Sensors

The ista EcoTrend integration exposes the last monthly readings as sensors. It provides the following sensors:

• Heating: readings from your heat cost allocators (measured in units)
• Heating energy: estimated value in kWh
• Heating costs: estimated costs in EUR
• Hot water: consumption readings in m³
• Hot water energy: estimated value in kWh
• Hot water costs: estimated costs in EUR
• Water: consumption readings in m³
• Water costs: estimated costs in EUR

Not all values may be available in your ista EcoTrend account. Cost estimation is an optional service that has to be booked by your property manager or lessor. Therefore, the cost sensors are deactivated by default.

Long-term statistics

The ista EcoTrend integration allows you to import all your historical consumption readings from your ista EcoTrend account into long-term statistic entities. These entities can be displayed in your Home Assistant energy dashboard, providing a comprehensive view of your consumption data over time.

Identifying ista EcoTrend statistic entities

The statistic entities imported via this integration have a ista_ecotrend: prefix. This prefix helps you identify and distinguish these entities from other sensor statistics when setting up the long-term statistics in the energy dashboard.

Setting up long-term statistics in the energy dashboard

To set up the ista EcoTrend long-term statistics in your Home Assistant energy dashboard, follow these steps:

• Access the energy configuration panel

  • Go to the energy configuration panel of your Home Assistant instance.

    

• Add heating energy usage

  • Go to Gas consumption.
  • Select Add gas source.
  • Choose your Heating energy entity (for example, ista_ecotrend:luxemburger_str_1_heating_energy).
  • For cost tracking, select the Use an entity tracking the total costs option.
  • Select the corresponding Heating costs entity (for example, ista_ecotrend:luxemburger_str_1_heating_cost).

• Add hot water energy usage

  • To track hot water energy usage and costs (for example, ista_ecotrend:luxemburger_str_1_hot_water_energy and ista_ecotrend:luxemburger_str_1_hot_water_cost), repeat the above steps for your Hot water energy and Hot water costs entities.

• Add hot water consumption

  • Go to Water consumption.
  • Select Add water source.
  • Choose the Hot water entity (for example, ista_ecotrend:luxemburger_str_1_hot_water).
  • For cost tracking, select the Use an entity tracking the total costs option.
  • Select the corresponding Hot water costs entity (for example, ista_ecotrend:luxemburger_str_1_hot_water_cost).

• Add water consumption

  • To track cold water consumption and costs (for example, ista_ecotrend:luxemburger_str_1_water and ista_ecotrend:luxemburger_str_1_water_cost), repeat the above steps for your Water and Water costs entities.

Data updates

The integration checks for new readings every 24 hours.

Known limitations

• The integration does not support two-factor authentication. To connect Home Assistant to ista Ecotrend, you must first disable two-factor authentication. To do this, navigate to Menü -> Benutzerkonto -> Zwei-Stufen-Authentifizierung and remove any registered authentication devices.
• Sensor values reflect the meter readings from the previous month, as ista publishes new readings a few days after the end of the billing period. Long-term statistics are adjusted to display these readings as of the last day of the corresponding month.
