Choose a time and create custom daily schedules for your Shelly 3EM.
Anti energy theft protection
Monitor real-time energy consumption for each phase and compare it to the neutral to know if someone is stealing electricity.
Shelly 3ЕМ can also monitor monophase electrical systems with up to 3 points simultaneously.
Why Shelly 3EM
The professional 3-phase energy meter.
Shelly 3EM can calculate 2-way consumption: produced and used energy for each of the three phases. The device can be configured to measure three separate points of a mono-phase electrical system and measure each of them separately.
Connect in a minute & control it all
Shelly 3EM has integrated relay output which can be used for contactor control. Real-time and historical information about the efficiency of the solar or wind energy system and how much energy has been produced. Control your monthly expenses by saving on money and energy!
365 day built-in energy history
We developed Shelly 3EM to allow you to monitor the status and history, as well as the current and past electrical power consumption for the day, week, month, or year. Shelly 3EM exports all data in CSV format in 5-minute intervals. The information can help for analysis and detailed statistics. All data gets stored in the cloud at incrementing intervals.
The perfect solution for
Shelly 3EM can do all the work for you. The 3-phase energy meter can calculate energy cost for production, notify you if a machine is powered on during non-working hours, measure the real working time of each machine and allows remote On/Off control for power optimization.
Shelly 3EM will automatically shutdown and notify you when the defined consumption limit is exceeded.
Оptimize energy usage
Ever wanted to live sustainаbly and save energy, money, and CO2? With Shelly 3EM, you can monitor the consumption оf each circuit, appliance, or of your whole home to optimize energy usage. In case you have solar panels or wind turbines, you can be aware how much energy was produced and make savings effortless.
Detailed info about electricity consumption
Often, when you are at home and doing various things at the same time, you can miss out on the postman or your guests. Avoid these situations with Shelly 1 as it allows you to connect it to your doorbell and receive an instant notification when someone is at the front door.
One application countless possibilities
