Electrical Measurements

Devices that expose electrical measurement properties (power, voltage, current, energy, or produced_energy) will have these values exposed to HomeKit using custom Eve-compatible characteristics.

These characteristics are visible in apps that support custom HomeKit characteristics, such as the Eve app.

Supported Properties

The following table shows the supported exposes entries and the corresponding characteristics:

Expose Name	Alternative Names	Characteristic Name	Characteristic UUID	Unit
power	active_power, load	Consumption	E863F10D-079E-48FF-8F27-9C2605A29F52	W
voltage	mains_voltage, rms_voltage	Voltage	E863F10A-079E-48FF-8F27-9C2605A29F52	V
current	-	Current	E863F126-079E-48FF-8F27-9C2605A29F52	A
energy	consumed_energy, energy_consumed	Total Consumption	E863F10C-079E-48FF-8F27-9C2605A29F52	kWh
produced_energy	energy_produced	Total Production	E863F10C-079E-48FF-8F27-9C2605A29F52	kWh

Note: Total Consumption and Total Production share the same UUID (E863F10C) because the Eve app and other HomeKit apps recognize this UUID as a kWh energy measurement. The characteristic name provides the context (consumption vs. production), while the shared UUID ensures apps correctly interpret and display the value in kilowatt-hours.

Service UUID

All electrical characteristics are added to a custom service with UUID 00000001-0000-1777-8000-775D67EC4377.

Produced Energy

For devices that support bidirectional energy measurement (such as solar inverters), the produced_energy property is exposed as a separate service to distinguish it from consumed energy.

Multi-Endpoint Devices

For devices with multiple endpoints (e.g., multi-gang power monitoring switches), a separate electrical sensor service will be created for each endpoint.
