Shelly Ogemray 25A Smart Relay Switch

The Shelly Ogemray 25A Smart Relay Switch is a heavy-duty relay designed to automate and control high-power appliances and electrical circuits. Built for demanding loads, it connects directly over WiFi or Bluetooth without the need for an additional hub, making it suitable for both residential and light-commercial installations. With strong terminals, robust construction and wall-mounting hardware included, it is engineered for reliable long-term operation.

Supporting loads up to 25 A (approximately 6000 W), the relay is ideal for controlling water heaters, boilers, HVAC equipment, pumps and other high-consumption appliances. Real-time energy and power metering is built in, providing accurate consumption data to help users optimise energy usage. The relay also supports advanced automation functions, allowing integration with schedules, triggers and complex smart-home workflows.

Key Features

• High-load switching (25 A / 6000 W): Capable of controlling heavy appliances and large electrical loads beyond the capabilities of standard smart relays.
• Built-in power metering: Provides real-time energy and power consumption data for the connected load.
• WiFi and Bluetooth connectivity: Connects directly to your network without requiring an additional hub.
• Advanced automation support: Timers, schedules, scripting, MQTT, webhooks, virtual components and more for highly flexible automation setups.
• Durable, wall-mountable form factor: Strong terminals and supplied mounting bracket enable secure installation even in tight spaces.
• Over-current and over-voltage protection: Safety features protect both the relay and connected appliances under abnormal conditions.
