The problem behind the bill
A higher electricity bill tells you what you owe—not what caused it
A utility bill shows a total. It does not show when the electricity was used, which loads created the peak or whether an appliance ran longer than expected.
Monthly electricity bill
$186
Useful for payment. Not enough for diagnosis.
?What caused the overnight base load?
?When did the daily peak occur?
?How much did heating, cooling or a water heater cost?
?Did the change I made actually reduce consumption?
From data to action
Measure the whole home continuously, then act on evidence
IAMMETER combines a DIN-rail Wi-Fi energy meter with dashboards and reports designed to turn panel-level measurements into useful household decisions.
LIVE
See power now
Watch real-time demand and immediately see the effect of switching a large load on or off.
COST
Understand the bill
Set electricity tariffs and track estimated daily, monthly and billing-period cost.
ANALYZE
Find patterns
Compare hours, days and meters to identify base load, peaks and unusual consumption.
VERIFY
Confirm savings
Measure before and after a change instead of guessing whether it reduced electricity use.
Made for residential systems
Choose the IAMMETER model that matches your home supply
Start with the electrical system, then decide whether you need one measurement point or two. These are IAMMETER's primary residential models.
Two measurement channels
WEM2067
For a split-phase home, or a single-phase home that needs two independent measurement points.
- Monitor both split-phase lines
- Or monitor the whole home plus a dedicated circuit
- Can monitor grid plus a single-phase solar inverter
- IAMMETER-Cloud Basic included
Three measurement channels
WEM3050T
For residential properties supplied by three-phase electricity.
- Monitor all three phases
- Suitable for three-phase residential loads
- Compact residential monitoring choice
- Cloud, API, MQTT and Home Assistant
Commercial or industrial project? Other IAMMETER three-phase and CT-operated models are designed for larger installations. This page focuses on residential monitoring.
Simple path to useful data
From the electrical panel to a clear home-energy view
1 · SelectMatch the meter to single-phase, split-phase or three-phase residential supply.
2 · InstallHave the meter and CTs installed at the correct point in the electrical panel.
3 · ConnectConnect Wi-Fi and add the device to IAMMETER-Cloud or a local platform.
4 · AnalyzeSet tariffs, build a baseline and look for peaks, waste and measurable savings.
Use your data your way

The right tool for totals, trends and major loads
| Question | Whole-home IAMMETER monitoring |
|---|---|
| How much electricity is the home using now? | Measured in real time |
| How many kWh did the home use today or this billing period? | Recorded and reported |
| When did the peak or abnormal load occur? | Visible in trends and analysis |
| What is the estimated electricity cost? | Calculated from configured tariffs |
| Which exact appliance used every kWh? | Not automatically identified from one whole-home meter; use dedicated sub-metering for important circuits |
