Smart Home Functionalities with HomeMaster Devices

At HomeMaster, we deliver modular, open-source automation systems designed for seamless integration with ESPHome and Home Assistant. Our solutions are engineered for flexibility, privacy, and full local control—empowering both residential and commercial environments. With a growing ecosystem of smart devices, here’s how you can take control of your space:

Lighting Control ​

Automate and personalize lighting throughout your home or office. With our RGB-CCT Modules, Dimmer Modules, Relay modules and Stair LED Controller Modules, you’ll have advanced options for ambient lighting, dynamic stair effects, and dimmable circuits—integrated with sensors, switches, or scenes.

Ventilation

Use humidity sensors and presence detection to manage ventilation fans or motorized windows. Our relay and sensor modules allow smart ventilation strategies that improve air quality and reduce energy waste.


Heating

Take full control of heating systems with our ESP32-based MiniPLC, MicroPLC, and OpenTherm Gateway. Smart scheduling, zone-based control, and weather-aware automations keep your space efficient and comfortable—perfect for radiators, underfloor heating, or HVAC systems.

Energy Management

Monitor and optimize your energy use with the upcoming Energy Counter Module, featuring voltage and current inputs, a relay, and PWM output. Combine it with other modules for dynamic load balancing, peak shaving, or energy reporting—integrated right into your Home Assistant dashboard.


Alarm & Security

Our Alarms Module with 17 input channels and relays enables reliable integration of traditional security sensors—like motion detectors, contact sensors, and sirens. Trigger automations, receive alerts, and ensure safety, all without relying on the cloud.  

Access Control

Control electric gates, door locks, or garage doors using switches. Relay modules paired with presence sensors or custom logic allow secure and flexible access systems for homes and offices alike.


Garden Irrigation

Automate your irrigation with time-based or sensor-driven logic. Use our relay modules or  analog I/O modules to control irrigation valves, monitor soil moisture, and even integrate water-saving algorithms—all directly via ESPHome.  

Water Management & Leak Detection

Protect your home from water damage with our upcoming Water Leak Detector Module, featuring 5 inputs for leak sensors and water meters, and 2 relays to control electric shutoff valves. Prevent flooding, monitor usage, and react instantly to issues.
