Hi!
I am trying to build a RFM69 gateway with wemos d1 and keyestudio RFM69 shield. The code is compiled and uploaded but I see no serial log nor wifi connection. It just doesn't show anything. Can I set up the gateway? Thanks in advance.

• arduino ide 2.3.2
• mysensors 2.3.2
• esp8266 board 2.7.4 (ver 3.1.2 won't upload the code)

The RFM69 shield is from Keyestudio.
https://wiki.keyestudio.com/KS0515_Keyestudio_FSK_Wireless_Shield_RFM69HCW_868mhz(Black_and_Eco-friendly)

Here's the code.

// Enable debug prints to serial monitor
#define MY_DEBUG

// Use a bit lower baudrate for serial prints on ESP8266 than default in MyConfig.h
#define MY_BAUD_RATE 9600

// Enables and select radio type (if attached)
#define MY_RADIO_RFM69
#define MY_RFM69_FREQUENCY RFM69_868MHZ // Set your frequency here
#define MY_IS_RFM69HW

#define MY_GATEWAY_ESP8266

#define MY_WIFI_SSID "**"
#define MY_WIFI_PASSWORD ""

// Set the hostname for the WiFi Client. This is the hostname
// it will pass to the DHCP server if not static.
#define MY_HOSTNAME "WEMOSD1_GW"

// Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
#define MY_IP_ADDRESS 192,168,0,146

// If using static ip you can define Gateway and Subnet address as well
#define MY_IP_GATEWAY_ADDRESS 192,168,0,1
#define MY_IP_SUBNET_ADDRESS 255,255,255,0

// The port to keep open on node server mode
#define MY_PORT 5003

// How many clients should be able to connect to this gateway (default 1)
#define MY_GATEWAY_MAX_CLIENTS 20

#include <MySensors.h>

void setup()
{
// Setup locally attached sensors
}

void presentation()
{
// Present locally attached sensors here
}

void loop()
{
// Send locally attached sensors data here
}

Hi!
I am trying to build a 6-light-sensor & 2 ch relay node to control my old dehumidifier. When I disassembled it, I found 2 switches (power & mode) and 6 leds which can be used to control and report status. Also it has 5v output.

Below is the sketch I came up with. It is showing the light sensor values as below but can't see 2ch relay switches. Am I missing something?

// Enable debug prints
#define MY_DEBUG
// Enable and select radio type attached
#define MY_RADIO_RF24
//#define MY_RADIO_RFM69
//#define MY_RS485
#define MY_NODE_ID 7
#define RELAY_PIN 3 // Arduino Digital I/O pin number for power relay (connected to D3)
#define RELAY_PIN 4 // Arduino Digital I/O pin number for mode relay (connected to D4)
#define NUMBER_OF_RELAYS 2 // Total number of attached relays (2 in this case)
#define RELAY_ON 1 // GPIO value to write to turn on attached relay
#define RELAY_OFF 0 // GPIO value to write to turn off attached relay

I am sharing my sketch. Based on the sketch below, I am using this led light to show air quality status (good for green, normal for yellow and bad for red). This sketch is just a switch so you should make some automation in HA.

@electrik Wow! You gave me a clue! Thanks!!

Hi!
I'm trying to build a traffic light led module node on a arduino pro mini 5v. I am currently using a temperature/humidity node without a problem with raspberry pi ethernet gateway.

Below is the sketch I'm working on. Its function is only to toggle in home assistant. When uploaded, it seems to be communicating with the gateway but doesn't show up in home assistant.

I'd like to know if there's something wrong with the sketch.
Thanks in advance!
