Most reliable light switch
-
I'm moving to Vera+MySensors and will do all light management under MySensors.
Months before I raised a discussion to allow node to be operated individually, even if it's not connected to MySensor network. Unfortunately, it will not happen - once node is not connected - it will stop working.I definitely don't want to put my house in the dark because something went wrong. Does anybody created a reliable switch, based (maybe) on MySensor node + (say) Arduino ? Can anybody share good experience?

I am working on such a node, but am still in the programming and testing stage. I will come back here when I have positive results!

@DavidZH, sounds promising. Give me something for tests, I will spend next few months on this.

In mySensors V2.1 the basic sketch for a switch that will work even if the controller/gateway is down would look something like this
// Enable debug prints to serial monitor #define MY_DEBUG // Enable and select radio type attached #define MY_RADIO_NRF24 #define MY_TRANSPORT_WAIT_READY_MS 3000 //set how long to wait for transport ready. #include <SPI.h> #include <MySensors.h> #include <Bounce2.h> #define RELAY_PIN 4 // Arduino Digital I/O pin number for relay #define BUTTON_PIN 3 // Arduino Digital I/O pin number for button #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; MyMessage msg(CHILD_ID, V_STATUS); void setup() { pinMode(BUTTON_PIN, INPUT); // Setup the button pin digitalWrite(BUTTON_PIN, HIGH); // Activate internal pull-up // After setting up the button, setup debouncer debouncer.attach(BUTTON_PIN); debouncer.interval(5); pinMode(RELAY_PIN, OUTPUT); // set relay pin in output mode digitalWrite(RELAY_PIN, RELAY_OFF); // Make sure relay is off when starting up } void presentation() { // Send the sketch version information to the gateway and Controller sendSketchInfo("Relay & Button", "1.0"); // Register all sensors to gw (they will be created as child devices) present(CHILD_ID, S_BINARY); } void loop() { debouncer.update(); // Get the update value int value = debouncer.read(); if (value != oldValue && value == 0) { // check for new button push state = !state; //Toggle the state send(msg.set(state), false); // send new state to controller, no ack requested digitalWrite(RELAY_PIN, state ? RELAY_ON : RELAY_OFF); // switch the relay to the new state } oldValue = value; } void receive(const MyMessage &message) { // We only expect one type of message from controller. But we better check anyway. if (message.type == V_STATUS) { state = message.getBool(); // get the current state digitalWrite(RELAY_PIN, state ? RELAY_ON : RELAY_OFF); // switch relay to current state // Write some debug info Serial.print("Incoming change for sensor:"); Serial.print(message.sensor); Serial.print(", New status: "); Serial.println(message.getBool()); } }
