If you need clean, flicker-free analog dimming for a handful of circuits — LED drivers, HVAC actuators, motor speed controllers — the KinCony DM4 gives you exactly that in a compact DIN rail package. It delivers four independent 0-10V DC output channels driven by the ESP32-S3, with Wi-Fi, Ethernet, RS485, and Bluetooth all built in. At 114 x 83 x 59 mm it is one of the smallest controllers in the DM series, making it a natural fit for smaller panels or installations where channel count is modest but reliability and connectivity still matter.

Why You'll Love This Controller

✔ Clean Analog Output
The 0-10V outputs are genuinely smooth — no PWM artifacts, no flicker. If you are dimming LED drivers or controlling actuators that are sensitive to signal quality, this matters.

✔ Precise Sensing
The ADS1115 16-bit ADC gives you sensor readings you can actually trust, including direct support for 4-20mA industrial current loop sensors without any external conversion circuitry.

✔ Firmware Freedom
Use KCS v3 for zero-config Home Assistant integration via MQTT, ESPHome for YAML-based customization, Tasmota for open-source flexibility, or write your own code in Arduino IDE, MicroPython, or ESP-IDF. Your project, your rules.

✔ Smart Platform Ready
Works with Home Assistant, Tuya app, Apple HomeKit (Siri), Google Home, Alexa, and Loxone Miniserver right out of the box with KCS v3 firmware.

✔ Right-Sized for Smaller Installations
At only 114 x 83 x 59 mm, the DM4 fits in panels where a larger board would be overkill. Four channels is often exactly what a room or zone needs.

Among other outstanding features are the following:

• Multi-Network Connectivity: Wi-Fi and 100Mbps Ethernet (IPv4/IPv6) are both available simultaneously, with Bluetooth and USB-C rounding out the connection options. RS485 adds wired serial communication for Modbus devices.
• OLED Status Display: The SSD1306 OLED screen shows the current Wi-Fi IP address, Ethernet IP address, and Tuya cloud connection status — handy at a glance during commissioning or troubleshooting.
• Multi-Protocol Support: Works with HTTP, MQTT, TCP, RS485 Modbus, and the Tuya app. KCS v3 firmware also supports local IFTTT-style automation that runs entirely without internet access.
• Apple HomeKit and Loxone Support: KCS v3 firmware includes Apple HomeKit support for Siri voice control, and native integration with Loxone Miniserver for users already in that ecosystem.
• Free GPIO Pins: Four additional GPIO pins connect directly to the ESP32-S3 (no pull-up resistors on PCB), giving you raw access for custom sensors, LEDs, or other peripherals.
• Cloud Service: Customers purchasing from the official store receive two years of free KinCony cloud access, enabling remote monitoring and control from any web browser without setting up a VPN or port forwarding.
