Yo no tengo mas productos de Shelly, así que no puedo opinar sobre la integración domótica. Lo uso para el monitoreo de las placas solares. La app te permite monitorizar en tiempo real el consumo de energía de la vivienda, la producción de las placas solares y el volcado/consumo de red o baterías. Gráficas diarias, por mes, año, etc. Funciona con la wifi de casa y te da información suficiente y bastante exacta sobre tu consumo energético en cualquier momento y lugar. Solo encuentro a faltar en la app, disponible en apps de otos medidores (y otros precios), el diferenciar el consumo por electrodoméstico. De momento sin problemas de funcionamiento y satisfecho con la comprs. ### ⭐⭐⭐⭐⭐ Excellent quality product. *by on Reviewed in Ireland 10 June 2025* Item worked as described. ### ⭐⭐⭐⭐ Works great! Just be sure the clamps face the right direction *by on Reviewed in Australia 4 July 2024* I had to have the electrician come back as the clamps that go onto the main are hard coded to incoming or outgoing power. I don't know why they built it that way as the signal clearly comes through just fine either way...just negative when it should be positive.It's great to know how much power I'm using and it was very quick to setup with home assistant for automations based on power usage. I've paired it with some outlet meters from Shelly which are working great to know if I'm actively sitting in the office based on power usage for some useful automations. ## Frequently Bought Together - Shelly Pro EM 50A | Wi-Fi & LAN Energy Meter with Contactor Control | DIN-Rail | Home Automation | Bluetooth Gateway | Compatible with Alexa & Google Home | No Hub Required | Power Monitoring - Shelly Pro 4PM | Wi-Fi & LAN, 4-Channel Smart Relay with Power Metering | Home Automation | Compatible with Alexa & Google Home | iOS Android App| Remote Appliances Control and Monitoring - Shelly Pro 3EM (120A) | Wi-Fi & LAN, 3-Phase Smart Energy Meter | 2-Way Consumption | Home Automation | Bluetooth Gateway | Compatible with Alexa & Google Home | No Hub Required | Solar Panels --- ## 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/740943372-shelly-pro-em-50a-wi-fi-and-lan-energy-meter](https://www.desertcart.tn/products/740943372-shelly-pro-em-50a-wi-fi-and-lan-energy-meter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-12*
