ESP8266 NodeMCU WiFi IoT Garage Door Opener Relay with Cayenne


#21

At the moment I have a solid state relay that doesn’t seem t work. It can only be wired one way.

I can flip it but let me ask. When you plug it up should it start beeping and then “Closing Garage!”

This is what it looks like when I hit the reset button.

Closing Garage!

It runs closing garage right out of the gate.


#22

// assuming you wire your relay as normally open
if (currentValue == 0) {
digitalWrite(13, HIGH);

the “currentValue == 0” was missing the zero.

Seems to be working better now.

However I keep losing connection to it. “can not connect to remote device”. It seems like if I push the button a few times it fast it can can crashes the NodeMCU (say you want stop the garage half way). I’ll drop pings to it.

Then the pings to the NodeMCU come back but it is hit or miss if will start working again.


#23

It has been 15 minutes and it hasn’t come back. Of course while I am filming I have to hit the button a million times. I have seen it when after a couple presses it stops responding. It must be timing, like I push the button when it is doing something else and jacks it up.


#24

It’s possible 5V coming off the ESP8266 to power the relay might be too much of a drain and causing the ESP8266 to reboot or the USB Power Supply itself doesn’t have enough amps.

There is some talk about how to wire the relay with a 5V Power supply with a resistor and transistor here: http://www.instructables.com/id/ESP8266-WiFi-relay-switch/ or maybe someone with more electrical knowledge than me can chime in on a better way to wire this.


#25

Yea, I have a problem, I got this error “‘Cayenne’ was not declared in this scope” Could you please help me? Here the code:

define CAYENNE_PRINT Serial // Comment this out to disable prints and save space

// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token[] = “token”;
// Your network name and password.
char ssid[] = “ssid”;
char password[] = “password”;

void setup()
{
Serial.begin(9600);
Cayenne.begin(token, ssid, password);
}

void loop()
{
Cayenne.run();
}


#26

Do you have #include <CayenneEthernet.h> or whatever your connection method is in there somewhere?


#27

@adam, when I include <CayenneEthernet.h> , and try to verify, I got a error too,
CayenneEthernet.h: No such file or directory, the same if I include <CayenneWifiClient.h>
I don’t know what can I do to fix it,
Thank you.

Have you installed the Cayenne library in your Arduino IDE? Click Sketch>Include Library>Manage Libraries… then search for Cayenne.
