ESP32 Tesla BLE Control with Home Assistant
Turn an ESP32 into a local Tesla BLE bridge with ESPHome and Home Assistant. This project brings charging controls, vehicle data, and diagnostics into a dashboard, while keeping communication nearby. Start with the tested YAML example, check pairing and range, and protect every command that can affect the car.

Behind its geometric planter shell, murCO uses an ESP32-based controller and SCD40 sensor to send local CO₂, temperature, and humidity readings to Home Assistant. LEDs, optional speech, and Bluetooth proxy features make ventilation information useful without depending on a dashboard. The open-source repository and project documentation provide implementation details.

Tiny points of colored light can feel surprisingly alive when they move, fade, and sparkle independently. This project pairs an ESP32-based Adafruit board with addressable LEDs and CircuitPython, giving makers a hands-on way to build an animated display, then adjust its colors, timing, brightness, and physical form.

At 2.02 volts, a battery pack exposed the gap between firmware’s “protected” message and real electrical safety. This ESP-NOW RC car pairs an ESP32 controller with an ESP8266 vehicle board, then adds packet checks, acknowledgements, failsafes, pairing, and hard-won debugging lessons from actual hardware faults.

Three useful readings come from one fingertip module: heart rate, SpO2, and temperature. This ESP32 project covers the wiring, Arduino sketches, and optical sensing behind each value. It is a practical introduction to I2C and physiological data, but the results are experimental and not suitable for medical diagnosis.

Pressure-cooker whistles are easy to miss when the kitchen gets busy. This ESP32 project uses a MAX4466 microphone to count sound events, then sends a WhatsApp message through CircuitDigest Cloud when the selected count is reached. It needs careful calibration, reliable Wi-Fi, and continued supervision around the cooker.

On a desk or wall, SonosESP turns a 4-inch or 7-inch touchscreen and ESP32-P4 into a dedicated music remote. It browses libraries, controls speakers across rooms, shows album art and lyrics, displays weather and clocks, and receives firmware updates without being removed from its mounting.
