Shelly Plus i4

Overview

Shelly Plus i4 converts up to four conventional switches, push buttons or other dry-contact controls into smart-home inputs. It does not switch the connected loads itself; instead, it detects input events and uses them to control other Shelly devices, scenes or third-party automations.

Each input can respond to different actions, making the Plus i4 a practical way to keep familiar wall controls while adding far more flexibility behind them. A multi-button wall plate can operate lights, blinds, heating scenes or whole-home routines without running separate control wiring to every load.
