Before moving on to advanced Zeus features, take a few minutes to verify that your core energy system is configured correctly.

This is an important step. Zeus can only make good calculations and decisions when the measurements it receives accurately represent your home.

At this stage you should have configured the energy sources and devices that are currently relevant to your installation.

You do not need to configure everything at once. Additional devices and features can always be added later.

Step 1 — Open the Command Center

Open:

AION EMS Zeus → Command Center

The Command Center gives you the quickest overview of whether Zeus understands your energy system correctly.

Depending on your installation, you may see:

Solar
Grid
House
Battery
Loads
Heat Pump
DHW · Heat Pump
Water Heater
Weather / Energy Prognose
Home Energy Timeline

Only components that are configured and available should appear.

Step 2 — Verify Solar Production

Compare the Solar value in Zeus with the current production reported by your inverter or Home Assistant.

For example:

Home Assistant: 4.8 kW
Zeus: approximately 4.8 kW

The values do not need to change at exactly the same moment. Different integrations have different update intervals.

However, large or persistent differences should be investigated.

Multiple inverters

If you have more than one inverter, make sure Zeus is not counting the same production twice.

Your total Zeus Solar value should represent the real total PV production of the installation.

Step 3 — Verify Grid Direction

The Grid flow is particularly important.

When your home is importing electricity, energy should flow:

Grid → House

When your home is exporting surplus energy:

House → Grid

Compare the Zeus value with your smart meter or Home Assistant grid entity.

If the number is approximately correct but the direction is reversed, review the Grid sign/direction configuration.

Do not compensate for a reversed Grid measurement by selecting an unrelated entity.

Step 4 — Verify House Consumption

House consumption represents the total electrical demand of the home.

A useful check is to switch on a known large appliance.

For example, turn on a device consuming approximately 2 kW.

The House value should increase by roughly the same amount.

It does not need to match to the watt because measurements may update at slightly different times.

Step 5 — Verify the Battery

If your installation has battery storage, compare:

State of Charge (SOC)
Charging / Discharging Power
Energy-flow direction

When charging, Zeus should show energy flowing toward the Battery.

When discharging, energy should flow:

Battery → House

The SOC displayed by Zeus should approximately match your battery integration.

You can also open:

Zeus → Battery Statistics

to verify charge/discharge history and battery activity.

Step 6 — Verify Your Heat Pump

If a Heat Pump is configured, compare Zeus with its original Home Assistant entities.

Check at least:

Electrical Consumption
Thermal Production
Operating State

For example:

HA electrical input: 700 W
Zeus Consumption: approximately 700 W

HA thermal output: 2.30 kW
Zeus Production: approximately 2.30 kW

When the compressor stops, Zeus should correctly represent the inactive or standby state according to the available evidence.

Step 7 — Verify Heating and DHW

If your Heat Pump provides separate Space Heating and DHW measurements, open:

Zeus → Statistics → Heat Pump

Check that:

Space Heating Consumption represents electrical energy used for heating.

Space Heating Generation represents thermal energy produced for heating.

DHW Consumption represents electrical energy used by the Heat Pump for domestic hot water.

DHW Generation represents thermal energy produced for domestic hot water.

These measurements must not be confused with each other.

If separate DHW information is configured, the Command Center can also show:

DHW · HEAT PUMP

as a clearly separated part of the Heat Pump information.

Step 8 — Verify Your Water Heater

If you have registered an independent Water Heater such as an ELWA, verify it separately from Heat Pump DHW.

Compare:

Current Power
Energy
Water Temperature

with the corresponding Home Assistant entities.

For example:

Home Assistant ELWA: 1,000 W
Zeus Water Heater: approximately 1,000 W

Remember:

Heat Pump DHW ≠ Independent Water Heater

Even if both devices heat the same tank, Zeus should treat them as separate energy consumers.

Step 9 — Verify Registered Household Devices

Open:

Zeus → Device Manager

Check that your registered devices show sensible live values.

When a device switches on, its measured consumption should appear in Zeus.

The Loads section of the Command Center separates registered device consumption from:

Unknown Consumption

Unknown Consumption is not necessarily an error.

It represents household demand that Zeus cannot currently associate with a registered device.

As you register more measured loads, the unknown portion can become smaller.

Step 10 — Check Energy Balance

Now look at the complete Command Center.

The energy flows should make physical sense.

For example:

Solar: 6.0 kW
House: 3.0 kW
Battery charging: 2.0 kW
Grid export: 1.0 kW

This is a balanced system:

6.0 kW produced = 3.0 kW consumed + 2.0 kW stored + 1.0 kW exported

Small temporary differences are normal because different sensors may update at different times.

Persistent large differences indicate that one or more mappings should be reviewed.

Step 11 — Check the Home Energy Timeline

The Home Energy Timeline translates important changes into understandable events.

Depending on your registered devices, you may see events such as:

Water Heater started
Water Heater stopped
Heat Pump activity
Registered load started/stopped

The timeline should represent real events.

Repeated start/stop events while a device is actually stable may indicate that its Power measurement fluctuates around an activity threshold.

Step 12 — Check Statistics

Open the available Zeus Statistics pages and compare the main values with Home Assistant.

Pay particular attention to:

Energy Statistics
Battery Statistics
Heat Pump Statistics

Daily values should represent the current period, while accumulated lifetime sensors should only be used where Zeus explicitly expects them.

Do not expect a lifetime total_increasing counter to equal today’s energy consumption.

Step 13 — Check Finance

If your electricity prices and tariffs are configured, open:

Zeus → Finance

Check that the configured:

Import price
Export compensation

match your actual electricity tariff.

Finance calculations depend directly on accurate Energy measurements and correct tariffs.

Verify the underlying energy system before relying on calculated savings.

Step 14 — Check System Status

Open:

Zeus → System Status

Look for warnings about missing or invalid measurements.

An Unavailable intelligence feature does not automatically mean something is broken.

For example, Zeus cannot calculate a reliable live COP if it does not have valid electrical and thermal power evidence.

Zeus should prefer:

Unavailable

over presenting a value that cannot be supported by the available measurements.

What Is Normal?

During verification you may notice small differences between Zeus and Home Assistant.

This is normal when:

  • sensors update at different intervals
  • an inverter updates faster than the smart meter
  • a battery changes direction between samples
  • a Heat Pump changes compressor output rapidly
  • measurements use different rounding precision

A difference lasting only a few seconds is usually not a problem.

Look for persistent discrepancies, not individual samples.

What Should I Fix?

Review your mappings if you see:

Solar production consistently too high
Possible duplicate inverter counting.

Grid direction reversed
Check sign/direction configuration.

House consumption clearly incorrect
Review the main energy-flow measurements.

Heat Pump Production always zero while HA shows thermal output
Check the Thermal Power mapping.

DHW Consumption appearing as Generation
Review electrical vs thermal mappings.

Battery charging shown as discharging
Review battery power direction.

Large unexplained Unknown Consumption
Check whether important household loads can be registered.

Do Not Map Sensors Just to Fill Empty Fields

This is one of the most important Zeus setup rules.

You do not need every field populated.

If your hardware does not provide a measurement, leave that field empty.

Zeus is designed to work with partial evidence and clearly indicate when a feature cannot be calculated.

Correct incomplete data is always better than incorrect complete data.

Your Zeus System Is Ready

When the Command Center matches the physical behavior of your home and the important measurements agree with Home Assistant, your core Zeus configuration is complete.

From here you can explore:

Energy Intelligence
Finance
Battery Statistics
Heat Pump Intelligence
Device Analytics
Home Energy Timeline

And, when you are ready:

Smart Control

We will leave EV Charging setup out of the public guide for now until we’ve properly tested and validated its setup path on real hardware. That’s consistent with how we’ve handled Heat Pump and ELWA support: validate first, document afterward.

Next: Smart Control

Verify the measurements first. Intelligence and automation come after the data is right.
