ESPHome Professional Packages — C++ alarm engine + Improv BLE + full telemetry in 3 files

[RamiLEK001]

Hi ESPHome devs and contributors 👋

I wanted to share a modular package system I built on top of ESPHome
that might be useful as a reference or starting point for others.

What it includes

lib-wifi_conectividad.yaml

• Improv BLE provisioning (no SSID pre-config needed)
• Fallback AP with 15-min smart timer
• API Watchdog: auto-reboot if HA is unreachable for 5 min
• Full WiFi telemetry: dBm → %, MAC, BSSID, IP

lib-estados_alarmas.yaml

• C++ alarm engine running every 29s
• 4 severity levels: Nominal / Minor / Moderate / Critical
• Thresholds via substitutions (RAM, temp, loop time, WiFi signal)
• Native HA Push notifications on level ≥ 2
• LED status indicator tied to alarm state

configuracion_base.yaml

• Master template with hardware profiles (ESP32, C3, WROVER, ESP8266)
• Version tracking via project: block
• Requires ESPHome ≥ 2026.2.1
