Bounce2.h> #include <Time.h> #define CHILD_ID 3 #define BUTTON_PIN 3 // Arduino Digital I/O pin for button/reed switch const int alarmtime = 15; MySensor gw; Bounce debouncer = Bounce(); int oldValue=-1; time_t lastSwitchTime = 0; void receiveTime(unsigned long controllerTime); bool timeReceived = false; // Change to V_LIGHT if you use S_LIGHT in presentation below MyMessage msg(CHILD_ID,V_TRIPPED); void setup() { gw.begin(); // Serial.begin(9600); // 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 binary input sensor to gw (they will be created as child devices) // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage. // If S_LIGHT is used, remember to update variable type you send in.
