Sample: ESP gateway with sensor

  • Hello,

    Does anybody have a sample of an ESP gateway with a local sensor attached?
    Currently I'm not able to find out how this can be done.

    I just want to send an increasing integer value to the controller (FHEM) each 5 minutes, to check if the connection is okay in the controller.

    @gloob I only commented out my network id/ passw/ and ip config

    A counter is included ;-)

     * The MySensors Arduino library handles the wireless radio link and protocol
     * between your home built sensors/actuators and HA controller of choice.
     * The sensors forms a self healing radio network with optional repeaters. Each
     * repeater and gateway builds a routing tables in EEPROM which keeps track of the
     * network topology allowing messages to be routed to nodes.

     * 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.
     * 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:
     * LED purposes:
     * - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs in your sketch, only the LEDs that is defined is used.
     * - 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
     * See for wiring instructions.

     * Not all ESP8266 modules have all pins available on their external interface.
     * This code has been tested on an ESP-12 module.
     * The ESP8266 requires a certain pin configuration to download code, and another one to run code:
     * - Connect REST (reset) via 10K pullup resistor to VCC, and via switch to GND ('reset switch')
     * - Connect GPIO15 via 10K pulldown resistor to GND
     * - Connect CH_PD via 10K resistor to VCC
     * - Connect GPIO2 via 10K resistor to VCC
     * - Connect GPIO0 via 10K resistor to VCC, and via switch to GND ('bootload switch')
      * Inclusion mode button:
     * - Connect GPIO5 via switch to GND ('inclusion switch')
     * Hardware SHA204 signing is currently not supported!
     * Make sure to fill in your ssid and WiFi password below for ssid & pass.
