Shelly 1PM Gen3: | Wi-Fi Switch with Energy Metering

The powerful and reliable workhorse: Shelly 1PM Gen3

The Shelly 1PM Gen3 is the evolution of a classic. This smart flush-mounted switch is the perfect choice for anyone looking for a reliable, powerful, and versatile solution to make appliances smart. With a significantly improved processor and more memory under the hood, the Gen3 architecture offers unprecedented stability and a wealth of advanced features for the demanding user.

The power of Gen3

• Powerful switching up to 16A : Switch on heavier appliances such as a boiler, electric heater or washing machine with confidence.
• Accurate Energy Metering : Get instant insight into the power consumption of connected appliances. Identify energy guzzlers, create smart automations (such as a "washing machine is finished" notification), or monitor standby power consumption.
• Enhanced Hardware : Thanks to the powerful ESP-Shelly-C38F processor and expanded memory, the 1PM Gen3 responds faster and can handle more complex tasks.
• BLE Gateway : Use your Shelly 1PM Gen3 as a bridge for your Shelly BLU devices (such as the BLU Door/Window sensor), making their data accessible to your entire smart home system.
• Bluetooth Proxy for Home Assistant : Use the 1PM Gen4 as a stable Bluetooth proxy to significantly increase the range of your other Bluetooth devices (such as thermometers and sensors) in Home Assistant.
• Wi-Fi Range Extender : Improve your network coverage. The 1PM Gen3 can boost your Wi-Fi signal for other, more distant Shelly IoT devices.
• Advanced Scripting : For experts, 1PM Gen3 offers extensive scripting capabilities. Create complex, locally running automations that operate completely independently of the cloud.

Important: Switching Inductive Loads

The Shelly 1PM Gen3 is extremely powerful, but when switching inductive loads (such as LED lighting, transformers, fans, or air conditioners), it generates an inrush current that can damage the relay. In these cases, always use an RC Snubber (sold separately) to absorb this current and ensure the lifespan of your module.

Practical application: the smart washing machine

Place the Shelly 1PM Gen3 behind your washing machine's outlet. In Home Assistant or the Shelly app, you can create a simple, yet incredibly convenient automation:

As soon as the Shelly 1PM Gen3's energy reading drops below 5 watts for more than 5 minutes, the system signals that the wash is finished. You'll receive an immediate notification on your phone. No more forgotten, stale laundry!
