Why You'll Love This Controller
✔ Fail-Safe Hardware Redundancy
Integrated manual toggle switch offer a reliable backup control method independent of software or network status, guaranteeing continuous operation and simplifying troubleshooting.
✔ Your Gateway to Every Major Smart Ecosystem
Be platform-agnostic. Use it with Home Assistant locally, integrate via Apple HomeKit, manage remotely with Tuya Smart, or leverage our powerful KCS v3 firmware with multi-protocol support for ultimate flexibility.
✔ Unlock Limitless Customization
Go beyond pre-built apps. The open programming platform (Arduino IDE, MicroPython, ESP-IDF) puts you in full control, allowing you to create tailored logic, unique automation sequences, and specialized data handling.
✔ Dramatically Simplify Your Control Panel
Replace a tangle of separate timers, relay modules, and network gateways with one intelligent, unified device. Save space, reduce wiring costs, and streamline troubleshooting.
Among other outstanding features are the following:
-
DIN Rail Ready Design: Mounts effortlessly in any standard electrical cabinet for a professional, organized installation.
-
Precision Sensing Suite: Integrated 16-bit ADC provides four high-accuracy analog inputs (0-5V & 4-20mA) for monitoring sensors and processes.
-
Network for Every Scenario: Dual connectivity with Wi-Fi and 100Mbps Ethernet ensures reliable communication, whether for local control or remote cloud access.
-
Standalone Time Intelligence: Built-in high-precision RTC (with battery backup) keeps perfect time and executes scheduled tasks, even without an internet connection.
-
At-a-Glance Status: On-board OLED display shows live IP addresses, connections, and system status for instant diagnostics.
