IoT smart energy meter with appliance-level insights
Measure household or lab energy use in real time, show it on a web dashboard, and estimate which appliances are running from the load profile.
Scope
- Measure voltage, current, power factor and energy with calibrated sensors.
- Stream readings over Wi-Fi (MQTT) to a dashboard with daily and monthly totals and estimated bill.
- Attempt simple load disaggregation (identify AC, fridge, iron) from power signatures.
Safety
Work with mains voltage only under supervision and use isolated, rated sensors.
