HomeMaster – MicroPLC, MiniPLC, Relays, RGB Modules & More

PLC:

HomeMaster MiniPLC – Complete Standalone ESP32 PLC

Industrial-grade DIN-rail controller with comprehensive onboard I/O: 6 relays, 4 digital inputs, 4 analog inputs, temperature sensors, and display. Built-in AC/DC power supply (85-265V AC or 24V DC) for standalone operation. Optional expansion via RS-485 Modbus. Pre-installed ESPHome for native Home Assistant integration. Ideal for complete automation solutions without external modules.

HomeMaster MicroPLC – Modular System Controller

Compact ESP32-C3 DIN-rail controller designed as the central hub for modular expansion. Minimal onboard I/O keeps costs low while controlling unlimited modules via RS-485 Modbus. Requires 24V DC external power supply (shared across all modules). Perfect for building custom automation solutions by adding only the specific I/O modules needed. ESPHome pre-installed for Home Assistant.
