Powerful Automation for Heavy-Duty Appliances
The Ogemray 25A is designed to handle more demanding applications than typical smart relays. While standard Shelly devices like the Mini 1PM can manage up to 8A, the Ogemray handles up to 25A, making it suitable for heavy-duty residential and light industrial use. Control and automate water heaters, water pumps, fans, lights, HVAC systems, and other high-power devices remotely from anywhere via the Shelly app or your preferred smart home platform. Set custom schedules to optimise energy use, or trigger actions based on time of day, sensor inputs, or other connected Shelly devices.
Precision Energy Monitoring
Keep a close eye on your energy consumption with the Ogemray's built-in power metering. Monitor real-time power draw, voltage, and cumulative energy use for connected appliances. The relay tracks usage patterns and helps you identify opportunities to reduce waste and lower your electricity bills. Perfect for Australian households and businesses looking to improve energy efficiency and meet sustainability goals.
Seamless Smart Home Integration
Powered by Shelly's proprietary ShellyX chip, the Ogemray 25A is natively compatible with the entire Shelly ecosystem and integrates effortlessly with major smart home platforms including Google Home, Amazon Alexa, Apple HomeKit (via third-party bridges), Samsung SmartThings, Home Assistant, Hubitat, and over 200 others. Advanced users will appreciate support for MQTT, WebSocket, HTTPS, UDP, TLS, scripting (mJS), webhooks, custom certificates, and KNXnet/IP communication. All primary functions operate 100% locally, so your automation continues to work even if your internet connection drops.
Wi-Fi & Bluetooth Connectivity
The Ogemray connects to your 2.4 GHz Wi-Fi network (802.11 b/g/n) with a range of up to 50m outdoors and 30m indoors. Bluetooth 4.2 allows for local setup, direct communication with Shelly BLU battery devices, and backup control. The relay features a potential-free input for connecting physical switches and supports flexible configuration for classic toggle or push-button switches.
Robust Construction & Safety Features
Built for reliability, the Ogemray 25A includes overvoltage protection with auto recovery, overpower protection, and an internal temperature sensor to ensure safe, long-term operation. The device is rated for 110-240V AC ±10%, 50/60Hz and consumes less than 1.2W when idle. Large screw terminals accommodate cables from 0.2 to 4 mm² (24 to 11 AWG), making installation straightforward and secure. The compact white plastic housing measures just 51.4 × 60 × 26.5 mm and weighs 82 g, ensuring it fits easily into tight spaces.
Flexible Installation Options
Install the Ogemray 25A in standard electrical wall boxes, control panels, fuse boxes, or directly on the wall using the included mounting bracket and anchors. No rewiring is required - simply wire it in line with your existing appliance. The device supports one input with flexible configuration for controlling the relay output via a connected switch.
