The Shelly 1PM Gen3 (4-pack) holds four identical smart relays in one box, made for anyone equipping several circuits at once: a whole flat, a renovation project or an installer job. Each module precisely measures voltage and current, so you see the real consumption of every circuit in the Shelly app.<br><br>The module fits behind a switch or inside a wall box and switches loads up to 16 A at 240 V~. It has an input for a classic switch, supports scenes, schedules and scripts, while overheating, overvoltage, overcurrent and overpower protections keep the wiring safe.<br><br>With built-in 2.4GHz Wi-Fi and Bluetooth for quick setup, each relay is controlled from your phone and integrates with Google Home, Amazon Alexa, SmartThings, Home Assistant and MQTT. The 4-pack lowers the per-unit cost and simplifies buying for a complete project.
