DIN-rail stair lighting controller for Home Assistant and ESPHome. Thirty-two low-side MOSFET channels rated 1.5 A each drive one 12 or 24 V LED step per channel, each individually dimmable with 8-bit brightness on Modbus holding registers 400-431, and two presence-sensor inputs detect direction of travel. Modbus RTU slave on RS-485, configured over USB-C from a browser. The step sequence is written on the controller.

DIN-rail RGB and tunable white LED controller for Home Assistant and ESPHome. Five low-side PWM channels - red, green, blue, cool white and warm white - for 12 or 24 V common-anode strip, with 12-bit gamma-corrected dimming exposed on Modbus as both 0-255 and 0-4095. One dry-contact relay rated 3 A at 250 V AC switches the strip supply, and two IEC 61131-2 compliant 24 V inputs take wall buttons. Modbus RTU slave on RS-485.

DIN-rail phase-cut AC dimmer for Home Assistant and ESPHome. Two independent MOSFET channels with leading or trailing edge selectable per channel, and four IEC 61131-2 compliant 24 V inputs for wall buttons with short, long, double and short-then-long press logic. Modbus RTU slave on RS-485, configured over USB-C from a browser. Local dimming continues when the controller is unavailable. See the datasheet for load ratings and derating.
