Shelly Plus 1 PM

The Shelly Plus 1 PM is an enhanced WiFi smart relay with integrated power monitoring in the compact Plus series form factor. This behind-the-switch relay controls loads up to 16A while tracking power consumption, energy usage, and voltage in real-time. The ESP32-based design offers improved processing power and connectivity reliability over previous generations.

The device supports Bluetooth for initial setup and WiFi for ongoing operation, with local API access for hub-free control and MQTT for advanced integrations. The scripting engine allows custom automations to run directly on the device without cloud or hub dependency. Power monitoring enables sophisticated automations based on device state detection.

Home Assistant users particularly appreciate the local API integration and comprehensive energy data. Amazon Alexa and Google Home support through Shelly Cloud provides voice control for mainstream smart home users. The Plus series represents Shelly's current generation, balancing powerful features with the compact, retrofit-friendly design philosophy that defines the brand.
