The IOmeter {% term integration %} fetches data from your IOmeter device, by using the local HTTP API.

IOmeter is a German company that provides the IOmeter device for reading electricity meters.

{% important %} In order for the IOmeter to be used by Home Assistant, the Core/Bridge firmware version should be at least 62/69. {% endimportant %}

Configuration parameters

{% configuration_basic %} IP address: description: The IP address of your IOmeter. {% endconfiguration_basic %}

Data updates

The integration will update its sensors by polling the IOmeter Bridge every ten seconds for new values. We recommend using USB-C power for the IOmeter Core instead of batteries.

Available sensors

The following sensors are supported:

• Power (W): Active power
• Total energy usage (kWh): How much energy the meter used
• Total energy returned (kWh): How much energy the meter returned to the grid
• Meter number: Electricity meter number
• Pin status: Electricity meter pin status
• Core battery level: Battery level of the IOmeter Core in percent
• Core power status: Battery or USB-C power for the IOmeter Core
• Signal strength WiFi: WiFi connection strength of the Bridge
• Signal strength Core/Bridge: Sub-GHz connection strength between Core and Bridge
