01 — Deployed devices
In the walls, working.
RATGDO - Garage Door Controller
Deployed / Intermediate
ESP32-based controller for Security+ 2.0 garage door opener. Provides open/close control, position sensing, and obstruction detection via Home Assistant.
Gate-Alarm Sensor
Deployed / Beginner
Dog containment gate monitor with magnetic reed sensors. Detects gate position and alerts when left open. Integrated with HA for notifications.
Electric Fence Monitor
Deployed / Intermediate
Perimeter fence monitoring system tracking fence status and zone alerts. Provides dashboard visibility and automated notifications.
Vacuum Water Shutoff Relay
Deployed / Beginner
Automated water shutoff valve controlled via ESP32 relay. Triggers on leak sensor detection to prevent water damage.
02 — Case study
Whole-home IoT integration.
The challenge
Create a unified smart home system that monitors garage, gates, fencing, and water systems — all controllable via Home Assistant with automated safety responses.
The solution
- Deployed RATGDO for native Security+ 2.0 garage door integration
- Built magnetic sensor system for dog containment gate monitoring
- Integrated electric fence monitoring with zone-based alerts
- Designed water shutoff automation triggered by leak sensors
- Created unified HA dashboard with tablet-friendly controls
- Set up push notifications for all critical events
03 — Planned devices
On the bench next.
Presence Detection Sensors
Planned / Intermediate
mmWave radar sensors for accurate room presence detection, improving automation accuracy beyond motion sensors.
Custom Light Controllers
Planned / Beginner
ESP32-based LED strip controllers with WLED firmware for ambient lighting automation.
