energieleser

The energieleser integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] fetches real-time consumption data reported by energieleser devices, such as stromleser.one, gasleser, wasserleser, and wärmeleser, using local HTTP API.

energieleser is a brand by nineti GmbH, a German company offering smart readers for utility meters.

Supported devices

The integration supports the following energieleser devices:

  • stromleser.one (electricity meter reader)
  • gasleser (gas meter reader)
  • wasserleser (water meter reader)
  • wärmeleser (heat meter reader)

Prerequisites

Ensure your energieleser device is connected to the same local network as your Home Assistant instance and its IP address is accessible.

For detailed hardware setup instructions, refer to the energieleser documentation.

Configuration

To add the energieleser device to your Home Assistant instance, use this My button:

energieleser can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.

Manual configuration steps

If it wasn’t discovered automatically, don’t worry! You can set up a manual integration entry:

  • Browse to your Home Assistant instance.

  • Go to Settings > Devices & services.

  • In the bottom right corner, select the Add Integration button.

  • From the list, select energieleser.

  • Follow the instructions on screen to complete the setup.

Configuration parameters

IP address

The IP address of your energieleser device. For example, 192.168.178.100.

Supported functionality

The energieleser integration primarily provides the following features based on the connected device type.

stromleser.one

  • Imported energy: Cumulative energy consumed (kWh)
  • Exported energy: Cumulative energy exported to the grid (kWh)
  • Active power: Current active power (W)
  • Phase power: Current active power for Phase 1, Phase 2, and Phase 3 (W)

gasleser

  • Total gas: Total gas volume measured by the meter (m³)
  • Gas flow rate: Current gas flow rate (m³/h)

Diagnostic sensors

  • Pulse count: Total number of pulses detected by the meter.

wasserleser

  • Total water: Total water volume measured by the meter (m³)
  • Water flow rate: Current water flow rate in liters per hour (L/h)
  • Volume flow rate: Current water flow rate in cubic meters per hour (m³/h)

Diagnostic sensors

  • Water today: Cumulative water consumed today (m³)

wärmeleser

  • Energy tariffs: Cumulative heat energy for tariff 1, tariff 2, and tariff 3 (MWh)
  • Power: Current thermal power (kW)
  • Total volume: Total volume of heating medium measured by the meter (m³)
  • Volume flow: Current flow rate of heating medium (L/h)
  • Temperatures: Flow temperature and return temperature (°C)
  • Temperature difference: Difference between flow and return temperature (K)

Common diagnostic sensors

  • Signal strength: Wi-Fi signal strength of the device (dBm). Disabled by default.

Data updates

The integration pollsData polling is the process of querying a device or service at regular intervals to check for updates or retrieve data. By defining a custom polling interval, you can control how frequently your system checks for new data, which can help optimize performance and reduce unnecessary network traffic. [Learn more] data from the device every 10 seconds over your local network.

Use cases

You can use the energieleser integration for a variety of smart home scenarios, such as:

  • Monitoring your energy consumption: Add the sensors to the Home Assistant Energy dashboard to track your daily, monthly, and yearly consumption of electricity, gas, water, or heat.
  • Automation based on usage: Trigger automations when electricity consumption goes above or below certain thresholds (for example, turn on appliances when excess solar power is being exported).
  • Detection of leaks and anomalies: Create alerts for continuous water flow or unusual gas usage patterns to detect potential leaks.

Automation examples

Below is an example automation to notify you when high power consumption is detected.

Automation: Alert on high power consumption 

automation:
  - alias: "High power consumption alert"
    triggers:
      - trigger: numeric_state
        entity_id: sensor.stromleser_one_active_power
        above: 5000
        for:
          minutes: 5
    actions:
      - action: notify.notify
        data:
          title: "High Power Usage"
          message: "Your active power consumption has been above 5kW for 5 minutes."

Known limitations

Rate limits: The energieleser devices can be overwhelmed by excessive HTTP requests. If you configure multiple apps or integrations to poll the same device simultaneously, the device may reach a rate limit or become temporarily unresponsive.

Troubleshooting

Cannot connect during setup

If you see a “Failed to connect” error during setup, verify that:

  • The energieleser device is powered on and connected to your network.
  • The IP address you entered is correct.
  • Home Assistant can reach the device on the local network.

Most energieleser devices are discovered automatically via zeroconf, so manual setup is rarely needed. If the device is not discovered, check that zeroconf/mDNS traffic is not blocked on your network.

Removing the integration

This integration follows standard integration removal. No extra steps are required.

To remove an integration instance from Home Assistant

  1. Go to Settings > Devices & services and select the integration card.
  2. From the list of devices, select the integration instance you want to remove.
  3. Next to the entry, select the three dots menu. Then, select Delete.
