Use Cases

Avoid unnecessary energy usage by controlling the office equipment power supply

Avoid unnecessary energy usage by controlling the office equipment power supply

Stop unnecessary energy usage in the office over the weekend! Computers and monitors that somebody forgot to turn off, plugged chargers, lit up desk lights, printers and copy machines left switched on, etc. - all these appliances are consuming energy when nobody is in the office, unnecessarily burdening the monthly bills. Avoid that by setting Shelly Pro 1PM to cut off the power supply of the office appliances over the weekend to save on energy. Use smart scheduling functions to restore the power supply before the employees arrive at the office.
Efficient floor heating control

Efficient floor heating control

Make sure the temperature of your business facility or home is always welcoming – whether it’s a yoga studio, gym changing room, spa center, or your own living room! Control your floor heating based on the current weather forecast or create a scene with Shelly Pro 1PM and Shelly Flood and have the floor heating turned on whenever a decrease in floor temperature is detected.
Appliances control & monitoring

Appliances control & monitoring

Predict monthly costs and plan your spending better! Automate the electrical appliances in the restaurant and track their energy consumption wherever you are. Shelly will inform you in case an appliance is forgotten and left working outside of restaurant working hours, notifying you to switch it off to avoid electricity consumption waste. Additionally, you can set smart schedules and have Shelly cut off the power to all unused electrical appliances during the night and turn them back on right before the kitchen opens.
Preventative management

Preventative management

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 Pro 1PM, however, will immediately report the increase in energy consumption and will save you additional expenses on repairs or replacement of equipment.
