I will build esp32 iot systems with mqtt dashboards home assistant

Need a real IoT system, not just a breadboard demo?

I will build ESP32-based IoT firmware and system integration for sensors, actuators, MQTT communication, Home Assistant, Node-RED, Grafana, and cloud/back-end dashboards.

I can help with:

ESP32 / STM32 / Raspberry Pi IoT firmware

Sensor reading, calibration, and actuator control

MQTT publish/subscribe communication

Wi-Fi, BLE, LoRaWAN, Modbus/RS-485 integration

Home Assistant, ESPHome, Node-RED, or Grafana dashboards

Data logging, alerts, automation rules, and API integration

Wiring guidance, BOM, setup guide, and test plan

Common projects:

ESP32 sensor monitoring system

Air quality or energy monitoring device

LoRaWAN GPS tracker with ChirpStack

Industrial Modbus-to-MQTT gateway

Home Assistant automation

Raspberry Pi IoT gateway or dashboard

You will receive clean firmware, clear architecture, source code, and documentation that can be maintained later.

Please message me before ordering so I can review your hardware, features, and expected deliverables.
