Meet the KinCony B8: a powerful, ready-to-command control unit designed specifically for your high-power automation projects. Built around the powerful ESP32-S3, this smart relay controller doesn’t just process signals-it physically dominates your real-world machinery. With eight heavy-duty relays capable of switching up to 250V AC, it’s the ultimate upgrade for industrial control cabinets, commercial systems, and demanding DIY setups, bridging modern IoT intelligence with legacy high-power equipment seamlessly.

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.

✔ Command High Power with Zero Extra Hardware
Forget complicated driver circuits! These built-in industrial relays let you switch serious AC/DC loads directly-perfect for automating workshops, farm equipment, or large lighting setups right out of the box.

✔ 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:

• Industrial-Grade Relay Command: Eight robust relays handle up to AC250V/7A each, letting you directly control motors, pumps, lights, and solenoids with confidence.
• 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.
