On the Road to Matter
Each Gen3 device is engineered to be upgradable to Matter. The doubled memory, compared to Plus series, guarantees a smooth update process, paving the way for new smart capabilities and integrations. *Dependent on the extent of Matter's functionalities support.

More Memory, More Power
The Gen3 series ensures the quality and reliability of our devices by using our own powerful Shelly chip. Boasting 8MB of memory, this dramatically improves device performance and efficiency. This significant increase in memory not only guarantees smoother and faster operation but also equips the Gen3 series for the introduction of new capabilities.

Unified Control with Virtual Components
The Gen3 Series introduces "virtual components, transforming how you manage and control 3rd party devices. Within the Shelly Smart Control app, you can now create virtual devices, integrating non-Shelly products into a unified control system. This feature provides streamlined control of all your smart devices, regardless of brand, from a single interface.

Preventative monitoring
When an electrical appliance is damaged, it doesn't simply stop working. Usually, it increases the amount of energy used in an attempt to compensate for its operational capacity. Since there is no visible difference in its performance, it might take months before you can identify a problem, leading to inefficiency and wasted energy. Shelly Plus PM Mini Gen 3 will fit anywhere you need it to and can immediately report the increase in energy consumption, saving you additional expenses on repairs or equipment replacement.

Power consumption analysis for cost optimization
All connected electrical appliances we don't use during the night or forgotten switched-on lights generate unnecessary energy. Shelly Plus PM Mini Gen3's smart energy metering will help you identify and eliminate any redundant energy consumption from each connected appliance around your home or facility. Together with smart scenes, you can use Shelly Plus PM Mini Gen3's data to set off scenarios, such as turning off appliances during a spike to protect them or during the night to save energy.
