Hardware

• LOLIN D1 Mini V4.0.0-WEMOS (ESP8266)
• MOS FET (XY-MOS)
• SAMIORE DD4012SA 5V
• WAVGAT AC-DC 12V 3A (XPJ-02C)
• BTF-FCOB LED STRIP 528 12V LED

Software

• Home Assistant 2023.1.0
• Mosquitto 6.1.3 (MQTT 3.1.1)

Configuration System

Create file "config.h":

#ifndef CONFIG
#define CONFIG

const char* wifi_ssid = "wifi_ssid";
const char* wifi_pass = "wifi_pass";

const char* mqtt_server = "mqtt_server";
const char* mqtt_user = "mqtt_user";
const char* mqtt_pass = "mqtt_pass";
const int mqtt_port = 1883;

String clientId = "NAME-";

#endif

Configuration HA

Edit file "configuration.yaml":

mqtt:
  - light:
      name: 'Smart LED'
      state_topic: 'home/led/light/status'
      command_topic: 'home/led/light/switch'
      brightness_state_topic: 'home/led/light/brightness'
      brightness_command_topic: 'home/led/light/brightness/set'
      qos: 0
      payload_on: "ON"
      payload_off: "OFF"
      optimistic: false

Plan

• Connecting to Home Assistant MQTT
• Setup integrations MQTT Light
• Startup Config system
• Read config ini form SD
• Get a unique device name from Home Assistant
• Wiring diagram
• Automatic update over the air
• Printing the device body on a 3D printer
