The meter has a clear display that makes it easy to check power readings directly on the device. What I particularly like is how easily it can be integrated into DIY home automation projects. I connected it to an ESP8266 NodeMCU using an RS485 interface and integrated the readings into Home Assistant through ESPHome. One of the biggest advantages is that ESPHome already has a dedicated SELEC meter component with the required register handling and support for various measurement values. You mainly need to configure the component in your ESPHome setup and connect the hardware correctly, rather than manually implementing the register communication from scratch. This makes integration much easier for DIY enthusiasts. I can now monitor parameters such as voltage, current, active power, power factor, frequency, and import/export energy directly on my custom Home Assistant dashboard. It is very useful for understanding household electricity usage and building personalized energy monitoring automations. What I liked: 1. Clear and easy-to-read display. 2. Multiple useful electrical measurements in one device. 3. Dedicated ESPHome component with register handling and support for various sensor values. 4. Convenient integration with ESP8266/ESP32-based projects using a compatible RS485 interface. 5. Works well for creating a customized Home Assistant energy dashboard. 6. Great potential for DIY IoT, smart-home automation, and real-time energy monitoring. Overall, this is a useful choice for anyone interested in home energy monitoring, IoT projects, or smart-home automation. If you enjoy building your own monitoring system instead of depending entirely on a proprietary app, this meter is worth considering. Make sure to follow the electrical safety requirements and verify the wiring, RS485 communication settings, and ESPHome configuration before connecting it to your system.

Just install an energy meter in your main MCB line. Catalog and wiring diagram will be provided along with the product. **Q: Can I install this to monitor entire home wattage consumption ? and what is the accuracy ?** A: so far not installed properly , due to non availablity of the electrician.. **Q: does it require a Current transformer separately? Can we reset the Energy reading.** A: CT not required bro **Q: What is the max kW capacity?** A: as of now , i did not used it.. next week i am going to install it.. there is no limit i guess it can get as per the digit.. and productions of your power source.. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Energy Meter for DIY Smart Home and Home Assistant Integration *by A***H on 29 October 2026* I purchased the SELEC EM2M-1P-C-100A multifunction energy meter for my home energy monitoring project, and it has been a great addition to my smart home setup.

Perfect meter for household (single phase) metering application. 2. MODBUS protocol allows interfaces over IoT to other boards for remote monitoring of power consumption. 3. MODBUS communication is isolated from mains high voltage (safe to use). 4. Monitor all parameters -- V, I, PF, Freq, KVAR, KW, KVA.. 5. User manual explains all address and means to interface with MODBUS master. 6. Form factor is same as MCB. Hence fits perfectly inside switch box. 7. Made in India. Cons: - 1. Slightly expensive. 2. Manufacturer (Selec) never responded to any of my query. I had received replies from China and Taiwan for similar meter, but never from Selec (Mumbai). ## Frequently Bought Together - SELEC EM2M-1P-C-100A Multifunction energy meter 1 phase (SPECTRUM TECHNOLOGY) - EM4M-3P-C-100A Three phase DIN RAIL Energy Meter --- ## 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.in/products/222997731-selec-em2m-1p-c-100a-multifunction-energy-meter-1-phase](https://www.desertcart.in/products/222997731-selec-em2m-1p-c-100a-multifunction-energy-meter-1-phase) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-11-12*
