DIN-rail digital input module for Home Assistant and ESPHome. Seventeen opto-isolated inputs with 5300 VRMS isolation for door and window contacts, PIR detectors, leak sensors and tamper loops, plus three SPDT relays rated 3 A at 250 V AC. Isolated 5 V and 12 V rails power the sensor loops from the module. Modbus RTU slave on RS-485. Zone grouping and latch-until-acknowledge run on the module. Not a certified intruder-alarm system.

DIN-rail water leak detection and metering module for Home Assistant and ESPHome. Five identical universal isolated inputs, each configurable as a leak sensor, a soil-moisture probe or a pulse water meter, plus a 1-Wire bus for temperature probes and two SPDT relays rated 3 A at 250 V AC for shut-off valve control. Modbus RTU slave on RS-485. Heat-energy figures are indicative for monitoring and are not approved for billing.
