This Instructable shows how to build low-cost Arduino-based wireless sensor nodes integrated with OpenHAB on a Raspberry Pi (or PC) to provide timely alerts (email/audio) and mobile status for home monitoring (dog barks, washer/dryer, door/window, temperature, gas/smoke, water leaks, garage door, GPS dog tracker, etc.). It uses RFM69HW transceivers for long range, MQTT (Mosquitto), and examples for battery and mains-powered designs, plus wiring, sketches, and OpenHAB configurations. The project emphasizes flexibility, reliability, and aesthetic presentation of sensor data.
