Installation / Application Notes
• Ideal for large electrical panels requiring many controlled circuits.
• Supports simultaneous use of Tuya (cloud) + Home Assistant (local) via KCS firmware.
• Manual relay buttons provide direct hardware fallback without firmware.
• 1-Wire ports support DS18B20 and similar sensors.
• ESPHome makes integration with Home Assistant simple; YAML templates are available from KinCony.
• Optional SIM7600 module allows SMS control, remote switching, and GPS.
• 0–10V dimmer channels suitable for LED drivers, analog dimmers, HVAC dampers.
• All input ports use removable terminal blocks for easier wiring.
