About this Gig

Develop production-ready ESP32 firmware fully controllable via the Home Assistant Companion app. I integrate Matter (over Thread/WiFi), MQTT auto-discovery, BLE commissioning, and ultra-low-power design.


Technologies & Protocols:

- ESP32 / ESP8266 (Arduino Core / ESP-IDF)

- Matter (Thread/WiFi), MQTT, BLE GATT

- FreeRTOS, Deep Sleep, Light Sleep, OTA

- Home Assistant Auto-discovery & Control

- Sensor Integration (I2C, SPI, UART)


Integration Paths:

- Matter: On-chip clusters for lights/sensors, QR code commissioning. Works with HA, Apple, Google, Alexa.

- MQTT: Publishes HA discovery JSON for automatic entity creation. Instant app control.


Low Power:

- Thread Sleepy End Device (SED) & Deep Sleep support.

- Standby current as low as ~10µA for battery devices.


Deliverables:

Clean, well-commented source code, wiring diagram, commissioning guide, and power report.


Let's turn your IoT idea into reality! Please message me before ordering to discuss your transport (Matter-Thread/WiFi or MQTT) and power source.
