ESP32 Elderly Care Alert Kit
Elderly Care Movement Alert System with ESP32 and Home Assistant Native API - No MQTT Broker
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a compact, always-on monitoring unit that watches over an elderly family member by tracking room temperature and motion. The ESP32 talks directly to Home Assistant using its native API, creating live sensor entities and a relay you can trigger remotely - all without a separate MQTT broker or cloud dependency. This kit gives you everything to assemble a caregiver alert system that fits inside a clean enclosure, complete with an OLED display for at-a-glance readings.
What You'll Build
You'll solder together a permanent prototype with an ESP32 board, DHT22 humidity sensor, PIR motion detector, OLED screen, and a four-channel relay module powered by a stable buck converter. Once flashed with ESPHome's native API config, temperature, humidity, motion state, and relay control appear instantly as entities in Home Assistant. Use them to trigger phone notifications if no movement is detected for a set interval or if room conditions go beyond safe limits.
What You'll Learn
- Configure ESPHome's native API to bypass MQTT and create real-time sensor entities in Home Assistant
- Interface DHT22, HC-SR501 PIR, and a 0.96-inch OLED on a single ESP32 while managing I�C and GPIO conflicts
- Write Home Assistant automations that check motion timeouts and temperature thresholds for caregiver alerts
- Design a low-noise 5V supply with an LM2596 buck converter, protection diodes, and decoupling capacitors for years of reliable operation

Who This Kit Is For
B.Tech ECE/EEE students building IoT solutions for elderly care will find here a ready reference for ESPHome native API implementation. Smart India Hackathon teams aiming for caregiver alert prototypes can skip MQTT complexity and go directly on-board. Home automation enthusiasts who want a local, cloud-free monitoring node for a senior family member will appreciate the zero-middleware design and the ready-to-solder parts list.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code inside the box to chat with the AI companion trained on this kit's schematic and code. It walks you through each connection and YAML block. If you need a human touch, reach out via WhatsApp-we reply within a few hours.
Will this system work without an internet connection?
Yes. ESPHome native API runs entirely on your local Wi-Fi network. Home Assistant discovers the ESP32 instantly, and all sensor data stays within your home. No cloud, no MQTT broker required.
Can I add more sensors later, like a door contact or a buzzer?
Absolutely. The four-channel relay and extra GPIOs on the ESP32 let you expand the setup. The AI companion includes hints for adding additional binary sensors to the same ESPHome config without breaking the native API integration.
Is this kit suitable for a college final-year project?
Yes. The kit demonstrates real-time IoT, edge computing without a broker, and hardware integration-topics common in B.Tech and M.Tech projects. You'll have a working prototype with a documented build process perfect for viva presentations.
Elderly Care - ESP32 native Home Assistant API exposes temperature, relay, and motion as entities without MQTT broker.
