ESP32 Energy Usage Monitor – Need Suggestions Before Starting
Olivia.Carter 2025-12-25 21:31:54 65 Views1 Replies Hi everyone,
I’m planning to build a small IoT project using ESP32/8266 to measure home energy usage through sensors and log the data for analysis.
Goal:
• Read real-time power consumption using CT sensor or pulse LED on meter
• Store/visualize data through serial/cloud/local dashboard
• Receive alerts when usage rises above a set threshold
I want advice from the community on:
1. Which sensor setup gives better accuracy for household load?
2. Any recommended libraries for ESP energy monitoring?
3. Is it better to start with CT (SCT-013) or read meter pulse output?
This is a learning project, so any guidance, similar projects or optimization tips are appreciated.
Thanks!
Thanks for the suggestions so far.
For a home energy monitoring setup, starting with a CT sensor like SCT-013 seems more practical, especially for non-invasive installation and real-time load tracking. Pairing it with an ESP32 and proper calibration should give reasonably accurate results for household usage.
I’m also planning to compare the sensor readings with actual monthly consumption data to validate accuracy. For reference, I typically review my utility units online via h fescoebillcheck.pk, which helps me match logged ESP32 data with actual billing cycles and identify variations over time.
Once the basics are stable, alerts and a local dashboard would be the next step.
