The sketch works, but i still need the relay output inverted.
Changing the values from relay_on and relay_off does not do the trick -
As I said in my last post, you can put it in the receive() method of your node sketch. Basically, this will invert the relay state sent to PiMac only...
void receive(const MyMessage &message) { Serial.println("Received message..."); if (message.type == V_STATUS) { // Change relay state state = message.getByte(); digitalWrite(RELAY_PIN, state); send( msgRlay.set(state == 0 ? 1 : 0) ); } } -
I did not get it working the way i would like. I now used a different sketch.
here i had the same problem but i just set the relay_OFF from 0 to 1, and the Relay_ON from 1 to 0
And with this sketch it worked fine.#define MY_NODE_ID 1 // Enable debug prints #define MY_DEBUG // Enable and select radio type attached #define MY_RADIO_NRF24 //#define MY_RADIO_RFM69 #include <SPI.h> #include <MySensors.h> #include <DHT.h> #define CHILD_ID_HUM 1 #define CHILD_ID_TEMP 2 #define HUMIDITY_SENSOR_DIGITAL_PIN 6 unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds) unsigned long lastRefreshTime = 0; // Use this to implement a non-blocking delay function #define RELAY_1 3 // Arduino Digital I/O pin number for first relay (second on pin+1 etc) #define NUMBER_OF_RELAYS 1 // Total number of attached relays #define RELAY_ON 0 // GPIO value to write to turn on attached relay #define RELAY_OFF 1 // GPIO value to write to turn off attached relay 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() { dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN); metric = getConfig().isMetric; for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) { // Then set relay pins in output mode pinMode(pin, OUTPUT); // Set relay to last known state (using eeprom storage) digitalWrite(pin, loadState(sensor)?RELAY_ON:RELAY_OFF); } } void presentation() { // Send the Sketch Version Information to the Gateway sendSketchInfo("Badkamer", "1.3"); // Register all sensors to gw (they will be created as child devices) present(CHILD_ID_HUM, S_HUM); present(CHILD_ID_TEMP, S_TEMP); for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) { // Register all sensors to gw (they will be created as child devices) present(sensor, S_LIGHT); } } void loop() { boolean needRefresh = (millis() - lastRefreshTime) > SLEEP_TIME; if (needRefresh) { lastRefreshTime = millis(); 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); } 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; send(msgHum.set(humidity, 1)); Serial.print("H: "); Serial.println(humidity); } } } void receive(const MyMessage &message) { // We only expect one type of message from controller.

And with this sketch it worked fine.Your new sketch looks much better, glad you figured it out! :+1: You might want to remove the saveState() from your receive() method because the "saved -state" is not being used and this will prevent unnecessary writes to EEPROM which has a limited lifespan. Also, you might want to request the relay status from the gateway in setup() so the node will set the relay status to that of they gateway (i.e. the response to a request() sent in setup() will be handled by your existing receive() method).

So, is it working as expected? For example, if you turn the relay on and then reboot the node, does the node come up, ask for the relay status, receive relay on and then try to turn the relay on? You should be able to see this in the messaging sequence on the node.

No it doesn't do that. If i switch on the relay in pimatic then it goes on.
if i then rebot the node the relay stays off but the status in pimatic also changes to off.@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.
