Shelly 1PM Mini Gen4 smart relay for lighting

Shelly 1PM Mini Gen4 smart relay for lighting

The Shelly 1PM Mini Gen4 is the new generation of Shelly’s smart relay and the smallest wireless smart home device of its kind in the world. It controls a lighting circuit or a wide variety of loads up to 8 A.

Installed behind a wall switch, it turns that switch into a smart switch you can control remotely and by voice. It tracks how long a light was on and what it cost, supports unlimited on and off timers, and alerts you to a short circuit or fault.

Shelly is small enough to fit behind a standard switch, inside a light fixture or in a junction box. The switch keeps working as usual, while Shelly adds a full range of smart home capabilities, making it just as useful at home and in the office as in industrial settings.

It can also export power consumption data to an Excel file.

The Gen4 model adds Bluetooth, a more powerful processor, Matter and Zigbee support and advanced software options for developers.

Who it’s for

A tiny smart relay with power metering, for lighting and small circuits up to 8 A in crowded wall boxes. The app shows how much the circuit uses and what it costs. For a water heater, an air conditioner or another heavy load, use the Shelly 1PM Gen4. All models are in the smart relay category.

Before you install

  • Requires a neutral wire in the wall box.
  • Up to 8 A.
  • Fits in a standard 55 mm wall box behind the switch, and your existing switch keeps working.
  • Wi-Fi, Zigbee and Matter.

FAQ

Is it suitable for a water heater?

No. A water heater draws more than 8 A. For a water heater, use the Shelly 1PM Gen4, rated up to 16 A.

How is it different from the 1 Mini Gen4?

The 1PM Mini also measures power consumption. The 1 Mini is a dry-contact relay with no metering.

Can I get an alert when a bulb burns out?

Yes. The app detects the drop in consumption, and a scene sends you a notification.

מותקן בחדר השינה ונשלט על ידי Home Assistant.
התקנה פשוטה ועובד מעולה, הקושי היחיד היה לגלות שצריך להגדיר את סוג המתג.
