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. ### ⭐⭐⭐⭐⭐ Accurate energy monitoring. *by on Reviewed in the United Kingdom 9 August 2026* This smart meter works with the Ecoflow stream solar battery system, allowing accurate monitoring of energy usage through Ecoflow and Shelly apps and allows Ecoflow to regulate power preventing grid feed-in. The device makes it easy to identify wasted energy and save money. ### ⭐⭐⭐⭐⭐ Shelly 3em *by on Reviewed in the United Kingdom 29 June 2026* Works as I need it to in the ecoflow app but unfortunately the micro inverter is not working as I originally purchased it for but the shelly 3em is functioning correctly.No need to purchase the expensive one !! ## 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.com.br/products/504153444-3em-3-channel-wifi-smart-energy-meter-with-contactor-control](https://www.desertcart.com.br/products/504153444-3em-3-channel-wifi-smart-energy-meter-with-contactor-control) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-25*
