Easy control through the Shelly app, various protocols, and platforms, as well as voice assistants
Many appliances, homes, and buildings use more energy than they need, leading to energy waste and higher spending. Shelly 3EM is a smart 3-phase professional energy meter that will help monitor electricity usage in real-time and get notified in case an appliance or system consumes power above a pre-set threshold. Additionally, it allows for contactor control Smart energy metering will help you identify and eliminate any redundant energy consumption.
Wi-Fi Operated
Connect Shelly EM to your Wi-Fi network. No HUB required!
Power Monitoring
Shelly ЕМ monitors monophase electrical systems with up to 3 points simultaneously.
Contactor control
Shelly EM has an integrated 10A relay output for contactor control.
365 days of data storage
The measurements from Shelly EM are stored in a free cloud for 365 days.
Custom schedules
Set custom schedules based on a daily agenda or working hours.
2-way energy consumption monitoring
Shelly 3EM can calculate 2-way consumption: produced and used energy for each of the three phases.
Smart and efficient car charger
you can monitor the exact energy your electric car consumes and calculate what part of your electricity bill it forms.

Thanks for your video, may i know the update interval of the current and voltage in home assistant, is it possible to use it as a real time power monitors?
Yes, within 1 second I got the data if I start a relevant electrical consumer.
Hello. I have 2 air conditioners and I want to track their energy consumption. There are 2 options. shelly pro em50 and pro 3em. Air conditioners are on the same floor and receive energy via a single phase. In this case, will a and b phase and, if necessary, c phase transformer make separate measurements on the same phase cable?
Hello! Yes, check the user guide of the devices. 1 Phase wiring up to 3 different circuit. kb.shelly.cloud/__attachments/63832224/User%20and%20Safety%20Guide%20-%20Multi%20language?inst-v=b55123a4-d0b9-4d6b-867c-5b22f51d64a3
@@ezesaz5021 thank you.
Hi, can I get consumption per user when I add different users? I am looking for a solution to split the electricity usage bill in a common area to its users. Can Shelly em do that? If you help me I will be so happy.
Hi! What do you like to measure? Different flats, equipmet, ... With Shelly 3M you can measure a 3 phase supply or 3 different circuit for e.g. 3 different flats. You can use more 3M or use other relays with measurement (Shelly Plus 1PM, , what the users can check as well.
@@ezesaz5021 First of all, thank you very much for your feedback. I guess I didn't express my need clearly. Our multi-storey building has a auto parking, and there are common charging sockets and car charging stations in the autopark. Normally, the bill that came as a result of electricity consumption such as lighting in the parking lot was paid jointly by the building. But now electric cars have become commonplace and they need charging. But not every occupant of the building has an electric vehicle, some have more than one electric vehicle. So I'm looking for a way to divide the electricity by the usage amount to the users. Since there are too many flats, occopants it does not seem possible to separate the phases of the building for each flat, to use a measuring device for each and to use a separate electrical outlet for each, both in terms of cost and appearance. Instead, I am looking for a system where the electricity output is active by account and the electricity usage of the each user is measured. For example when an user login system, he can open electric switch then system can add electric usage of him. When he log from system electric will gone.
Hello! Milyen távolságra van az eszköz a routeredtől? Nincs gond a kapcsolódással?
Szia! 5 m-re van és egy fal választja el a routertől. 2 hónap alatt egyszer volt, hogy a router újra indításával helyre kellett hozni a kapcsolódást. Szerintem jól működik.
