About this product

The Shelly Pro 4PM is a four-channel smart relay built for installation in the electrical panel on a 53 mm wide DIN rail. Each of the four outputs switches up to 16 A, while the device total is 40 A, letting you manage lighting, a water heater and socket groups from a single module.<br><br>It measures AC voltage and current on every channel and includes an internal temperature sensor, giving real consumption data for each circuit. The color display with three front buttons shows output status right in the panel, with no app needed.<br><br>Triple connectivity, Wi-Fi 802.11 b/g/n, Bluetooth 4.2 and an RJ45 Ethernet port, delivers stable local control and integration with Home Assistant, Google Home and Amazon Alexa. It runs on 110-240 V, draws under 4 W and includes over-temperature, over-voltage, over-current and over-power protection.

Where it works

Use cases

In a Chisinau flat the electrician fits the Shelly Pro 4PM into the breaker panel and remotely controls lighting, the water heater and two sockets.

Four circuits managed from a single DIN-rail module with per-channel consumption metering.

A homeowner in Ialoveni checks in the app which circuit draws the most and switches off idle loads.

The AC ammeter and voltmeter report the real power of each channel to help manage the electricity bill.

Inside the metal panel of a downtown Chisinau office the installer uses the network cable for uninterrupted communication.

The RJ45 port gives stable local control even where Wi-Fi is weak inside a metal panel.

Analytics

See consumption — save on bills

Real-time consumption tracking via the eWeLink app. Daily, weekly and monthly history helps identify the most energy-hungry devices.
