Скачать или смотреть Custom HVAC Control System – ESP32-S3 + Home Assistant Integration (Test Bench Demo)

This video demonstrates the complete functionality of your custom HVAC control system, fully integrated with Home Assistant and powered by ESPHome running on an ESP32-S3.

This setup replicates the logic of physical HVAC control panels while offering a modern, responsive digital interface. Every input — whether physical or virtual — is synchronized in real time, with clear interlocks, mode-based behaviors, and visual feedback.

🔧 *Features included in this build:*
Control via both Home Assistant dashboard and physical push buttons
Real-time relay state visualization and LED indicators
Exclusive button behavior to prevent relay conflicts
Mode-based operation: HVAC (Cool/Fan/Heat), Cooler, Manual Override
Safe handling of Dump Pump logic with cycle timers and lockouts

📦 *Hardware Summary:*
ESP32-S3 DevKitC-1
7x opto-isolated 5V relay modules with 1N4007 flyback diodes across relay coils
8x momentary push buttons
7x status LEDs with 330Ω resistors
5V/2A power supply, mounted on a breadboard for testing

🧪 *Testing Modes Demonstrated:*
Full HVAC logic (Cool, Fan, Heat with interlocks)
Cooler Mode: water pump, blower (low/high), dump cycle
Manual Override Mode: direct physical control bypassing automation logic

💡 This testbench was designed to validate logic, electrical behavior, and user interaction before final deployment. All timing, input mappings, and visual states are fully customizable and can be adapted to your final hardware enclosure.
