Shelly is one of the fastest growing IoT brands in the world. We offer intelligent solutions for automation of homes and buildings with our smart home devices. Inspired by you and with the aim of allowing a soul-quiet and happy life in your own home, we develop our devices with attention to the smallest detail. Intelligent 3-phase energy meter with contactor control Many appliances, apartments and buildings consume more energy than they need, resulting in energy waste and higher expenses. Shelly 3EM is a smart, professional 3-phase energy meter that helps monitor power consumption in real time and be notified when a device or system consumes more power than the preset limit. In addition, it allows for protection control. Three independent measuring channels each with up to 120 A Contactor control (or load up to 10A) Power, voltage, current, total energy and power factor reports 365 days of internal storage in case Wi-Fi is not available Includes 3 x 120 A current converters Easy control via the Shelly app, various protocols and platforms as well as voice assistants Wi-Fi Connect Shelly 3EM to your Wi-Fi network. No hub required! Power monitoring Shelly 3 - monitors single-phase electrical systems with up to 3 points at the same time. 365 days data storage Shelly 3EM measurements are stored in a free cloud for 365 days. Contactor control Shelly 3EM has an integrated 10A relay output for contactor control. 2-way energy consumption monitoring Monitor your home, office or factory and avoid additional costs or voltage drops that can damage your devices and equipment. Shelly 3EM can calculate 2-way consumption: generated and consumed energy for each of the three phases. The device can be configured to measure three separate circuits of a single-phase mains and control a contactor. Display the quality of your mains in terms of active power, blind power, voltage and power factor. Smart and efficient car charger Designed to monitor one, two or three phases, Shelly 3EM allows you to monitor the status and history as well as current and past power consumption of each individual channel for the day, week, month or year. Shelly 3EM exports all data in CSV format at 10 minute intervals, making data analysis and cost reduction easier. This allows you to monitor the exact energy consumption of your electric car and calculate what proportion it has in your electricity bill. Monitoring and control of solar panels Keep track of how much energy your solar panels and wind turbines generate and save effortlessly. Shelly 3EM provides real-time information on the efficiency of solar and wind energy systems as well as historical data on the amount of energy generated and consumed. So you can control the energy flow and get the most out of your solar and wind turbines. If you want to go one step further, connect a contactor to Shelly 3EM so you can automatically turn off unnecessary devices in your home to save energy. Preventive monitoring If an electrical device is damaged, it does not simply stop its operation. Usually it increases energy consumption to compensate for its operating capacity. Since there is no visible difference in performance, it can take months for you to spot a problem resulting in inefficiency and energy waste. The Shelly 3EM energy monitoring immediately shows the increase in energy consumption and notifies you, so you can save additional costs on repairs or replacing devices. Specifications Full compatibility Shelly devices are compatible with Alexa, Google Home, Android and iOS. Together with the voice assistant, you can control Shelly devices only with your voice Review: Shelly 3EM + EcoFlow PowerStream - Whilst this is a 3 phase meter, it is equally happy on a single phase system - just link all 3 inputs together. It's very easy to install, but does require a 240Vac supply - easily found if it's being installed into a consumer unit. Wi-fi connection is simple enough but will require a smartphone/tablet/laptop etc to get it set up. The Shelly app works well and keeps a log of energy usage for its own graphs. The meter also understands the concept of feeding energy back into the grid (PV etc). This model can also be integrated into the EcoFlow system to control the output of their PowerStream micro-inverters to maximise the usage of "home grown" energy before taking expensive units from the grid. It works well in that respect. Review: Works well, easy to install and use - Responsive device, with a decent app and the added bonus that it will integrate with the Ecoflow app (the actual reason I bought it). I bought a separate enclosure for it and wired it into that. Seems to have no problem maintaining a WiFi connection and helps me avoid giving any solar back into the grid. ## Features - Shelly 3EM is a Wi-Fi-Smart 3-phase professional energy meter with contactor control with three independent measurement channels up to 120 A each,Contactor control (or load up to 10 (A).Many appliances, homes, and buildings use more energy than they need, leading to energy waste and higher spending.

I bought a separate enclosure for it and wired it into that. Seems to have no problem maintaining a WiFi connection and helps me avoid giving any solar back into the grid. ### ⭐⭐⭐⭐⭐ Shelly just works...... *by U***L on 16 May 2026* As always shelly does it again. Works well once paired via shelly app. Works in tandem with ecoflow stream. The good thing is you can use normal two wire power cable with plug on the end and works fine. No need to add to fuse box. ## Frequently Bought Together - Shelly 3EM | WiFi 3 Channel Smart Energy Meter with Contractor Control Relay Switch | Home Automation | Compatible with Alexa & Google Home | iOS Android App | No Hub Required | Power Monitoring - Shelly 1 Mini Gen3 | WiFi Smart Switch Relay 1 Channel 8A | Home Automation | Bluetooth Gateway | Compatible with Alexa & Google Home | iOS Android App | No Hub Required | Dry Contacts - Shelly Shelly H&T Gen 3 - Wi-Fi & Bluetooth Temperature, Humidity Sensor & Weather Station (White, Wall Mountable, No Hub Required) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/504153444-3em-3-channel-wifi-smart-energy-meter-with-contactor-control](https://www.desertcart.tn/products/504153444-3em-3-channel-wifi-smart-energy-meter-with-contactor-control) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-30*
