⚡ Key Features

16A Relay + Power Metering — switch and measure geyser contactor circuits, pool pumps, lighting feeds and plug circuits from the DB board
Triple Connectivity — wired Ethernet (LAN), WiFi 2.4GHz and Bluetooth; Ethernet keeps automations running even when WiFi is flaky
Built-In Protections — overpower, overvoltage and overtemperature protection safeguard the connected load
DIN-Rail Mount — clean, professional install in the breaker box; 1 module wide
Local Control, No Hub — embedded web interface, schedules, scenes, MQTT, webhooks and Shelly Scripting

Switch Input — wire an existing wall switch or push-button for manual control alongside automations

🇿🇦 Installer Tip: Perfect for geyser control via a contactor — schedule heating around Eskom time-of-use tariffs, monitor actual consumption, and kill the circuit remotely. The LAN port means the DB board's steel enclosure can't block your connection.
