As a homeowner passionate about sustainability, I’ve always wanted to monitor my energy usage more effectively. After some research, I stumbled upon the Frient Energy Interface Meter, a battery-powered Zigbee device designed to track energy consumption. While it’s not cheap, the convenience and accuracy it offers have made it a worthwhile investment for me.
Here’s how I integrated it into my smart home setup:
-
Electricity Monitoring: I started with the Frient Electricity Meter Interface. It uses a magnetic optical sensor that simply clips onto my existing electricity meter. With Z2M (Zigbee2MQTT) integration, I now have real-time data on my energy consumption right in Home Assistant. It’s fascinating to see how much energy each appliance uses!
-
Gas Meter Integration: Inspired by the success with the electricity meter, I wanted to extend this to my gas meter. Since the Frient doesn’t support gas meters directly, I decided to DIY a solution using a hall effect sensor module. This involved some wiring and configuration, but the result was seamless integration with my Zigbee network.
-
Automation & Dashboard: To make the data actionable, I created a custom dashboard in Home Assistant. It displays both electricity and gas usage in kWh, with daily and weekly trends. I also set up automations to alert me if energy usage spikes, helping me identify inefficient habits or malfunctioning appliances.

Tips & Tricks:
- Battery Life: The hall effect sensor I used had an LED for debugging, which drained the battery faster. I removed the LED once everything was set up to improve battery life.
- Configuration: Adjusting the pulses per kWh setting in Z2M was crucial for accurate readings. I also created a template sensor to convert gas usage from cubic meters to kWh for consistency.
- Placement: Positioning the sensor correctly on the meter was key. I used some Blu-Tack to keep it steady and ensure reliable readings.
This setup has not only helped me monitor my energy usage but also made me more conscious of my consumption patterns. It’s a small step toward a more sustainable lifestyle, and I’m excited to see how it evolves over time!
If you’re looking to get started with energy monitoring, I highly recommend exploring similar solutions. It’s a rewarding project that pays off in the long run. Happy tinkering!
