Description

The Shelly Ogemray is built for handling significantly heavier loads than standard Shelly devices such as the Mini 1PM. While the Mini range is limited to around 8A, the Ogemray supports up to 25A and 6000W, making it suitable not only for domestic appliances but also for industrial equipment and other high‑demand machinery.

At its core is Shelly’s in‑house ShellyX chip, giving the Ogemray native compatibility across the wider Shelly ecosystem without the need for a hub or special wiring. Like other Shelly products, it communicates over both Wi‑Fi and Bluetooth and includes precise power‑monitoring capabilities, allowing users to track consumption of whatever equipment it controls.

For more advanced integrations, the Ogemray offers extensive protocol support including scripts, webhooks, MQTT, WebSocket, HTTPS, UDP, TLS and custom certificates. It can be managed through the free Shelly app or integrated with numerous third‑party smart‑home platforms, ecosystems and voice assistants, making it highly flexible for both simple and complex automation setups.
