Use Cases

Perfect for SMB owners

If you are a small or medium-sized business owner, you have probably struggled with energy overconsumption. Some machines and appliances are switched on all the time. With Shelly PRO EM-50, you can measure with utmost precision and reduce consumption by turning off load - water dispensers, laminating machines and lighting, during the night. The smart device can also be applied for preventative measurement by monitoring for abnormal behavior of HVAC, air compressors, refrigerator units and others.

Renewable energy ecosystem at home

If you have a photovoltaic system (PV) at home, Shelly PRO EM-50 can help you measure grid and imported energy from renewable sources. Moreover, it has configurable load control, which allows you to redirect any excess energy generated from renewable sources to electronic devices at your home and optimize your energy consumption. For example, you can use Shelly PRO EM-50 for charging your car or home appliances when your PV system provides excess energy.

SMART HOME CONTROL, PERFECTED.
