Short description

Shelly Plus PM Mini (The Device) is a small form factor power meter. Enhanced with all the gen2 firmware flexibility, it provides professional integrators with additional options for end-customer solutions. It can work standalone in a local Wi-Fi network, or it can also be operated through cloud home automation services through MQTT, HTTP, and WebSocket. All inbound connections support TLS.

Shelly Plus PM Mini can be accessed, set up, and monitored remotely by the User, as well as the Device can access and communicate with an automation system, as long as they are in the same network infrastructure.

The Device has an embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.

⚠NOTICE! The Device does not have a built-in relay.
