Shelly 1PM Gen3 is a compact smart switching module with energy metering and up to 16 A load. It offers remote control over Wi‑Fi/Bluetooth, works without a hub, and is compatible with Alexa/Google, KNXnet/IP and MQTT. With advanced security, schedules, and scripts, you can easily automate lights, heating, and appliances and gain a clear view of energy usage.
Transform your home or office into an intelligent, efficient space. Shelly 1PM Gen3 combines a powerful 16 A relay with precise energy measurement (voltage/current/power) and stable connectivity via Wi‑Fi and Bluetooth. It only needs your existing network — no central hub — and works with the Shelly Smart Control app, voice assistants Amazon Alexa and Google Home, as well as KNXnet/IP and MQTT protocols. The built‑in Bluetooth gateway and Wi‑Fi range extender ensure reliable control throughout the premises.
The new ESP‑Shelly‑C38F processor with 8 MB flash memory delivers quick response, secure encryption, and support for scripts and webhooks for advanced automations. Create scenes, schedules, and link Shelly 1PM Gen3 with other devices. The internal temperature sensor protects the module against overload, and together with the Shelly Plus Add‑on and the DS18B20 sensor you can monitor, for example, the water temperature in a boiler. Ideal for lighting, underfloor heating, retrofitting older appliances, and irrigation control.
