ESP8266 Gateway motion sensor only working when "serial monitor" open



  • Hi every one

    I'm building a ESP8266 as a motion sensor and have got it working but only when the serial monitor is open in the Arduino IDE. if I don't have the monitor open it just stays in the motion detected state "1" this i can see using both MSYController and in the Vera Interface. As soon as i open the serial monitor it then goes back to "0" until it detects motion then it sends the correct info along to Vera working the way i want it to until disconnecting the serial monitor.

     * DESCRIPTION
     * The EthernetGateway sends data received from sensors to the WiFi link. 
     * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
     *
     * VERA CONFIGURATION:
     * Enter "ip-number:port" in the ip-field of the Arduino GW device. This will temporarily override any serial configuration for the Vera plugin. 
     * E.g. If you want to use the defualt values in this sketch enter: 192.168.178.66:5003
     *
     * LED purposes:
     * - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
     * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
     * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
     * - ERR (red) - fast blink on error during transmission error or recieve crc error

    I'm hoping some one can see some thing simple i have done.

    Thanks for any help

    @Opus40 Seems like you're mixing debouncer input and regular IO pin input.
    If you connect something like a PIR sensor you don't need to debounce the input; this is only required for mechanical switching parts like a push button.
    Also, debouncer is not connected to any IO pin, so the debouncer input won't work anyway.
    Not sure if this is causing your problems, but I would start using only digitalRead on the PIR input.



  • I started out with just the basics, but i get spammed out put of motion triggered and disregards if there is motion or not with the following code

    Thank you for the reply

    if i comment out all the debounce and re upload it then doesn't read the motion sensor and just out puts motion dectected at power up.
