✨ Key Features

• 🌡️ BME280 support (temperature, humidity, pressure)
• 💡 VEML7700 support (light intensity in Lux)
• 📡 MQTT support with modes: "active", "dummy", "inactive"
• ⚡ Sensor power reset via GPIO on data failure
• 🧪 Dummy mode for dev/testing without hardware
• 🔧 Central config.py with full runtime settings
• 🌐 WiFi fallback with independent credentials
• 📤 Adjustable MQTT send interval
• 🟢 Status LED and onboard LED indicators
• 📎 Flexible MQTT payload layout (MQTT_PAYLOAD_FIELDS)

---

⚙️ Setup

1. Flash MicroPython firmware onto your Pico W
2. Upload main.py and the lib/ directory to the board
3. Edit config.py to match your WiFi, MQTT, and sensor setup
4. Reboot the board → sensor starts automatically

🧠 Behavior Notes

• Sensors can be set to "active", "dummy", or "inactive" mode
• If a sensor returns None, the system performs a GPIO-based power reset
• MQTT is fully optional – in dummy mode, data is simulated but not sent
• You can modify the order and fields of MQTT messages easily

---

🛠️ Planned for Future Versions

• 📊 Web dashboard (Go backend in progress)
• 🌦️ Weather service integration (optional)
• 🧬 JSON-based sensor calibration import
• 🔋 Sleep mode and battery-friendly runtime

---

✅ Tested On

• 🌐 2.4 GHz WPA2 WiFi (Fritz!Box)
• 💡 VEML7700 (I2C @ 0x10, Gain 1/8)
• 🌡️ BME280 (I2C @ 0x76)
• 📡 Mosquitto MQTT broker (local, unencrypted)
• 💻 Thonny on Manjaro & MacOS
