Fully optional smart weather station

DIY Smart Weather Station with Home Assistant integration A feature-rich, high-precision ESP8266-based Smart Weather Station with a modern responsive Web Dashboard, dynamic sensor detection, customizable moving-average filters, Home Assistant MQTT Auto-Discovery, full backup/restore capability, and hardware factory reset logic.   ✨ Features Environmental Monitoring: Temperature, Relative Humidity, Barometric Pressure (sea-level compensated), Air Quality (TVOC, eCO2, AQI), Luminosity (lux), Wind Speed, Wind Gust, Wind Direction, and Rain Gauge (hourly, 24h rolling, and total). Independent Dual-Timer Engine:Fast, dedicated timer for Anemometer pulse processing (independent of I2C read cycle). Configurable I2C sensor read cycle for environmental data. Configurable Moving Average (Smoothing):Wind Speed: Ring buffer rolling average with configurable sample count (N). Wind Direction: Circular mean calculation (sin/$\cos$ vectors) preventing 0∘/360∘ boundary glitches across N samples. Instantaneous Gust Tracking: Daily wind gust records real peak pulses before averaging. Web UI & Diagnostics:Glassmorphism dark UI built with HTML5/CSS3/JavaScript (no external dependencies). Tasmota-style live Debug Console with interactive command input. Mobile-friendly IP input fields (inputmode="decimal") for easy smartphone setup. Network & WiFi Manager:Captive Portal AP (WeatherStation_Setup) for initial setup. Full DHCP & Static IP configuration support (optimized for FRITZ!Box Mesh networks). Soft-restart clean boot sequence ensuring stable network stack binding. Home Assistant Integration:Native MQTT Auto-Discovery (homeassistant/sensor/...). Automatic entity creation in Home Assistant without manual YAML editing. Backup & Restore: Single-click JSON export/import including full network, sensor, and MQTT configurations. Hardware Safety & Diagnostics: 10-second hold on FLASH button (GPIO 0) for NVS memory wipe / factory reset. IMPORTANT: Please print all parts it in PETG, this project will be under the sun ray every days. The rain meter is a modified version of this project (SS4H-RG Rain Gauge Project by SmartSolutions4Home) and I thank you very much for your excellent work, in order to increase its sensitivity by increasing the rain collection surface and adding space for 2 magnets to avoid missing readings.   For the firmware and detailed info please refer to GitHub repos https://github.com/byte4geek/weatherstation
