Noob here, so I tried to do my due diligence before posting

My goal is to use NodeMCU as wireless gateway to connect to Home Assistant on a Pi. I would also to use this NodeMCU as a Relay Actuator, but we are not there yet-- I'm having trouble getting NodeMCU to successfully get set up as a gateway.

It seems like the NodeMCU is successfully connecting to my network... it's being assigned a local IP address which I can ping, and it shows up on my router's list of connected devices.

From what I have searched, the error messages indicate there's an issue connecting with the radio. That confuses me, because the NodeMCU has the radio connected... there are no wires for me to mess up.

Below is my sketch and the info from the serial monitor. (I redacted my SSID and password, no other changes made)

Am I missing something? Thank you!

/*
 * 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.

 *******************************
 *
 * REVISION HISTORY
 * Version 1.0 - Henrik Ekblad
 * Contribution by a-lurker and Anticimex,
 * Contribution by Norbert Truchsess <norbert.truchsess@t-online.de>
 * Contribution by Ivo Pullens (ESP8266 support)
 *
 * 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 default values in this sketch enter: 192.168.178.66:5003
 *
 * 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 received. In inclusion mode will blink fast only on presentation received
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or receive crc error
 *
 * See https://www.mysensors.org/build/connect_radio for wiring instructions.
 *
 * If you are using a "barebone" ESP8266, see
 * https://www.mysensors.org/build/esp8266_gateway#wiring-for-barebone-esp8266
 *
 * Inclusion mode button:
 * - Connect GPIO5 (=D1) 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.

@mfalkvidd wow, thank you for your help! I totally misunderstood the radio scenario.

I uploaded my "Gateway + Relay Actuator" sketch and updated the radio section as you suggested. We are connected! I can ping the node.

Now my challenge is getting connected to Home Assistant on my Pi. I'm thinking I need to do some permissions work within HA/Pi.

Thank you!
