Ultra-compact Wi-Fi energy meter

The Shelly PM Mini Gen3 is a single-channel 16 A Wi-Fi energy meter designed for precise power monitoring in tight spaces. It connects to lights or electrical appliances in under 10 minutes and tracks consumption from anywhere via the Shelly Smart Control app. The upgraded ESP Shelly chip with 8 MB memory improves responsiveness and also enables Bluetooth gateway and Wi-Fi range extender functions. This two-pack provides monitoring for two separate circuits.

Monitoring-only device for retrofit installs

This meter suits homeowners and installers who need accurate energy data without replacing existing switches or sockets. Its 35 % smaller form factor fits behind standard wall hardware where larger relays cannot. Buyers who require on-board switching or load control should look at relay-equipped alternatives instead.

Single-channel 16 A current rating

The 16 A maximum current defines the safe monitoring limit for each connected circuit. Exceeding this rating risks device damage and inaccurate readings, so verify the load draw of every appliance before installation.

Questions about this item

Does the 16 A meter itself contain any moving parts or batteries that will need replacement later?

The meter has no internal relay or moving parts and no user-replaceable battery, so no scheduled component swaps are required.

What stops the 16 A channel from logging data continuously during a long monitoring session?

Internal flash memory and the cloud service set the practical limit; the device keeps measuring as long as it has power and Wi-Fi connectivity.

How much heat or noise does the meter add when it sits behind a switch running all day?

It draws only milliwatts for its own electronics, produces no audible noise, and stays at ambient temperature inside the wall box.
