All Lights On instead of Off and Off instead of ON

[dsaleeb]

Hi Guys,

I got everything to compile and work except the initial status of the relay board lights is ON and when I ask alexa to turn each one ON then the on board lights goes off, So everything is backwards. I tried 2 different relays, any help appreciated.

Here is my code:

#include <ESP8266WiFi.h> #include <ESP8266WebServer.h> #include <WiFiUdp.h> #include #include "switch.h" #include "UpnpBroadcastResponder.h" #include "CallbackFunction.h"

const int relayS1Pin = D1; const int relayS2Pin = D2; const int relayS3Pin = D3; const int relayS4Pin = D5;

// prototypes boolean connectWifi();

//on/off callbacks void relayS1On(); void relayS1Off(); void relayS2On(); void relayS2Off(); void relayS3On(); void relayS3Off(); void relayS4On(); void relayS4Off();

// Change this before you flash const char* ssid = "MyWiFiName"; const char* password = "********";

boolean wifiConnected = false;

UpnpBroadcastResponder upnpBroadcastResponder;

Switch *relayS1 = NULL; Switch *relayS2 = NULL; Switch *relayS3 = NULL; Switch *relayS4 = NULL;

void setup() { Serial.begin(9600);

// Initialise wifi connection wifiConnected = connectWifi();

if(wifiConnected){ upnpBroadcastResponder.beginUdpMulticast();

pinMode(relayS1Pin, OUTPUT); pinMode(relayS2Pin, OUTPUT); pinMode(relayS3Pin, OUTPUT); pinMode(relayS4Pin, OUTPUT);

// Define your switches here. Max 14 // Format: Alexa invocation name, local port no, on callback, off callback relayS1 = new Switch("office lights", 80, relayS1On, relayS1Off); relayS2 = new Switch("bedroom lights", 81, relayS2On, relayS2Off); relayS3 = new Switch("hallway lights", 82, relayS3On, relayS3Off); relayS4 = new Switch("bathroom lights", 83, relayS4On, relayS4Off);

Serial.println("Adding switches upnp broadcast responder"); upnpBroadcastResponder.addDevice(*relayS1); upnpBroadcastResponder.addDevice(*relayS2); upnpBroadcastResponder.addDevice(*relayS3); upnpBroadcastResponder.addDevice(*relayS4); } }

void loop() { if(wifiConnected){ upnpBroadcastResponder.serverLoop();

relayS1->serverLoop(); relayS2->serverLoop(); relayS3->serverLoop(); relayS4->serverLoop(); } }

void relayS1On() { digitalWrite(relayS1Pin, HIGH); // turn on relay with voltage HIGH }

void relayS1Off() { digitalWrite(relayS1Pin, LOW); // turn off relay with voltage HIGH }

void relayS2On() { digitalWrite(relayS2Pin, HIGH); // turn on relay with voltage HIGH }

void relayS2Off() { digitalWrite(relayS2Pin, LOW); // turn off relay with voltage HIGH }

void relayS3On() { digitalWrite(relayS3Pin, HIGH); // turn on relay with voltage HIGH }

void relayS3Off() { digitalWrite(relayS3Pin, LOW); // turn off relay with voltage HIGH } void relayS4On() { digitalWrite(relayS4Pin, HIGH); // turn on relay with voltage HIGH }

void relayS4Off() { digitalWrite(relayS4Pin, LOW); // turn off relay with voltage HIGH }

// connect to wifi – returns true if successful or false if not boolean connectWifi(){ boolean state = true; int i = 0;

WiFi.mode(WIFI_STA); WiFi.begin(ssid, password); Serial.println(""); Serial.println("Connecting to WiFi");

// Wait for connection Serial.print("Connecting ..."); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); if (i > 10){ state = false; break; } i++; }

if (state){ Serial.println(""); Serial.print("Connected to "); Serial.println(ssid); Serial.print("IP address: "); Serial.println(WiFi.localIP()); } else { Serial.println(""); Serial.println("Connection failed."); }

return state; }

Code looks ok to me. Wondering what you are using for relays? Are they high level or low level triggers?

Hi Joe,

I tried two different relays

Sorry but cant determine if they are high or low level triggers. Relays come in high an low level triggers. Some are both depending on a jumper. You could just take 5 volts to power the relays , then apply 5 volts to a channel input to see if relays turns on/off as you apply the 5 volts. I know i have purchased which were supposed to be high trigger levels only to find out they were low. Joe

I tried to switch the HIGH and LOW in the code but still didn't work.

Ex.

void relayS1On() { digitalWrite(relayS1Pin, LOW); // turn on relay with voltage HIGH }

void relayS1Off() { digitalWrite(relayS1Pin, HIGH); // turn off relay with voltage HIGH }

[kakopappa]

Try these

1. Make a simple test app to test the relay
2. Use the multi-meter or LED to check whether digitalWrite really works.
3. Check the power supply. make sure adruino is getting enough power to turn on the relay.

I solved the problem.

On my relays High is off and Low is on.

void S1On() { Serial.print("Switch 1 on ..."); digitalWrite(relayS1Pin, LOW); }

void S1Off() { Serial.print("Switch 1 off ..."); digitalWrite(relayS1Pin, HIGH); }

void S2On() { Serial.print("Switch 2 on ..."); digitalWrite(relayS2Pin, LOW); }

void S2Off() { Serial.print("Switch 2 off ..."); digitalWrite(relayS2Pin, HIGH); }

I'm working on another project and I might need your help @joeman2116 @kakopappa

Now I'm trying to add the following to this code

*web access to turn on/off from a browser *using http widget mobile app to create on/off on screen shortcuts *using Blynk to remotely turn the devices on/off

Would you guys be interested to contribute to this project?

I Re-worked the code a little to set relays to low at startup. It is as follows:

// Modified by DrexProjects

const int relayS1Pin = D1; const int relayS2Pin = D2; const int relayS3Pin = D3; const int relayS4Pin = D5;

// prototypes boolean connectWifi();

//on/off callbacks void relayS1On(); void relayS1Off(); void relayS2On(); void relayS2Off(); void relayS3On(); void relayS3Off(); void relayS4On(); void relayS4Off();

// Change this before you flash const char* ssid = "dlink"; // Replace with your router name const char* password = "********"; // Add your password here

boolean wifiConnected = false;

UpnpBroadcastResponder upnpBroadcastResponder;

Switch *relayS1 = NULL; Switch *relayS2 = NULL; Switch *relayS3 = NULL; Switch *relayS4 = NULL;

digitalWrite(relayS1Pin, HIGH); // sets the digital pin 1 on digitalWrite(relayS2Pin, HIGH); // sets the digital pin 2 on digitalWrite(relayS3Pin, HIGH); // sets the digital pin 3 on digitalWrite(relayS4Pin, HIGH); // sets the digital pin 4 on

// Define your switches here.

Serial.println("Adding switches upnp broadcast responder"); upnpBroadcastResponder.addDevice(*relayS1); upnpBroadcastResponder.addDevice(*relayS2); upnpBroadcastResponder.addDevice(*relayS3); upnpBroadcastResponder.addDevice(*relayS4); } }

void loop() { if(wifiConnected){ upnpBroadcastResponder.serverLoop();

relayS1->serverLoop(); relayS2->serverLoop(); relayS3->serverLoop(); relayS4->serverLoop(); } }

void relayS1On() { digitalWrite(relayS1Pin, LOW); // turn on relay with voltage HIGH }

void relayS4Off() { digitalWrite(relayS4Pin, HIGH); // turn off relay with voltage HIGH }

// connect to wifi – returns true if successful or false if not boolean connectWifi(){ boolean state = true; int i = 0;

WiFi.mode(WIFI_STA); WiFi.begin(ssid, password); Serial.println(""); Serial.println("Connecting to WiFi");

// Wait for connection Serial.print("Connecting ..."); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); if (i > 10){ state = false; break; } i++; }

if (state){ Serial.println(""); Serial.print("Connected to "); Serial.println(ssid); Serial.print("IP address: "); Serial.println(WiFi.localIP()); } else { Serial.println(""); Serial.println("Connection failed."); }

return state; }
