Shelly Pro Dimmer 1PM Smart DIN Rail Switch

The Shelly Pro Dimmer 1PM sets an advanced industrial standard for centralized single-channel mains voltage (230V AC) lighting control and energy tracking across modern smart environments. Engineered specifically for secure physical integration on standard DIN rails inside circuit breaker panels, this micro-module features a high-capacity output topology designed to handle complete lighting zones seamlessly. The integrated auto-calibration engine screens the connected lighting array to apply precise leading or trailing-edge phase control, eliminating common issues like bulb buzzing or low-end strobe flicker on dimmable LED channels.

The defining operational milestone of the professional line is the native physical LAN (Ethernet) port. This wired pipeline provides absolute network uptime and complete immunity against radio frequency interference, making it an essential component for high-end automated residences, commercial spaces, and hotels where zero latency is required. The "1PM" designation denotes an onboard power monitoring engine that captures individual real-time electricity statistics. System integrators can easily build precise cost-saving schedules, custom fade-in/fade-out transition rates, and automated timers tied to local sunrise or sunset triggers.

Housed inside a premium flame-retardant (V-0) enclosure, the module continuously monitors internal operational parameters to automatically trip connected lines within milliseconds if overtemperature, overvoltage, or overload events occur. Driven by raw processing speed, it executes local JavaScript scripts and schedules completely independent of cloud server infrastructure. Delivering native out-of-the-box compatibility with Home Assistant, industrial MQTT bridges, and Webhooks, the Shelly Pro Dimmer 1PM is a dependable choice for infrastructure upgrades.
