Garage Smart Kit — ESP32 Garage Door Opener
Open your garage door from Home Assistant — no cloud required. A complete ESP32-C3 + relay kit that wires to your garage opener in about 10 minutes and talks to Home Assistant over local Wi-Fi.
What is in the box
- ESP32-C3 SuperMini development board (pre-flashed with ESPHome config)
- 2-Channel 5V relay module
- HC-SR04 ultrasonic sensor (car-present detection)
- Jumper wires (40pcs) + USB-C cable
- Step-by-step build guide + free online simulator demo
How it works
- Unbox & check the BOM — the ESP32-C3 comes pre-flashed, do not factory-reset it.
- Wire the relay: GPIO4 → Relay IN, 5V → VCC, GND → GND; relay output in parallel with your wall button.
- Mount the enclosure near your opener (magnets or screws included).
- Home Assistant auto-discovers the ESPHome node — click Configure, done.

Plant Pal Kit — ESP32 Smart Watering
Keep your plants alive without thinking about it. An ESP32-C3 reads a capacitive soil-moisture sensor every 15 minutes and drives a mini pump when soil drops below 30% — all logged to Home Assistant over Wi-Fi.
What is in the box
- ESP32-C3 SuperMini development board (pre-flashed)
- Capacitive soil moisture sensor v1.2 (corrosion-resistant)
- 2-Channel 5V relay module (pump drive)
- Breadboard + jumper wires + USB-C cable
- Step-by-step build guide + free online simulator demo
How it works
- Unbox & check the BOM — ESP32-C3 arrives pre-flashed.
- Insert the sensor into soil to the marked line; wire A0 → sensor OUT, GPIO5 → pump relay IN.
- Calibrate once: dry soil = 0%, fully wet = 100%.
- Home Assistant auto-discovers moisture sensor + pump switch.
