MYSrelayboard using a bipolar relay

A Former User last edited by

Hi, in order reduce current consumption i'm trying to implement a relaynode
with a bipolar relay. Ths relay relay has one coil (20msec pulse) to set relay on and another coil (20msec pulse) to set the relay off. I also included a feedback contact so the arduino can determine in which position my relay is. I'm a newbie to C so have not been able to work out how to implement this using the existing relaysketch. Anyone have any good good ideas to proceed?

In addition to my message above, I'm getting a bunch of errors when I try to compile the above binary sketch. Hope to hear from some one.

@derksuh Sorry to hear but your sketch looks good. Are you using the MySensors development branch? If not, doing so will probably fix the behavior because there was a bug in the 2.0 release that prevented messages from being sent (i.e. the request()) in the setup() method of a sketch. Once you upgrade to the MySensors development branch, if it still doesn't behave properly, please post the messages logged by the node, with #MY_DEBUG enabled.

@mfalkvidd Thank you for your valuable suggestions - they all look very relevant. Perhaps I am overlooking something in the documentation, but I wonder if any existing controllers out there will get the node's relay outputs in the right state again after a node restart, if it always starts up in off state. Besides that, how can I reliably detect communication in the node, such as I_HEARTBEAT/I_HEARTBEAT_RESPONSE? As far as I know, such internal messages do not arrive through the recieve(...) API function. I will need to see some incoming messages (also from existing controller implementations) - otherwise I would get timeouts. Best regards Lasse

@Marco-MicrOchip-Acquadro Great. Maybe the relay example with button can help you get started. It works with MySensors 2.x.

@BartE Adding the extra code done the job, now its working great. Thank you for your help! The final working code if someone wonders is: #include <SPI.h> #include <MySensor.h> #include <DHT.h> #include <Bounce2.h> #include <MySigningNone.h> #include <MyTransportNRF24.h> #include <MyTransportRFM69.h> #include <MyHwATMega328.h> #define NODE_ID 1 #define CHILD_ID_HUM 0 #define CHILD_ID_TEMP 1 #define CHILD_ID_RELAY 2 #define RELAY_PIN 3 #define BUTTON_PIN 4 #define HUMIDITY_SENSOR_DIGITAL_PIN 2 //unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds) #define RELAY_ON 1 // GPIO value to write to turn on attached relay #define RELAY_OFF 0 // GPIO value to write to turn off attached relay MyTransportNRF24 radio(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW); MyHwATMega328 hw; MySensor gw(radio, hw); Bounce debouncer = Bounce(); int oldValue=0; bool state; MyMessage msg(CHILD_ID_RELAY,V_LIGHT); DHT dht; float lastTemp; float lastHum; boolean metric = true; MyMessage msgHum(CHILD_ID_HUM, V_HUM); MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP); void setup() { gw.begin(incomingMessage, AUTO, true); dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN); gw.sendSketchInfo("Combo", "1.0"); gw.present(CHILD_ID_HUM, S_HUM); gw.present(CHILD_ID_TEMP, S_TEMP); pinMode(BUTTON_PIN,INPUT); digitalWrite(BUTTON_PIN,HIGH); debouncer.attach(BUTTON_PIN); debouncer.interval(5); gw.present(CHILD_ID_RELAY, S_LIGHT); metric = gw.getConfig().isMetric; digitalWrite(RELAY_PIN, RELAY_OFF); pinMode(RELAY_PIN, OUTPUT); state = gw.loadState(CHILD_ID_RELAY); digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF); } unsigned long lastCheckTimestamp = 0; // setup stuff void incomingMessage(const MyMessage &message) { if (message.type == V_LIGHT) { digitalWrite(RELAY_PIN, message.getBool() ? RELAY_ON : RELAY_OFF); gw.saveState(1, message.getBool()); Serial.print("Incoming change for sensor:"); Serial.print(message.sensor); Serial.print(", New status: "); Serial.println(message.getBool()); } } void loop() { gw.process(); if (debouncer.update() && debouncer.read() == 0) { gw.send(msg.set(gw.loadState(1)?false:true), true); // Send new state and request ack back } // Check if the minimal sample period has been passed if ((lastCheckTimestamp < (millis() - dht.getMinimumSamplingPeriod()) ) || lastCheckTimestamp > millis()) { lastCheckTimestamp = millis(); // do the normal stuff after the delay float temperature = dht.getTemperature(); if (isnan(temperature)) { Serial.println("Failed reading temperature from DHT"); } else if (temperature != lastTemp) { lastTemp = temperature; if (!metric) { temperature = dht.toFahrenheit(temperature); } gw.send(msgTemp.set(temperature, 1)); Serial.print("T: "); Serial.println(temperature); } float humidity = dht.getHumidity(); if (isnan(humidity)) { Serial.println("Failed reading humidity from DHT"); } else if (humidity != lastHum) { lastHum = humidity; gw.send(msgHum.set(humidity, 1)); Serial.print("H: "); Serial.println(humidity); } } }
Launch a function instead of control a relay, is it possible ?

Sounds possible. Just try it, and enjoy learning.

On UI5 this information is shown. Something must be wrong with the Repeater device files in the UI7 branch.

@floris can you post the final sketch you used? I am having the same issue.
