Additionally at the time of purchase the 120A clamp listed on the same page was not compatible with the Shelly EM (different plugs). Had to return both items ### ⭐⭐⭐⭐ Reliable Wi-Fi energy monitor *by A***N on 19 January 2025* The Shelly EM is a reliable and effective Wi-Fi-connected energy monitor that integrates effortlessly with Home Assistant. Once set up, it works flawlessly and provides accurate energy monitoring with great convenience. However, there are a couple of drawbacks. Pairing took four or five attempts because it requires a 2.4GHz network, and my phone was initially connected to the 5GHz network (both share the same SSID). Additionally, it would benefit from a case or cover for the exposed live screw terminals. I had to resort to using electrical tape. Despite these issues, the Shelly EM is a solid choice for energy monitoring, particularly for those who use home automation tools such as Home Assistant. ## Frequently Bought Together - Shelly EM | Wi-Fi-operated Smart Energy Meter and Contactor Control Relay Switch | Home Automation | Works with Alexa & Google Home | iOS Android App | No Hub Required | Power Monitoring - Shelly Split Core Current Transformer 50A | Current clamp | Home automation | Compatible with Shelly EM | Single-phase installation | Current measurement --- ## 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.gr/products/486563949-em-wi-fi-operated-smart-energy-meter-and-contactor-control](https://www.desertcart.gr/products/486563949-em-wi-fi-operated-smart-energy-meter-and-contactor-control) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-24*
